Eastern Scrub. 



This occurs in kloofs and shady slopes not higher than 

 7,000 feet. 



On the lower edge of the formation CJuytia sp. ( ? na- 

 talensis) often occurs. On fairly dry gravelly situations 

 Myrslne africana is often dominant. Sometimes Rhus 

 sp. { ? miicronata) is dominant. Other plants usually as- 

 sociated in Eastern Scrub are: — Rhus dentata, Rhus 

 crosa, Asparagus stellatus, Asparagus medeoloides , Hete- 

 romorpha arhorescens, Phygelius capensis (near sti*eanis), 

 Royena hirsuta, Myrica aethiopica, Malvastrum sp,, Kig- 

 gelaria Dregeana, Rhamnus prinokles, Rul)us Lndwigii, 

 Ruhus rigidus, Printzia pyrifolia, Cussonia sp.. Clematis 

 hrachiata. 



In the undergrowth the following occur: — Richardia 

 africana^ Geranium Earveyi, Lobelia Preslii, Myosotis 

 afropalustris, Anthriscus sylvcstris, Ruhia petiolaris, 

 Thalictrum minus, Cephalaria sp., SchizoglQSsum hama- 

 turn, Scilla sp. (f ovatifolia) , and ferns. On the edges 

 of the formation on dry rocky soil Cliffortia linearifolia 

 often occurs. On fairly dry mountain sides the Eastern 

 Scrub formation gives place to the Leucosidea sericea 

 formation, especially at higher altitudes. On the damp 

 side of mountain kloofs sometimes Myrica sp. (No. 333) 

 is dominant. 



Formations at Higher Altitudes than the Cave 

 Sandstones. 



The rock consists of Drakensberg laya and basalt. 

 Leucosidea sericea occurs on mountain sides and 

 especially in kloofs. On damp shady slopes dense 

 thickets of Anindinaria tesselata occur. Fairly damp 

 high plateau and mountain sides are covered with tus- 

 socks of grass. In the tussock grass area Festuca scahra 

 is dominant. On dry or exposed or shallow gravelly soil 

 plants of ericoid habit are dominant. Thus on the moun- 

 tains there appear to be roughly four formations: — (1)
