P.O BOX 2128
HARARE
TREE LIFE
We are now into the third month of our year, and if by some oversight you
have not paid your $25 subs for the 1994/95-year, please do.
MASHONALAND CALENDAR
Saturday 4th June (WINTER). Botanic Garden Walk at 10.45 for 11.00 a.m.
The Herbarium gates are locked during the weekends but there will be a
security guard at the public car park and this is where we will meet Tom.
Sunday 19th June. Out intended venue at Wedza is very dry and suffering
from early leaf drop so there is a switch to a riverine site on Mr. and
Mrs. P Butler's, Marsala farm off the Shamva Road. There are a good variety
of trees, some not that common. Directions: Leave Harare on the Enterprise
Road, turning the left fork to Shamva at the Y junction 21km from town.
Almost exactly opposite the 27.5 km peg, turn right onto Marsala Farm
(48.5 km from Harare). Follow this dirt road for 1 km and turn left at
the T-junction. After 200 meters turn left again and follow the track
and Tree Soc. signs, cross a little bridge and find a parking place. Watch
out for well-disguised speed humps on the dirt road. Total distance from
Harare is about 50 km and all but 1.5 is on tar.
Saturday 25th June. Botanic Interest Walk; we meet Mark at Newlands Shopping
Centre on the Enterprise Road in the car park near Squabbles Restaurant.
Head out of town on the Enterprise rd, pass the Gremlin drive-in Restaurant
on the right and shortly after, as the dual carriageway section starts
at Newlands, take the first turning right. Then immediately turn left
and park in the car park on the right. Time 3 p.m. as usual.
Saturday 2nd July. Botanic Garden Walk
Sunday 17th July. To a dam in the Marondera area
Saturday 23rd July. Botanic Interest Walk
MATABELELAND CALENDAR
Sunday 5th June. An all day visit in the Fort Rixon Area so bring the
usual life-sustaining essentials. We depart from Girls' College at 8.30
and our first stop will be at Fort Rixon Club to look at its facilities
and to get tea out of the way. The main interest is at ENGOMENI the Meikle’s
Game Ranch set in miombo woodland and about 5 km from the club. If time
permits in the afternoon, we will move on to Dlodlo Ruins, which are close
by. The round trip is less than 200 km and the roads are quite good, with
the first 47km on tar.
Sunday 3rd July. Aloe time in Nata; this will be a long all day trip.
Sunday 7th August. To Chesa Forest, which will most probably be an all
day trip as well.
BOTANIC GARDEN WALK: 3 MAY 1994
Sapindaceae continued
The second instalment of the Sapindaceae began with the genus Allophylus.
This has compound leaves with 3 leaflets (trifoliate) and (often) has
domatia present in the axils of the veins on the underside of the leaf.
These appear as small pockets of hairs.
Five species were examined:
1. Allophylus chaunostachys is a shiny-leaved species of rain forests
and occurs at low altitudes in Zimbabwe, for example at the Haroni/Rusitu
con¬fluence.
2. Allophylus alnifolius: Another species with shiny leaflets, this is
a low-altitude species, occurring often in riverine vegetation.
3. Allophylus chirindensis: A very rare species of the Chirinda Forest
with striking large leaflets, some over 15 cm long.
4. Allophylus africanus: This, of course, is the well-known species that
is so common around Harare and which can easily be thought to be a Rhus.
However, Rhus never have domatia and the fruit of a Rhus are usually flattened,
whereas Allophylus fruits are not. Allophylus africanus has relatively
hairy leaves, whereas the other four had more or less shiny leaves.
5. On to Allophylus abyssinicus, which we discussed last month, which
occurs in disturbed sites (e.g.) in the Honde Valley. This species had
the most striking domatia – enormous pockets easily visible to the
naked eye.
Leaving Allophylus, we saw Zanha africana, with its pinnate leaves that
lack a terminal leaflet (i.e. they are paripinnate). This is a well-known
species occurring quite commonly on granite kopjies and in woodland. It
is similar to the much rarer Zanha golungensis.
