5,000 feet; a restiaceous plant, one of the dominant species; Pcn- 

 taschistis colorata, growing in scattered clumps at 5,000 feet ; 

 Ehrharta rauiosa, common at 5,000 feet, and one of the dominant 

 species; Lcncadendron glutinosuni, a sub-prostrate plant, fre- 

 quent at S,ooo feet ; Rafnia cuncifolia, of which a few specimens 

 were seen at 5,000 feet; Tetraria involucrata is very common at 

 4,500 to 5,000 feet, and forms one of the features of the vegeta- 

 tion, as it stands conspicuously above the grasses, restios, and other 

 sedges. The slopes just described were exceptionally dry. 



Beyond the kopjes forming the south-east boundary of 

 Sneeuwgat is a sandy valley, down which an annual stream runs. 

 The soil is composed of decomposed sandstone, forming white 

 sand. Rocks or large stones are almost quite absent, especially 

 in the lower portions. In a marshy patch in this valley was a 

 dense social growth of W'atsonia sp. In the upper reaches of the 

 valley (near the W^itzenbergen) the dominant species is No. 53 

 (a restiaceous plant), while lower down this is ousted by No. 54 

 (a restiaceous plant), which dominates. Growing among No. 53 

 are isolated p^itches oi Daiitlioiiia laiiofa; ^ispalathiis s/^., forming 

 cushions on the ground; Lessertia pulchra; Schizodutni inflexnm; 

 Ixia scariosa var. ; Sphcnogyne anetJiifolia, a prostrate plant; and 

 S. iiitdicaiilis, a compact shrub, with underground stems. 



The Great Winterhoek may be ascended by way of a steep 

 narrow ravine, which takes one almost to the summit. This 

 ravine is very densely covered with Ehrliarta raiuosa, so much so 

 that the ascent is made somewhat difficult. Not much else was 

 growing in the ravine except a few plants (Nciiiesia diffusa, Geis- 

 sorhica gcmissata) on the wet rocks at the sides. On a clifif face 

 at the head of the ravine are fine specimens of Proiea Dykei. 

 This beautiful protea is now known from four mountain peaks, 

 all above 5,000 feet altitude, z'ia., the Coxcombe Mountains 

 (Uitenhage); the Zwartbergen, near Oudtshoorn; the Somerset 

 West Sneeuwkop ; and the Great Winterhoek. Its habitat, as far 

 as I am able to gather, is always the same — on rock faces. The 

 summit of the Winterhoek itself is very rocky and stony, Init 

 where soil is deposited it is covered with Restio sp. NanoUron 

 capcnse, a small liliaceous plant, is found among the rocks, and 

 forms small cushions on the ground. This is another of the 

 species confined to high mountain summits. Bolus first found it 

 on the Little Winterhoek, and Marloth later collected it on the 

 summit of the Matroosberg. Other flowering plants were rare, and 

 the following list represents all the species found : — Lacluuca pciii- 

 cillata, growing on clifT faces; Ccclidimn rosenm, a bush one to 

 two feet high ; Aster bcllioides, a plant with woolly leaves (also 

 found by Marloth and myself on the summit of the Matroos- 

 berg) ; Biilbiiic sp., which was copimon in Sneeuwgat at 4,000 feet ; 

 Erica sp.; Mitraltia crassifolia; and Selago sp. 



The total number of species collected on the two trips is 245, 

 as follows: — Dicotyledons, 173; monocotyledons, y2. Proportion
