Notes
L. sansibarensis exhibits considerable variation in the shape of the leaves, and some of its forms have been considered distinct species. L. Volkensii, Engl., differs from typical sansibarensis in having thicker leaves. It is probably only a form of L. sansibarensis, but this cannot be decided until fully developed flowers are known. The type specimens bear only very young flower-buds. L. crassissimus, Engl. in Engl. Jahrb. xx. 122, is a mixture of L. Kayseri and L. sansibarensis .