Pappea capensis, another common and readily recognisable species, often
on granite kopjies and termite mounds, has simple leaves that are serrate.
Often, on young leaves, the leaf edge is also spiny.
Pancovia golungensis has only been found in forests in the Burma Valley
(in Zimbabwe) and is one of the rarest members of the family. Although
Tom does have this in the Botanic Gardens, it is a very poor specimen.
We took another look at Stadmania oppositifolia, which has very shiny
pinnate leaves. It occurs in the S of Zimbabwe – anywhere where
there is an influence of guti – for example on Lone Star Ranch near
Chiredzi. The bark is very smooth and the buds densely hairy.
Finally, we saw Erythrophysa transvaalensis with its extraordinary inflated
fruits, which are a bit like Cardiospermum a climbing species (also Sapindaceae).
The leaves are pinnate and have a winged rhachis. This was only discovered
in Zimbabwe about 8 years ago, having presumably been overlooked before.
Finally, to round off the evening, and finding ourselves in the Matabeleland
section of the Gardens, we were shown some of the characteristic species
of the Matopos.
Many thanks to Tom for another fascinating walk. Next month, Tom intends
to look at the genus Rhus.

Visit to new Road to Mazwi Game Reserve north of Bulawayo
On the 4th of April a pleasingly large turnout of people paid a visit
to the new Road to Mazwi on a cool windy morning. In an area of cyanite/granite
and mopane-clay an interesting array of species was encountered.
The good thing about tree society visits is that one always seems to learn
something new on each trip. For example we were able to see that Combretum
zeyheri and Combretum collinum sometimes have leaves inn whorls like the
better-known Combretum adenogonium.
A new one for me was Psidia punctulata identified by Charles Sykes via
Brian Best long ago. This is an interesting shrub in the Asteraceae, with
yellow flowers and shiny resinous looking leaves.
The first stop yielded the following trees:
Acacia galpinii, Acacia gerrardii, Acacia nigrescens, Acacia nilotica,
Albizia amara, Albizia tanganyicensis, Aloe excelsa, Azanza garckeana,
Bridelia mollis, Canthium lactescens, Cassia abbreviata. Clerodendrum
glabrum, Colophospermum mopane, Combretum apiculatum, Combretum collinum,
Combretum molle, Combretum zeyheri. Commiphora mollis, Dichrostachys cinerea
(several forms), Diplorhynchus condylocarpon, Euclea divinorum, Euclea
natalensis, Euphorbia ingens. Ficus abutilifolia, Ficus glumosa, Ficus
ingens, Ficus thonningii, Flacourtia indica, Flueggea virosa, Gardenia
resiniflua, Gardenia ternifolia, Gardenia volkensii. Grewia bicolor, Grewia
flavescens, Grewia monticola, Grewia retinervis, Kirkia acuminata, Lannea
discolor, Maytenus senegalensis, Ozoroa insignis. Pappea capensis, Pavetta
eylesii, Pavetta gardeniifolia, Pavetta schumanniana, Peltophorum africanum,
Piliostigma thonningii, Pouzolzia mixta, Pseudolachnostylis maprouneifolia,
Psydrax livida. Pterocarpus angolensis, Pterocarpus rotundifolius, Rhus
leptodictya, Sclerocarya birrea, Strychnos madagascariensis, Terminalia
sericea, Vangueria infausta, Vitex payos, Ximenia caffra, Ziziphus mucronata.
We then drove a little further down the road for lunch and tea after which
some people went to other engagements. Seeing the additional spp. below
rewarded those who stayed on.
Acacia ataxacantha, Acacia karroo, Combretum hereroense, Commiphora mossambicensis,
Commiphora pyracanthoides, Croton gratissimus, Dalbergia melanoxylon,
Elaeodendron matabelicum, Elephantorrhiza goetzei, Ochna holstii Ochna
puberula, Tarchonanthus camphoratus, Terminalia randii, Terminalia brachystemma,
Terminalia trichopoda, Ximenia americana.
An interesting day and worth another visit.
Charles Sykes and Tom Raub did go back for another visit and were able
to bring the tally up to 100 odd spp.
