as Port Elizabeth. This, of course, does not mean that elements 
characteristic of other regions are absent from it; in fact, here 
and there, more or less large associations which seem to be foreign 
to the region occur, for instance, associations of forest plants and 
Karroo plants, as pointed out already. From the heights east of 
the Gamtoos River to the beginning of the Van Stadens Gorge we 
travelled through typical South-Eastern grass country with scat- 
tered bush such as we find near Bathurst, south of Grahamstown. 
The last point I would like to refer to is this. On a previous 
trip I had confirmed one of Ecklon’s observations—unfortunately 
overlooked by Bolus and others—that karroid vegetation 
stretches from Port Elizabeth to the mouth of the Sundays River, 
thus forming a broad wedge between the South-Eastern and 
South-Western Regions. I noticed that this wedge consists, near 
Coega, partly of low karroid shrublets (including Pentzia vir- 
gata). On the trip here dealt with I travelled from Uitenhage 
to Coega, and I ascertained that there are extensive flats on this 
road covered with these karroid shrublets. Karroid vegetation is 
also found all over the hill called the ‘‘Coega Kop,” which is 
composed of Table Mountain sandstone, another of the numerous 
instances which we have of the secondary influence of geological 
formation on the distribution of plants in South Africa.
