Though there are thus slight differences in the composition of 

 Midland bush as it occurs in different localities, yet its general 

 oecological character is the same, and this will be summed up 

 later. 



(2) Smaller Scattered Bushes and Rocky Stream Bush. 



A glance at the map will show that there are numerous 

 small patches of bush scattered over the high veld region 

 (e.g. on the Town Hill). The larger bushes also are very 

 ragged in appearance. Clearings have been made which 

 penetrate into the very centre of the bush. Scattered patches 

 remain in the neighbourhood of the larger bushes^ and isolated 

 stumps of trees may be found between them. These small 

 bushes are also common near the sources of the streams, and 

 frequently fill the higher stream valleys. 



Their character may be summed up and described in a 

 sentence. They are similar in every respect to the outer 

 margin of the bush proper. This fact, together with the way 

 in which they occur and are distributed, points to the con- 

 clusion that they are the remains of a forest which formerly 

 covered the whole area over which they are now scattered. 

 They are now found in the ravines and less accessible places, 

 because there naturally the influence of man has been less 

 felt. 



These bushes are more open and irregular than the larger 

 type. More light penetrates, and the ti-ees found in this kind 

 of bush are all more or less lio-ht-demanding-. The following- 

 make up the type : 



Rauwolffia natalensis, Combretum kraussii, Ficus 

 capensis, F. natalensis, Rhamnus prinoides, Celtis 

 kraussiana, Trema bracteolata, Grrewia lasiocarpa, 

 (t. occidentalis, G. caffra, Buddleia salvifefolia, 

 Vitis cuneata and other species, but not Y. capensis, 

 Nuxia floribunda, Calodendron capense, Cussonia 

 spicata, Xymalos monospora (sometimes). 



Seeing that more light penetrates through this type of