The following shrubs were also seen:
Cissus cornifolia, Dregea macrantha (a climber), Jasminum sp., Maytenus
heterophylla, Psidia punctulata, Rhigozum obovatum.
Succulents seen included
Aloe aculeata, Aloe chabaudii, Aloe greatheadii Euphorbia espinosa Euphorbia
griseola Euphorbia schinzii
Anthon Ellert
RENCO MINE Saturday 16th April
We had been warned that the access road to Renco Mine, situated in a largely
forgotten corner of Zim¬babwe, was rough so it was a relief to stop
and consult the notice board at the mine gate. Investigating one of the
many very green shrubs near¬by, Maureen returned triumphant with a
cluster of the unusual paired fruits belonging to the Toad Tree –
Tabernaemontana elegans.
The football grounds seemed an unlikely place to pitch tents but it served
us well and towards evening the familiar potato smell of Phyllanthus reticulatus
wafted over the campsite while we persuaded reluctant tent pegs to penetrate
the hard ground. Tessa's tent took full marks as the small onion like
domes on each end resembled something out of Arabian Knights! However,
during the night hours some tension was created as the banshee howl of
the mine shift change siren echoed over the (slumbering?) campers on the
football field!
As the Nyoni Hills were an hour's drive away we headed out the following
morning stopping en route next to the Tokwe River where we found a couple
of Androstachys johnsonii (ironwood). A really interesting find as Tom
Muller had given Mark a specimen a few days before and it was exciting
to see the dark green heart shaped leaves with white underside and the
young terminal leaflets looking like a pair of tiny cupped hands. As an
aside it was pleasing to note that the mini-soccer machine, on which Tom
Muller challenged the locals to a game, on a previous Tree Soc. visit,
was still in place.
The road wound its way up into the hills passing thickets of Acacia schweinfurthii
well covered with pods and the odd Baobab before stopping a short distance
past an unexpected microwave tower. Moving in and out the rather patchy
Miombo wood¬land we came across another of the Euphorbiaceae family,
this time Alchornea laxiflora which had large rounded leaves and a pronounced
"drip tip". Another feature was the pair of hairs or glands
at the junction of the leaf and petiole. Another new one to me was Cordia
grandicalyx, which sounded impressive, but the name refers to its unusual
calyx and as expected no fruit or flowers could be found.
From our vantage point on the granite whaleback we were able to have a
good look out over the lowveld heading away in the direction of the mine,
some 40 km due west, with the shallow Tokwe River meander¬ing its
way south west through increasingly arid country. Until now the lowveld
temperatures had been kind to us but after fifteen minutes in the full
sun, the idea of lunch in the deep shade was too much to resist. Another
find on the way down was a colony of shrubby Maytenus mossambicensis,
where the clusters of small serrated leaves masked the long red spines,
interesting to look at but bad news for the fingers! More Tabernaemontana
elegans appeared, the mature ones having a surprisingly corky bark and
in a rock crack we noticed the wavy margined leaves of a Ficus tettensis.
Some interesting after lunch finds were Stadmania oppositifolia, one of
the Sapindaceae family with opposite leaves of an almost green lacquer
colour and the more familiar Rhus chirindensis at home in the hilly terrain.
Our slower than normal progress (that's really some¬thing!) was halted
when Tessa emerged down the road clutching an armful of foliage in which
lurked a few leaves with alternate leaflets that we had not yet seen.
Possibly the colour but most likely the long drip tip stimulated the few
to think of Calantica jalbertii. It would have been a shame to have come
all this way and not see it on its home ground.
An exciting but also confusing day with so many specials popping up in
an area that few of us have the opportunity to wander in and we recorded
80 different species, pretty good for an area of about a square kilometre!

SUNDAY 17 APRIL 1994: BANGALA DAM
The plan for the day was to visit Bangala Dam and Linda, with her usual
efficiency, had mapped out our route in, as well as offering alternative
returns.
