The South African Species of Lagarosiphon

Examining dried m aterial, especially of such small dimensions, is not very satis factory. Living plants must be studied in the m anner in which it was done by W ager, to give us a more complete picture o f their life-history. As so little was known about these species when W right made his com pilation for the Flora of Tropical Africa, his treatm ent of them is unsatisfactory. Some are no better than generic descriptions and without having seen the types, it is impossible to recognize the plants concerned.
