 spuriously 2-lobed, induplicate- valvate or imbricate. Stamens fertile 

 elongate ; filaments incurved ; anthers introrse, sometimes apiculate. 

 Styles (in female flowers) elongate, incurved ; stylopods subplane or 

 thickly squamiform within and concave above. Fruit subovate or 

 obovate, compressed contrary to septum, at base highly emarginate or 

 cordate ; carpophore simple. Primary ridges subequal thin, curved 

 or branched ; secondary sometimes oo , unequal. Seed laterally 

 compressed. — Small shrubs or herbs, erect or decumbent, glabrous or 

 with simple and stellate hairs ; leaves entire, dentate, lobed or 3-nato- 

 dissected ; umbels compound or subcapitate ; bracts of involucre small

 sepals dentiform or 0. Petals subequal or unequal, entire or retuse ; 

 point sometimes shortly inflexed ; valvate or imbricate in prsefloration. 

 Styles slender; stylopods depressed disklike. Fruit compressed 

 contrary to septum ; primary ridges thin often curved ; dorsal some- 

 times rather prominent marginate. Other characters of Trachymene, 

 — Perennial herbs or virgate shrubs ; leaves entire, few or squamiform ; 

 the lower sometimes dissected; umbels simple or at top of twigs 

 compound ; involucral bracts few or 0. [Australia^)
