This widely distributed species varies very much in appearance and pubescence, 

 the normal growth of prostrate leafy stems being totally different from the short 

 erect densely tufted stems, often with reduced leaves, which spring up after the 

 normal stems have been burnt off by the annual tires. Most, but not all, of the 

 normal specimens from Angola have broader and more ovate leaves than the eastern 

 specimens, whilst the secondary growths are indistinguishable ; the forms gradually 

 pass into one another. As specimens with pubescent and glabrous stems occur in the 

 same gathering, vars. benguelensis and rillosttla can sometimes only be distinguished 

 by the glabrous or hairy ovary. I am quite unable to distinguish specifically the 

 various forms here included under E. zambetiana from one another by any character 

 or chtiracters that have been assigned to them.
