A COLLECTING TRIP TO FRENCH HOEK. 4^1 



a more varied flora ; 60.29 per cent, of the total number of species 

 recorded were collected on Table Mountain Sandstone, only 

 3f.64 per cent, on the Malmesbury Beds, and 13.13 per cent, 

 on the Recent Deposits in the valley itself. Many of the species 

 were only found growing on the one formation. Confined to 

 the Table Mountain Sandstone were such plants as Anemone 

 capensis, Knozvltonia rigida, Ranunculus pinnatiis, Pelafgonium 

 ovale, var.. Zygophyllum sessilifolium. Meseinbrianthcnutm monta- 

 num, M. clegaiis. Aloe hccmathifolia, Tliamnochoriits cernuus, etc. 

 The following species from numerous others were only collected 

 on the Malmesbury Beds, tv'r., Silene capensis. Pelargonium bar- 

 batitni, Lintt'in quadrifoliuyn, L. africanum, Anaplireninni argen- 

 temn, Mefalasia nmricata, Sebcea exacoides, Cyanella lutea, Alpe 

 plicatilis, etc. Among the plants only found on the Recent 

 Deposits, and which were not found on either of the above two 

 formations may be mentioned Harveya laxiflora, Lencospermum 

 hypophyllum, Selago spuria, Serruria gracilis. Frotea lorea, etc., 

 A certain number of species were found, however, to occur uu 

 more than one formation, as for example Pelargonium myrrlii- 

 fuiiinn. Borbomia parz'i flora, Psoralea decumbcns, Drosera tri- 

 nerz'ia, Aspalathus heterophylla, Corymbium scabrinn. Erica 

 dcnficiilafa. E. cxsurgens, tVacho'.dorfia paiiicitlafa. Eapeyrousia 

 cor\)nbosa, etc., on the Table Mountain Sandstone and the 

 Malmesbury Beds. Pterygodium catholicum was the only species 

 I found common to the Table Mountain Sandstone and the Recent 

 deposits. Pelargonium myrrhifolium, RJius angitstifolia, Lenco- 

 spermum lineare, Cryptadenia uni flora, Satyrium corii folium, S. 

 nmrginatiim, Cyanella lutea, Dilatris corymbosa were the only 

 species collected on the Malmesbury Beds and the Recent 

 Deposits. There is no single species, as I judge from my collec- 

 tion, which is common to the three formations. Thus the flora 

 of the mountains above 1,500 ft. is sharply divided from that of 

 the valley, with outlying species from each encroaching short 

 distances into the Malmesbury formaUon. 



Regarding the flora as a whole, we find that the bulk of the 

 species are either woody shrubs, bushes, or trees ; plants of this 

 habit compose 45.07 per cent, of the total flora; herbs or herba- 

 ceous plants make up 38.20 per cent. ; acaulescent plants, prostrate 

 plants, or scramblers, compose 10.44 per cent, of the flora. 

 Annuals are represented by 20 species (or 5.97 per cent.); 

 succulents by 12 species (or 3.58 per cent.) ; parasites by four 

 species (or 1.19 per cent.) ; and insectivorous plants are 

 represented by three species of Drosera, and a species of Utricu- 

 larici (or i . 19 per cent.). Many plants, such as Pelargonium 

 flavum, Drosera cistiflora, Gazania pinnafa, Disa racemosa, 

 Satyrium candicans, Gladiolus spp., etc., possess underground 

 stems or thickened roots, and these comprise 17.61 ])er cent, of 

 the total number of species. The vegetation is of a true xero 

 phytic type, and a detailed study of the leaves yields some 

 interesting results. The bulk of the species have simple glabrous
