systoins are usually fibrous and well developed, and extend 

 into the fissures to obtain tlie necessary moisture. 



The following species are characteristic : Mnraltia saxi- 

 cola, Crassula several species, Helichrysum fnlg-iduni, 

 H. fulgidum var. nanuni, H. Sutherland i, II.

 Notholfena eckloniana, Cheilanthes hirta, Mohria

(B) Shelteked Chomophytes. 



In this type we have much deeper, firmer, and moister 

 soil in the crevices, and the plants are sheltered and conse- 

 c^uently gi-ow more luxuriantly. They are more massed 

 together and are of a more mesophytic type.' Bulbous forms 

 are characteristic, and often the root system of these consists 

 of long, tough fibres. The species composing this class 

 probably vary considerably in different localities, and further 

 exploration will add to their numbers. Many of the plants 

 included in the list of those belonging to the Pynbosch for- 

 mation are sheltered chomophytes. The following is a list 

 of species belonging to this class: Sutherlandia fru- 

 tescens, Helichrysum tenuifolium, Aster filifolius, 

 Gerbera sp., Stcebe cinerea, Geum capense, Rumex 

 woodii, Gruthriea capensis, Selago flanagani, Zalu-
