subcapitate leafy inflorescence, sometimes solitary ones in the 
lower axils, their pedicels not jointed, 2 to 3 mm long. Calyx 
6 to 7 mm long, terete, not ribbed or angled, rather densely 
cinereous-pubescent and with long, white, ciliate hairs inter- 
mixed, the lobes 5, oblong-ovate, acute, 4 to 5 mm long. Corolla- 
lobes 5 to 6 mm long, oblong-obovate, obtuse, the tube very 
short. Stamens about 18, the tube about 1.5 mm long. Ovary 
depressed about 8-celled; styles 8, about 3 mm long; stigmas 
capitate. Mature carpels 5 to 8, prominently muricate, 3 to 4 
mm long, the projections with a minute tuft of hairs at the tips, 
the inner faces very prominently reticulate, the apex biaristate, 
the awns 1 mm long or less.

The relationship of this strongly marked species is apparently with 
the Australian Sida suhspicata F. Muell., but it is not closely allied to that 
species. It is well characterized by its tufted, simple stems, its long 
petioled, oblong, 3-nerved, cordate, small leaves 'which are prominently 
toothed in the upper part; its long stipules; its crowded flowers which 
form a dense, subcapitate, leafy inflorescence; and its prominently muri- 
cate, short-awned carpels which are strongly reticulate on the inner faces.
