Some hitherto unknown Australian Plants. 43 



Calycothrix brachychaeta. 



Leaves linear-triangular, crowded, glabrous or pubescent, 

 almost blunt, stalked ; flowers sessile, collected in leafy 

 spikes ; bracteoles free, dilated at tbe truncate and 

 ciliate apex, as long as tbe silky- downy tube of the 

 calyx, or but little shorter, pointed by the apex of the 

 keel ; lobes of the calyx lanceolate, outside downy, gra- 

 dually terminating in a ciliate acumen, but scarcely in a 

 distinct bristle; petals white, lanceolate, acuminate, 

 almost as long as the calyx-lobes ; stamens 15-20. 

 On stony ridges along the rivers Victoria, Fitzmaurice and 

 Roper. 



A tall shrub. Leaves 2-3 lines long. Tube of the calyx 

 1^-2 lines long, slightly contracted towards the summit, 

 hardly longer than the lobes. 



This species bears, amongst its numerous congeners, only 

 comparison with C. conferta and the following one. 



Calycothrix achaeta. 



(Sect. Lhotzkya.) 



TLhotzkya cuspidata, Ferd. Meuller, in Hooker's Journal of Botany, 1856, 

 page 324.] 



Hirtellous ; branchlets very short, crowded ; leaves on 

 short stalks, very minute, densely imbricate, oblong- 

 triangular, almost blunt, above one nerved, beneath 

 scarcely keeled ; stipules, none ; flowers sessile ; brac- 

 teoles free, obcordate, fringed, keeled, apiculate, £ 

 shorter than the calyx-tube ; lobes of the calyx ciliate, 

 ovate or cordate orbicular, cuspidate by a short acumen, 

 not much shorter than the ovate silky-downy tube, with- 

 out manifest bristle ; petals white, narrow, oblong-lan- 

 ceolate, of twice the length of the calyx-limb ; stamens 

 12-17 ; gland of the anthers conspicuous, double. 

 On the sandstone table land of Arnhem's Land. 

 A shrub 5-8 ' high. Leaves never much longer, often 

 shorter, than one line. Tube of the calyx about one line 

 long. Anthers round, yellowish. Style of equal length with 

 the longer filaments. 



Referring to Chamselauciese, I may mention, on this 

 occasion, that the Homaloxalyx ericaeus is to be combined 

 with Tryptomene, as Tr. homalocalyx.