The dirt road took us from Renco to Musvosvi then eastwards and north
via Bangala Mission to the dam wall, where we were delighted to find an
oasis of green lawns, shady pergolas and spreading trees (Erythrina lysistemon,
Poinciana regis and Ficus lutea, all probably introduced). These attractive
gardens, perched high on the hill slope on the west bank, give a commanding
view of the dam wall and surround the water bailiff’s complex. Unfortunately
this official was away, so we retraced oar steps and took a track below
the bailiff’s house from where we botanised on the hillside and
down¬stream along the Mutirikwe. The left bank of the river was denied
to us because the outlet at the base of the dam wall was open and a great
plume of water arch¬ing from this point, sent a flood downstream,
filling the channel from bank to bank. The intrepid could of course reach
the other side at the risk of a $2 000 fine and a vertiginous crossing
of the Bangala wall and spill¬way. The former deterrent is obviously
not applicable to the locals, one of whom made the crossing bearing a
loaf of bread.
Many familiar species included Acacia nigrescens, Brachystegia glaucescens
and Brachystegia spiciformis, Colophospermum mopane, Ficus abutilifolia,
Kigelia africana, Kirkia acuminata, Ormocarpum trichocarpum. And exciting
new finds were Coffea racemosa, Dombeya kirkii in bloom, Ficus capreifolia
with sandpaper leaves, Holarrhena pubescens, Pteleopsis myrtifolia, Spirostachys
africana, Ximenia caffra var. natalensis, Androstachys johnsonii. Maytenus
mossambicensis, with soft autumn coloured leaves and bright pink fruit
arid Vitex ferruginea subsp. amboniensis with fruit the size of plum tomatoes.
Two-and-a-half hours of work gave us 75 species, by which time the temperature
had soared to the mid-thirties and dehydration and fatigue drove us back
to the garden. Here we lolled in the deep shade of a pergola, eating,
drinking Andy's most welcome iced cokes, dozing, or poring over our botanical
souvenirs till mid-afternoon. Then we returned to the mine – some
via Nyikavanhu to rejoin the main Triangle road at the 42 km peg and the
rest backtracking on the morning's route.
An interesting and rewarding day and wonderful to be with our Mashonaland
counterparts once again. Thank you for inviting us.
Ian and Margaret McCausland
MONDAY 18th APRIL – RENCO MINE
Monday found us ambling in the hills behind the mine workings and with
the changing terrain from rock faces to well wooded gullies, the day was
full of surprises.
The shallow soil pockets on a rock face were home to an exciting find
– an Apocynaceae named Strophanthus kombe (also called the Zambezi
Tail flower). The few remaining obovate leaves covered in stellate hairs
were nothing compared to the pairs of long cylindrical pods tilted upwards
at a rakish angle. Teclea trichocarpa was of the few Rutaceae recorded
and as always meddling fingers damaged the hundreds of tiny pellucid glands
in the trifoliate leaf so producing the characteristic citrus smell.
Another set of unusual green leaves was almost enough to trigger an attack
of arboreal haze but the highly distinctive veining from the base of the
leaves made satisfying identity for Strychnos mitis. We had seen this
the previous day growing with a Berchemia discolor near the mine tavern,
where our seed collecting created great excitement to both children and
imbibers from the nearby bar.
Afternoon meanderings along the riverine fringe of the Garutsime River
produced an interesting mix of more familiar species (at last!) such as
the smooth grey barked Trema orientalis a Ximenia caffra var. natalensis,
easily recognised, as the young leaflets were hairless. Another new one
for the day was Coddia rudis, shrub-like and scattered along the river¬bank.
As the afternoon drew to a close we trundled back to the mine casting
wary looks at the massive bags of specimens which attempted to break free
every few minutes when the Landcruiser vibrated its way over the corrugations.
We had a really fantastic time at Renco Mine and despite the ants that
felt they should also share tent space; the football-pitch was a really
convenient spot (3 loo's and 10 showers!). Very many thanks to the Management
of Renco for arranging our stay.
