Flowers monecious, apetalous. Male: Calyx globose, splitting 
into 2-3 valvate segments. Stamens numerous, free, inserted on a 
hemispherical receptacle, mixed with oblong pilose glands ; anthers small,

The characters of this species are, with the single exception of the presence of a 
rudimentary ovary in the male flower, those of Argomuellera macrophylla, Pax. 
The rudimentary ovary has a solitary distinct chamber with a well-developed
