Aneilema

Aneilema is a genus of monocotyledonous plants of approximately 60 species. The vast majority of the species are native to sub-Saharan Africa, but a few are found in Oceania and one, Aneilema brasiliense, is from South America. It is the third largest genus in the family Commelinaceae after Commelina and Tradescantia, and it is one of only six genera in the family to occur in both the Eastern Hemisphere and the Western Hemisphere. Aneilema consists of herbs that may be either perennial or annual. They are characterised by their zygomorphic flowers which, unlike the closely related genus Commelina, usually lack a modified leaf enclosing the flower stalk at maturity. The uppermost leaf on the flowering stalk is often highly modified, however, and in a few species, such as Aneilema clarkei, the upper leaf does completely surround the inflorescence. The flowering stalks of Aneilema tend to be much larger than those of Commelina, with some species having inflorescences of more than 25 cm i......read more on Wikipedia.