ANDY MAC
BULAWAYO TREE SOCIETY
With an ample collection of octogenarians, septuagenarians, one infant,
and other folk, the Bulawayo Tree Society proceeded 65 kilometres on the
Harare Road to the home of the Brownlee-Walkers. To counter the coolish
May 1st weather, the warmth of Mr. and Mrs. Brownlee-Walker, whose courtesy
and hospitality made our morning teatime most enjoyable, augmented the
warmth of the sun. The Bulawayo Tree Society had been invited by the Brownlee-Walkers
two years previously, but after many postponements and cancellations the
visit became possible.
At our first stop, we found Acacia rehmanniana, Carissa edulis, and an
old an acquaintance, Carissa bispinosa, and to some of the newer members,
a new discovery Balanites aegyptiaca. This led to a discussion of the
differentiation of Balanites aegyptiaca and Balanites maughamii.
At the next stop on this 15 000 acre cattle farm, we disembarked to be
informed that the farm was first occupied in 1912 and that where we were
standing, evidence had disclosed of a large settlement of indigenous people.
They had been present from the latter part of the 19th to the early part
of the 20th century. It was further pointed out that the present water
supply would not sustain a large population now, corroborating what people
in Bulawayo suspect, that the climate is changing.
Further peregrination along a fence brought our attention to large numbers
of shrubs and Burkea africana, Albizia antunesiana, Combretum molle, Dichrostachys
cinerea, Ziziphus mucronata, two species of Terminalia, Terminalia sericea
and Terminalia brachystemma, and 3 species of Grewia. Several larger specimens
of Albizia amara, Acacia karroo and Acacia robusta, Combretum apiculatum
and Combretum hereroense, Diplorhynchus condylocarpon. Euclea divinorum
and Euclea racemosa, Peltophorum africanum, Combretum hereroense, Rhus
lancea and Rhus tenuinervis along with Parinari curatellifolia, and many
others. Only one Securidaca longipedunculata was seen, isolated Ozoroa
insignis, Pavetta schumanniana, Vitex payos, Piliostigma thonningii, Sclerocarya
birrea and others were encountered. Extended discussion followed concerning
differentiation between Grewia bicolor and Grewia monticola. One comment
was introduced “Grewia bicolor resembles soldiers in line, standing
straight parallel, and at attention.” The Terminalia discussion
centred around the decurrent leaf base of Terminalia brachystemma.
The fence prevented anyone from getting lost, an occurrence not unheard
of in our Society. We gradually meandered back, having segregated into
small groups, in which we remained to find shady areas for lunch. The
tallest Grewia monticola and Elaeodendron matabelicum tree that our group
had ever encountered – 6 to 8 meters – a Kirkia acuminata
and many others generated our shade.
The best was yet to come, for after driving to another area, the savannah-like
grassland was pocketed by verdant tree growth. Questioning the case of
this more luxuriant growth, we were informed that this might have been
initiated by termitaria and/or a higher water table. Investigation of
these pockets revealed a winter Cassia (Senna singueana) about to burst
into bloom, Lannea discolor, a Clerodendrum glabrum taller than we have
previously seen (6 to 8 meters), a Kirkia acuminata, and many others.
Crossing a small, dry rivulet, we approached a large, heavily fruited
Gardenia volkensii, which yielded enough material for our members to seed
their gardens. Further search revealed a Bolusanthus speciosus which was
large, high, rounded and with pendent branches. Too bad we did not bring
our camera. Then came this writer’s most important discovery –
an Albizia harveyi, too tall to recover any fruit or leaves (however,
someone directed me to a source in Bulawayo). My arrival just before nightfall
necessitated a morning sojourn to capture some leaves and pods for microscopic
study.
A location was found for afternoon tea and for tabulation and discussion
of species.
The intensity and mental alacrity of our group could not be dampened by
the presence of what we in the United States of America would term buffalo
chips . In fact, due to this retained intensity, even at closing time,
these "chips" were not even noticed.
This illustrates why I feel this group must be the most portentous in
Zimbabwe.
