SOME EAST AFRICAN BUTTERFLIES

In this article only those trees and plants which are con- 
spicuous by their flowers, leaves, or habit of growth have been 
mentioned, and no account has been taken of cultivated plants 
with the one exception of those two mentioned as growing at 
Simba Station. To mention all the trees and plants to be seen 
near the railway would require a very large volume. The obj ect 
of the writer has been to try to show the large variety of plants 
and trees which may be seen by any observant person when 
travelling on the Uganda Railway.

Specific names have only been given in cases where specimens 
have been identified at the Royal Botanical Gardens, Kew, 
or have been identified in the ‘ Flora of Tropical Africa,’ or 
Engler’s ‘ Flora of German East Africa.’

evil or promote peace. The Swahili name is 4 Tunguja,’ and 
this name is derived from ‘ Tungu,’ which means a whitlow, 
because it is believed that a poultice made of the fresh fruit 
will reduce the swelling and alleviate the pain. — Editor.

East Africa, from the standpoint of zoology, belongs to the 
Ethiopian region, which comprises all Africa south of the

is very distinct, and the number of butterflies, at any rate which 
range beyond its borders, is very small, whilst whole sections
