2. PROTEA VELB. 



The Thorn Veld, where Acacia species grow isolated 

 among the low-veld grasses, is absent from the Drakensberg. 

 It reaches a fair altitude (about 4000 ft.) at the heads of the 

 great main river-valleys, but it is not a mountain type. Tlie 

 thorn-trees are adapted rather to the dry, hot valley climate. 

 Instead of the Thorn Veld we have another type on the 

 Drakensberg, somewhat like it in certain features, but, in 

 other respects, differing considerably^ viz. the Protea 

 Veld. 



The species of Proteacete in it are not numerous. One 

 of them, Protea hirta, is found at lower altitudes also, 

 though not abundantly. The others ai'e Protea abyssinica, 

 P. lanceolata, P. roupellias, P. flanagani, P, multe- 

 bracteata, P. simplex, P. subvestita, Leucospermum 

 gerrardi. These are all small trees which, when in floAver, 

 are very handsome and the Protea associations may be con- 

 ■sidered the most oi-namental occurring in Natal. The trees 

 grow isolated like the thorn-trees, dotted over large areas 

 ■of the veld. They are all xerophytic forms and grow fully 

 exposed to the various adverse factors of the mountain 

 .climate. The veld in which they grow is of the tussock type, 

 already described, with very unstable soil conditions. In this