Oh yes, we came across a moulted mamba skin, saw a soaring Bateleur eagle,
spied a diminutive Psydrax livida almost hidden behind a rock, marvelled
at the afternoon sun shining on fruit of Russet bush willow. Wondered
in amazement why the massive number of Albizia amara legumes did not overpopulate
the universe, and left the Brownlee-Walker’s ranch at peace with
the world.
May we return – please?

THORA’S HERBAL REMEDIES
1. Soapwort, Bouncing Bet, Australian Creeping phlox – Saponaria
officinalis
Mention made of the saponins in Zanha africana in the last issue of Tree
Life, brings to mind that wonderful cleansing plant, which is very invasive
in the Garden. Instead of cursing it, use it and bless it for it’s
many and varied uses.
Soapwort or Bouncing Bet (so called, because the women in times past used
to bounce up and down doing their weekly washing) grows easily in any
soil and throughout the summer sends up dense heads of pretty pink phlox-like
flowers in either single or double form.
The roots, stems, leaves and flowers can be put into a large pot, covered
with water and brought to the boil for 15 minutes. The resultant brew
should be left to cool and then strained. The soapy green liquid can then
be frothed up and used. We were present when Ken’s cousin did her
weekly washing with It and her bed linen and towels came out beautifully
clean and wonderfully soft. Her hands too benefited from the experience
as soapwort has a remarkable soothing and softening action on the skin,
but of course there are some people with very sensitive and allergic skins
so a simple skin test may be necessary at first.
The brew cleanses everything; linen, woollen materials before dyeing,
fabrics with delicate colours, precious woven hangings and tapestries.
It is excellent for cleaning carpets.
Saponaria is also the homeopathic remedy pre¬scribed in the treatment
of all skin ailments – scabbing, acne, pimples, urticaria, rheumatism
and gout. Arab doctors prescribed it for ulcers and leprosy.
Two cups of soapwort leaves and flowers boiled in a litre of water for
a minute or two is a good wash for rashes, sunburn and eczema. The same
brew can be used as a dab on lotion for cuts, scrapes and grazes. The
deep soothing action will clean a wound and promote healing.
This same brew can also be used as a hair rinse and conditioner especially
for dry, brittle, over-permed and unmanageable hair. Wash the hair in
the normal way, rinse and then soak the hair in a soapwort brew, massaging
it into the scalp for 7-8 minutes. Rinse and dry and you'll notice a remarkable
difference.
Used in the bath it soothes, smoothes and softens the skin. Try it after
a hot day in the sun. Dogs, cats and horses can be bathed with the brew
to clear up eczema and to keep their hair/fur soft, silky and shiny.
Houseplants can be sprayed with it to keep them free of dust and fungus
attacks.
Plant lice and mildew vanish with a weekly wash.
When the plants in the garden begin to get straggly and untidy, cut them
right back and place the cuttings on the compost heap. They break down
very quickly.
2. Dicerocaryum zanguebarium
The name is derived, from the Greek words meaning two-horned fruit from
Zanzibar.
This is a common trailing annual found growing in the grass of our sandveld.
It has a thick woody rootstock, lobed leaves which grow opposite each
other and very pretty pink-mauve tubular foxglove-like flowers. The fruit
is a flattened disc with two hard prongs or spines on the upper surface.
They look like boot protectors or studs and the spines are a good means
of dispersal.
The leaves, flowers, stems and roots soaked for 24 hours or boiled in
water make an excellent soap substitute or hair shampoo used by the Africans.
The liquid is used to baths babies suffering from measles and to facilitate
a difficult birth in livestock.
The leaves are edible and are cooked like spinach.
THORA HARTLEY
NYARUPINDA CATCHMENT
The Scene
Everyone is talking about water, day by day there is less to share out
for irrigation. The bush has dried up, there are birds visiting the garden
that were not seen last year, Heuglin's Robins have been very loudly melodious
at the streak of dawn. They have taken a long time to find the water in
this garden on a stony hillside.
April 27th 1994
This day will always be remembered because it was spent with 16 children
and a few grownups at Muzunga Dam SS. Ranch, Raffingora. The dam, teeming
with life, is on the Madziwe River in the Manyame catchment.
