Very nearly allied to E. atrovirens and not distinguishable by floral characters, 
in either sex, from that well-marked species. As a rule, however, the two are 
quite unlike each other as regards shape of leaf, while they possess a different 
indumentum. So distinctive a facies is thus imparted to the two plants that hitherto 
no confusion has taken place between them. On the other hand, the general facies 
of E. oleracea is so like that of E. Welivitschiana that it bears as close a resem¬ 
blance to E. africana as E. Welwitschiana does. Male specimens of these three 
species, on this account, call for care in their discrimination, and the writer has 
experienced exactly the difficulty which others have met with. Fortunately, how¬ 
ever, the female flowers of these three plants are widely different, the stigmas of 
E. africana being subsessile and papillose, those of the other two smooth and at the 
apex of a distinct style. But these two are readily distinguishable because the stigmas 
of E. Welwitschiana are very small and suberect, much shorter than the style, while 
those of E. oleracea are at first divaricate and ultimately recurved and longer than the 
style. It is to be remarked that in the extreme west (N. Cameroons) of the wide area 
which the two allies occupy and again in the extreme east (Uganda proper) of this 
area, E. atrovirens and E. oleracea occur together. In the intervening region, 
however, E. atrovirens has so far only been found to the north of the Congo, while
