rainfall, probably not less, on an average, than an annual fall of 
50. inches. Rauwolfia natalensis is common in this stretch of 
country, and at Palmaryville (2200 feet) I came across a specimen 
of Oncoba spinosa (identified by the Govt. Botanist 
On the road to Shewass from Palmaryville, Pygeum ‘africanum and 
Brachylaena discolor were growing on the open veld at 2300 feet. 
The occurrence of these Sata in this district serves to indicate 
the moist nature of the clim 
At Shewass (3400-3500 feet) there is a dense forest which runs 
east and west and has an eastern exposure. The elevation of the 
bush is from 3200-3600 feet and the trees are from 50-75 feet 
high. This forest differs entirely from the yellow-wood forests of 
the Drakensberg; the number of species occurring in it is 
comparatively small, and several of them are, I think, unrecorded 
for the Transvaal. The principal trees are Albizzia fastigiata* 
(no. 4867) and Pde i ae Magalis-montana (no. 4824), whilst 
others noted inclu e following: Trichilia emetica, Rhus 
laevigata, Combretum "Kra ‘aussii (Vaterlands Wilge), C. holosericeum* 
(no. 4868), Anthocleista cambesiaca (common) and a species of Ficus 
(no. 4875). The Chrysophyllum attains a height of 30-40 feet, 
whilst Combretum holosericeum reaches 50 feet with a trunk 
18 inches in diameter, and has a bark which resembles that of 
Curtisia. Albizzia fastigiata*, Reith ably the “Flat Crown” 
of Natal, grows to a height of 50 feet, with a bole of 20 feet and a 
diameter of 2 feet. The natural regeneration of this species is 
very good. Other trees noted in the bush were Acacia ataxacantha, 
Brachylaena discolor, Maesa rufescens, Nuxia floribunda, and the 
cabbage-wood, whilst the following were collected : Neumannia 
theaeformis* (no. 4872), Rawsonia lucida (no. 4869), Pterocelastrus 
sp. (no. ween oo fastigiata* (no. 4867), Combretum holo- 
ericeum* (no. 4868), Eugenia spp. (nos. 4826 and 4876) Grumilea 
sp. (no. 4870), Chrysophullum Magalis-montuna (no. 4824), Landol- 
phia sp. (no. 4874), Bridelia micrantha (no. 4823), and a species of 
Ficus (no. 4875). 
Parinarium Mobola and Pterocarpus angolensis (in flower) were 
seen round the edges of the bush on the slopes of the hills. 
Throughout the forest the Landolphia vine (no. 4874) is common, 
climbing right into the crowns of the trees. Though rather early 
in the season, I collected a small quantity of rubber which appears 
to be of excellent quality. I found this vine at the Pipiti Falls 
and it also occurs at Tengi ve, Makundi Nek, ee i sen, 
Wuba and many other places in the N.E. Transvaal. It orow 
mainly in forest composed of Chrysophyllum and Albizzia. The 
Bavenda name of the rubber is “ Mavungo. 
On the mountain ridge forming the northern boundary of the 
Shewass bush and fusing due south is a normal forest, similar to 
the Houtbosch or the Drakensberg. There is, however, no 
undergrowth of shrubs in the forest, only grass being found beneath 
the trees, yet the canopy is continuous though not so dense as that 
of the Drakensberg forest. The lower and upper ridges are
