This is the plant mentioned by Welwitsch, Apont. p. 586, n. 34, 

 where it is described as remarkably ornamental and well worth culti-

 use in cases of fever and diarrhoea. (See Welwitsch, Apont. p. 548 

 under n. 84.) The specimens associated here under this name com-

 to be arranged nnder distinct subspecies. Welwitsch in a note remarks
