Specimens (Giljlllan in Ilcrh. Galpln, G070), collected on a ridge at Zwart 

 Krans Cave^, Krugersdorp, in the Transvaal, have the smaller habit and general

 those of E. rectinuna, Posisibly it may prove to be distinct^ but requires to be 

 compared with living plants of both species. 



This is either a very variable plant or more than one species is here included 

 under this name, but from the material seen I have been unable to obtain
