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 subspicata 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.

A tree about 6 m high, all parts prominently setose, the setae 

 pale-brownish, rather soft, spreading, thickened below, slenderly 

 acuminate and minutely puberulent. Branches brown, terete, the

 8 cm wide, the upper surface dark-olivaceous, the lower pale, 

 apex acute to acuminate, base obtuse, margins irregularly spin-
