The second series of forests visited run along the sansa 
boundary of the Mawokota District. They commence at.about 
mile 16 on the Kampala-Mubendi Road, and continue to about 
mile 26, but here deviate somewhat from the main road. The 
sections visited are known as Balisangakibugo, Tiriulire, Mwen- 
gizanyagi, Nakatumba, and Nakinyika, and are drained by the

of the Great Lake into the river

n general character. they do not vary to any considerable 
extent from those strictly in the Victoria Nyanza region. The 
same undergrowth is met with—Dracaena, Amomum, Cyperus, 
lanes, and in parts a low shrub. This undergrowth is, 
generally speaking, not difficult to penetrate, and only when 
nearing the outskirts of the forest is a more tangled and denser 
vegetation encountered. This consists first of a thick shrubby 
erowth, then of a mixture of Elephant Grass (Pennisetum pur- 
pureum), prickly se srr —— spp., and Cucurbitaceae.

The forest trees are, ta nythi si more striking here than in 
the other series of forests visited. The tall white-barked trees 
with Usnea-like lichens hanging from their branches are very 
beautiful; likewise the giant ‘‘ Mwafu,’’ Canarium Schwein- 
furthii, with its massive arms laden with the Bird’s Nest fern 
(Asplenium Nidus), Platycerium sp., Polypodiums, and Orchids. 
hoeniz reclinata enjoys a wide distribution both in the sur- 
rounding country and in these forests. 
The fungus-flora is more or less identical with that of the 
forests i in Kiagwe and Busiro, round the lake, since the forests 
are in most respects alike. Of the Polyporaceae the most 
abundant representative seen was Polystictus aratus. This 
species was plentiful on stout fallen branches and on dead 
branches still adhering to the tree. Sterewm lobatum was widely 
ispersed, and the forms here were larger than any previously 
gathered. Species of Xylaria were also very numerous, including 
some very stout forms of X. grammica. The following fungi
