(C) Shade Chomophytes. 



This type differs from the last chiefly in the deHcieiicy of 

 light. Flowering plants are poorly represented, while mosses 

 and ferns are more abundant and characteristic. The greater 

 ^shelter leads to greater atmospheric humidity, and the plants 

 are therefore of a distinctly mesophilous type. It is not 

 always possible to separate shade chomophytes froui the 

 hydrophilous, but the latter are not necessarily shaded. 



The following are characteristic species : 



Flowering plants. — Streptocarpus pusilla, S. spp., 

 Nemesia foetens var. latifolia, N. flanagani, Plec- 

 tranthus sp., Piperomia reflexa, Wahlenbergia 

 montana, and seedlings of other plants which do not 

 commonly survive. 



Pteridophyta. — Ceterach cordatum, Doryopteris 

 concolor, Adiantopsis capensis, Athyrium scandi- 

 cinum, Selaginella depressa. 



Bryophyta. — Fissidens taxifolius {L.) Hedic, F. 

 bryoides Hedw., Calypogeia bidentata Nees., Weisia 

 viridula L., Weisia sp. iiov. (W. bewsii Sim. MSS.), 

 Weisia sp. (mixed with last mentioned, but different), 

 Bryum bimum 8chreh., Rhodobryum syntrichoides 

 (C. M.) Par., Encalypta sp., Brachy thecium sp., Fim- 

 briaria marginata Nees., Lejeunea flava L., Lepi- 

 dozia sp. 



(D) Hydrophilous Chomophytes. 



The habitat here is constantly wet. Innumerable stream- 

 lets form a network over the faces of the cliffs and the sides 

 of the ravines. The amount of water in them varies greatly. 



During the dry season they may dry up altogether, but
