Plants found 'hi the District of Uitenhage. 359 



spots with a dense sward of grass and herbaceous plants, in 

 other places it abounds with valleys and glens, shaded by 

 woods. The soil consists of loam and sand, and on some 

 spots, particularly in and near the woods, it is mixed' with a rich 

 vegetable mould. Here the Flora appears in peculiar forms. 



B. The hills in the vicinity of Uitenhage, and between the 

 Zwartkop and Sunday Rivers, from 200 to 800 feet high. 

 The soil, generally, is a modification of what is here called 

 Karroo soil; on some spots it is calcareous, whilst in others 

 sandstone is found. This country is for the most part covered 

 with impenetrable biush-wood, which grows generally to the 

 height of from 15 to twenty feet. The forms of the- plants 

 found here differ entirely from those at the Adow, and have 

 no resemblance to the forms peculiar to the vicinity of the 

 Gape. 



C. The fields of Zwartkops River, at the height of from 20 

 to 100 feet. Here the soil consists of loam and sand; and, 

 with the exception of a few forms peculiar to that country, 

 the rest are similar to those at- the AdOw. 



D. The banks of Zwartkop and' Sunday Rivers. These 

 are generally covered with trees and shrubs, and in the bed of 

 the river many plants are found, which have been carried down 

 the stream from the Winterhoek and other mountains. 



E. The sea-shore of Algoa Bay, from the mouth of Sunday's 

 River to Cape Recief. 



This country comprises downs, and also maritime soil. 

 The plants found here are generally spread all along the whole 

 of the East coast of the Colony. 



F. Plains under the mountains of Winterhoek, Van Staade 

 River, and the hills near Port Elizabeth. The soil in some 

 spots is sandy, mixed with the remains of heath, &c. in others 

 stony and pebbly, and in a few gravelly, from a height of 200 

 to 500 feet. Here are found the same genera which grow in 

 the vicinity of the Gape, viz. : Erica, Restio, Passerina, etc. ; 

 and all the plants are quite different from those found at the 

 before-mentioned stations. 



G. The mountains at Van Staaden's River, from 500 to 

 2500 feet in height. Here grow the same genera which are 

 found 'on the mountains near the Cape. 



H. Hills and forest of Krakakamma. 



I. Zuureberg. 



On taking a cursory view of the disappearance of the one 

 Flora, and the appearance of the other, it seems that the "Win- 

 terhoek's mountains forms the limits of what may be called 

 the Cape Flora, and which distinguishes. itself so much by its 

 representatives Protea, Erica, etc. ; whilst that by which it is 

 supplanted may be called the Flora of Caffraria. In it ap- 

 pears several tropical forms ; for instance, Schotia, Cassia,
