by the Cafirs. Manihot Glaziovii, Ceara rubber tree, has been 
introduced in general to this province, but not a success. The 
same fault to be found here as in our colonies. It is planted 
in the open ground instead of in forest shelter. It is a forest 
tree, so must have treatment according to its requirements. 
Manihot utilissima, Cassava Manioca, root valuable as food 
product, largely grown in the light, sandy soil, and suits the 
natives, as they give it no attention during the season. 
UrTICACEH.—Celtis Kraussiana, common tree. Z'rema 
bracteolata, common tree; wood produces good charcoal. 
Chetachme aristata, common tree. Cannabis sativa, found in 
open ground. Ficus cordata, very abundant. Urtica urens, 
common. 
I have now reached a stage on my list that causes me to 
halt, before I enter upon the MonocotyLepons. Taking 
the OrcHIDE, and those that follow—I have to see a wet 
season before I can describe those that are to be found within 
this limit. The grasses alone will require a paper to describe 
them, being so numerous, and I have many yet to work out. 
There are a good many plants I have not given, as I am 
uncertain about them, and therefore must have them classified 
before I can place them on record.
