Australian Plants. 



simple, ovate or subcordate, blunt, sessile, with revolute 

 margin; flowers tetrandrous, axillary, solitary, on short 

 pedicels, forming at the end of the branches a fohate raceme; 

 sepals acute lanceolate, half as long as the corolla ; filaments 

 hispidulous ; carpels elliptico-oblong, compressed, pubescent. 



On sandyplaces about Encounter Bayand in Kangaroo Island. 



By this interesting species the genus Zieria becomes 

 united with Boronia, to which I am also inclined to refer 

 Cyanothamnus. 



17. Boronia clavellifolia, 



Fruticose, difi^use, much branched, smooth ; branches tuber- 

 eulate ; leaflets small, ternate, ^ short-stalked, sub-clavate, 

 terete, blunt; flowers axillary and terminal, solitary, ge- 

 minate or ternate, octandrous ; pedicels shorter than the flower ; 

 sepals ovate-triangular, ciliolate, less than half as long as the 

 corolla ; fllaments smooth, glandulose. 



On sandy, loamy plains in the scrub near Lake Lalbert 

 and towards the mouth of the Murray River. 



MALVACEAE. 



18. Sida intricata, 



Fruticulose, upright or diffuse, much branched; leaves 

 small, ovat-roundish, truncate at the top, toothed, but entire 

 at the cuneate base, above scantily, beneath densely covered 

 with grey stellate hair, petioles much shorter than the leaves, 

 surpassing in length often the subulate-setaceous stipules, 

 peduncles axillary, solitary, drooping, shorter than the 

 leaves ; segments of the calyx subdeltoid ; carpels flve, a little 

 depressed, on the back almost even and puberulous, at 

 the commissura netted ; seeds brown, puberulous. 



In sandy, loamy plains between Mount Hope and the 

 Murray, also towards the Darling River. 



It bears some affinity to Sida corrugata, but its growth is 

 upright intricate, it is much more robust, the flowers and 

 leaves and capsules are much smaller, the latter not rough. 



19. Sida humillima, 



Suffruticose, procumbent; leaves thin, ovate-oblong, obtuse, 

 cordate or rounded at the base, unequally and deeply crenate, 

 above scantily, beneath densely covered with a stellate some- 

 what shining indument ; petioles hardly of the length of the 

 leaves, but longer than the subidate-linear stipules ; peduncles 

 axillary, solitary or two or three together, filiform, towards 

 the middle articulated, sub-equal to the length of the petiole ;
