A SUMMAEY OF THE DISTRIBUTION OF THE GENEEA OF 
SOUTH AFRICAN FLOWERING PLANTS. 
(With Special Reference to those found in the Divisions of 
ultenhage and port elizabeth.) 
By S. ScHr)NLAND. 
Introductory Remarks. 
I have often felt the need of a concise account of the distribution of the 
genera of Phanerogams occurring in South Africa. I felt this need 
especially when writing an account of the Flora of Uitenhage and Port 
Elizabeth, which is nearing completion. As such a summary, based on 
recent data, was not available, there was nothing left but to prepare it 
myself. It was suggested to me that it might also be of use to other 
botanists, and I, therefore, offer it for publication. 
It has been my endeavour to show as much as possible the general trend 
of distribution rather than give the exact area of each genus. Moreover, 
large parts of South Africa are so incompletely known botanically that a 
more detailed account would in many cases have given a wrong impression. 
However, where details are given, they may be taken to be as accurate as 
available records, checked by my own personal knowledge, have enabled me 
to make them. The treatment of the genera in different families is some- 
what uneven. This is due to various causes. In some large orders references 
to more detailed accounts are readily available, while in others records 
are very meagre ; but, above all, it has been my aim to focus the whole 
account on the Flora of Port Elizabeth and Uitenhage, which in many cases 
actually or approximately forms the boundary of genera, while in others 
it marks the area where the full force of the genera spreading eastwards 
from the South-West and of others spreading from the East to the West along 
the southern coast belt is broken. It will be noticed that few genera 
of fairly general distribution in South Africa are absent from it. Orders 
and genera not coming near this area were only dealt with for complete- 
ness' sake. Some interesting points which have disclosed themselves while 
preparing this paper will be dealt with in the account of the Flora of 
Uitenhage and Port Elizabeth, which I hope to be able to submit to the
