Calyx 5-partite. Corolla with a very short tube enclosing the 
base of the staminal-column, and a broad saucer-shaped limp .5-lobed 
to halfway down; lobes deltoid, acute, valvate at the base and 
overlapping to the left at the apex in bud. Corona of 5 erect 
lanceolate-attenuate lobes, arising. from the staminal-column, with 
a crumpled gibbosity at their base, which rests on truncate pro- 
jections from the top of the filament-part of the staminal-column. 
Stamens arising from the base of the corolla-tube, united into a 
column around the ovary and style. Anthers erect, terminated by 
a short inflexed membranous appendage. Pollen-masses pendulous, 
elongate-clavate, compressed, attached in pairs by their attenuated 
ends to the short ovoid pollen-carriers. Style pentagonal, truncate 
or slightly convex at the apex, not exceeding the anthers. Follicles 
often solitary, inflated or lanceolate, smooth. Seeds ovate, com- 
pressed, crowned with a tuft of hairs. 
Species 2, one endemic in Tropical Africa, the other extending into 
India, Ceylon, Tonkin and Java.
