and nigriceps). Amongst the commoner trees of the open bush of this 
neighbourhood were Acacia caffra, an Albizzia, am Odina, Dalbergia 
melanoxrylon, Bauhinia reticulata, Tamarindus indicus, a Combretum, Strychnos 
Burtoni, a Millettia, and Lonchocarpus violaceus. Few of them reached, 
I should say, more than 40 feet in height, while in many parts they were 
much lower, which may be taken to apply to nearly all the better-grown 
bush of those parts of the lowlands through which I have passed. The 
common shrubs included Anona senegalensis, Peltophorum africanum (perhaps 
better placed amongst the trees), Vangueria edulis, and Flacourtia hirtiuscula. 
I also paid a short visit to the Madanda rubber-forests. The open woods, 
which extend with only an occasional slight break all the way from Chiba- 
bava to Arucate, the collecting station on the edge of the rubber-forests, were 
varied and for the most part composed of much the same species as I had 
met with round the former place. Acacia caffra and especially a Combretum 
were particularly abundant, though //olarrhena febrifuga also occurred in 
numbers, its great masses of white blossom making quite a flower-garden of 
the woods. However, eight or nine miles south of Bimba I was surprised to 
find intermixed with the commoner species of the lowlands a number of such 
high-veldt species as Ormosia angolensis, Conopharyngia elegans, and Gardenia | 
asperula, these three all in flower. I also passed a number of Pterocarpus 
angolensis, the first seen since leaving Chirinda. Approaching Arucate the 
country became more broken up into hollows, likely to be swampy in the rains, 
and dried-up pools appeared, while the bush in general became smaller and 
more scattered. That immediately round the station at Arucate chiefly 
consists of Brachystegia, mingled, especially on the large ant-heaps that abound 
there, with а Grewia (G. madandensis), a Vitex, and other trees and shrubs. 
The soil is light grey and very sandy, both here and through a great part of 
the aetual rubber-forests. 
These forests are, at all events in Butiro's country, simply very dense bush 
averaging little more than 25 feet in height, and composed largely of such 
low-growin g trees as Crossopterya Kotschyana and Erythroeylon emarginatum, 
the whole being bound together with a tangle of woody climbers such as 
Landolphia Катки, here exceedingly abundant, Secamone zambesiaca, a 
Landolphia-like Salacia, and various Anonaceous plants, An occasional 
slightly larger tree, such as Monodora Junodi, projects above the general 
level. I found a coffee, probably identical with that which occurs in con- 
siderable quantity on the Juababa stream (which flows into the Umswirizwi 
from the south), and grows, both wild and cultivated, on portions of the 
coast. I was informed that, though there is a comparatively small area of 
larger forest in Makupi’s country, what I saw was typieal of the whole of these 
rubber-forests. 
On my return to Chibabava (elevation about 400 feet) I pushed on towards 
Beira, A few miles out we passed some fine pools and а certain amount of