The day's programme began with a run, after breakfast there was a walk
to see rock paintings. Andy Bone, a well-known artist, spoke about rock
art and the San artists.
On returning to the Bush Camp we sketched from memory two human figures
and one animal bushman style, which meant that rubbing out was not allowed.
After inspecting all the pictures Andy said all of us had made the heads
too big, this exercise proved how difficult it was to draw what we had
seen. At the rock art site we saw three short red parallel lines among
the figures in the frieze, those are said to symbolise rain. These lines
are not uncommon, who has seen them?
Vitex payos on the kopjies bore ripe brown fruit, when told it was Chocolate
Berry tree the children exclaimed yummy this changed to yuck when they
tasted the fruit.
After lunch and a rest some children helped me to arrange a Nature Study
Display of the following items. Fruits of Combretum hereroense and Acacia
albida Faidherbia albida); two cylinders of wood from fire-resistant Indigenous
trees to show their thick bark e.g. Acacia amythethophylla and Parinari
curatellifolia; nests of a Penduline Tit and a tailor bird be it of a
warbler, Prinia or Cisticola. A Scimitar-billed Wood hoopoe (recently
found dead in the garden); a Mantis nest on Swamp Couch Grass; a Carder
bee, Serapista sp. whose body is black and white, beside its woolly nest;
'ear feathers' from a Scops Owl, accidentally killed. Pieces of wood bearing
a white and a small brilliant orange-coloured bracket fungus. Regarding
fungi it is necessary to digress here to pass on some information, which
may interest readers who went to school a long tine ago. "Fungi are
a group of organisms that were at one time classified in the Plant Kingdom
(and still are by some botanists). Most mycologists now place them in
a separate Kingdom, Mycota … they differ from plants in that they
have neither chlorophyll nor a root system". This information comes
from C. Sharp's article Edible and Poisonous Fungi in Zimbabwe, "Science
News", July/August 1983.
There was another fungus exhibit, a portion of fungus garden from a termitarium
together with a photograph of a partially demolished termite mound showing
the 'garden' in situ. A Raffia Palm fruit and a photo of a Bark Spider
completed the Exhibit.
The Quiz
It was a challenge planning the Quiz for the children who attended the
Bush Camp because their ages ranged from 8-14 years. Inspiration came
from Rhodesian Knowledge (which began in 1976) and from Bush beat a supplement
to Zimbabwe Wildlife and resulted in 16 questions that totalled 36 points.
The best scores were 27 and 26 points so it was quite difficult for them
but not gloomy because there were some fun questions. On the question
paper there was a column for corrections and the answers were put on the
blackboard so as to satisfy the keen children and inform the others.
What was the name of the trees, which grew beside the "great Grey-green
greasy Limpopo River?” What is another name for these trees?”
The head of an animal is the symbol of the Wildlife Society of Zimbabwe,
what is it, what is the message under it? What is a badminton bird? Name
the pair of animals running through the centre of Harare. Name four of
the sculptured animals beside the Queen Victoria Museum in Harare, what
food is eaten by each of them?
When bats excrete they hang by their thumb claws to avoid polluting themselves,
true or false? Herpetology is the study of a certain groups of animals,
what are they? The answer was reptiles and amphibians, in the discussion
during corrections the children, quite rightly, included dinosaurs.
After Tea and lots of Biscuits
A stroll to the dam, a few metres from the camp, to look for aquatic insects
rounded off the day. This was interesting because the children had received
photo¬copied illustrations of Insects at the Water's Edge, which accompanied
an article by EH Pinhey, in Wild Rhodesia No. 8. The 'star’ insect
found was a Whirligig Beetle, which writes on the water and has two eyes
to see above the surface and two eyes keeping watch below. A magnifying
glass provided a lot of entertainment, and we saw parasites on these beetles.
Feretia•aeruginescens
This tree is fruiting now and is very decorative with crimson berries
closely spaced along the branches. The fruit is this tree's label; it
has a white circular scar edged with four or five black points, the remains
of the calyx.
Travellers to Kariba have noticed Feretia close to the road about 20 km
from Makuti on the escarpment side.
