(Ancistrostigma, Fenzl.) 
Calyx free, more or less deeply 5-lobed. Petals none. Stamens inserted 
at the top of the calyx-tube, either 5 alternating with its lobes or indefinite. 
Ovary free or nearly so, enclosed in the calyx, either 2-celled with 2 styles, or 
l-celled (reduced to 1 carpel) with 1 excentrical or lateral style; ovules 2 or 
more in each cell, attached to a basal placenta, free or shortly adnate to the 
partition. Capsule membranous or hard, transversely circumsciss, and when 
2-celled the upper portion sometimes separating septicidally into 2 cocci, and 
in some species, not Australian, divided inside by a transverse partition under 
‘the uppermost seed. Seeds orbicular or reniform, the testa often granular.— 
Prostrate or diffuse herbs, rarely woody at the base. Leaves opposite, the 
two of each pair unequal in size, the petioles often with a scarious dilatation 
at the base, but no real stipules. Flowers axillary, solitary or in cymes or 
clusters. Bracts and bracteoles often somewhat scarious 
The genus is dispersed over the tropical and subtropical regions of the New as well as the 
Old World. Of the 6 Australian species, 2 are widely distributed over the warmer regions 
of Asia and Africa, the 4 others are endemic
