Ammocharis (Ammocharis)
Description
Ammocharis is a small genus from sub-Saharan Africa, in the Amaryllidaceae family (subfamily Amaryllidoideae) which includes 7 species distributed in Africa. The plant grows as a succulent, above-ground bulb, preferring seasonally wet, hot, sandy soils and full sun. Herbert segregated Ammocharis from Crinum in 1821, with two species, A. coranica and A. falcata (both originally Amaryllis). He also placed one of Linnaeus' original Amaryllis species, A. longifolia, in Crinum as C. capense. This species would also eventually find its way into Ammocharis. In 1847 Roemer placed Amaryllis longifolia in Ammocharis as Ammocharis longifolfolia, (Linn.) Roem. without realising it was conspecific with Ammocharis falcata. However many subsequent authors included only the two original species. A major review of the genus was undertaken by Milne-Redhead and Schweickerdt in 1939. In their recircumscription they identified five species. With respect to A. longifolia=falcata they concluded that while very closely related it was sufficiently distinct as to deserve of generic status, coining the term Cybistetes Greek: κυβιστητης, or tumbler, after the way the wind tumbles the infructescence. From then onwards Cybistetes was treated as a separate genus.
