Namophila is a monotypic genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae).[1] The sole species Namophila urotepala is found only in Namibia.[2]

Description[edit]

Namophila urotepala grows from an underground bulb, which has a dark brown papery tunic. The bulb produces only two somewhat succulent leaves which spread out on the ground on either side. The flowers are produced in a several-flowered raceme borne on a very short stem so that the inflorescence is at ground level. At the top of the inflorescence is a tuft of bracts. Individual flowers are more-or-less upright, bell-shaped with fused greenish-white tepals which end in a thin "tail". The stamens are also more-or-less upright, with their filaments joined to the mouth of the tubular part of the tepals. The fruiting capsule remains enclosed in the tepals. The black seeds are somewhat globular.[3]

N. urotepala is found only in the mountains of southern Namibia, in arid areas with winter rainfall.[3]

Systematics[edit]

The genus and species were named by Ute Müller-Doblies and Dietrich Müller-Doblies in 1997.[4] Placed in the tribe Hyacintheae (or subfamily Hyacinthoideae by those who use the family Hyacinthaceae), Namophila is most closely related to Lachenalia.[3]
