Described from living stems and flowers preserved in fluid. Dr. Schlechter 
described and figured this species from a plant cultivated in the Botanic Garden 
at Berlin, which he states was probably introduced by Dr. Stuhlmann from East 
Tropical Africa, but this locality is almost certainly an error.
