Notes
As stated by Dr. Schlechter in Engl. Jahrb. xxi. Beibl. 54, 6, the name Gomphocarpus marginatus has been erroneously applied to this plant in many Herbaria. The flowers of the type and var. sordida look so very distinct in size and appearance that they might perhaps be regarded as different species, but they seem quite connected by the var. Calceolus, which sometimes (Gerrard, 1295, Fannin, 12) also has subquadrate corona-lobes.
