AUSTRALIAN PLANTS. 147 



glaiid-bcaring hair; rluzomc divided, somewhat woody ; stems nume- 

 rous, procumbent or adscendent, leafless at the summit; leaves obovate 



■ 



or oblong-euneate, the uppermost sessile, the rest tapering into a pe- 

 tiole, beyond the middle toothed or laciniate ; scales of the involucre 

 ovate -lanceolate, glaiidulous-pubesceut ; achenes ovate -cuneate, very 

 strongly compressed, deep brown, glabrous, asperous, with a thin mar- 

 gin ; awns four to seven, setaceous, unequal in length at the apex, 

 retro-aculeate, scabrid at the base, alternating with an equal number of 

 oblong or obovate-cuneate scales, which are ciliate at the top. 



Hab. On dry grassy ridges near the Snowy River and its tributaries, 

 towards Maneroo. The colour of the ray is blue, as in 0. cuneifolia^ 

 ladocarpa^ and dentex. This character is not without importance for 

 distinguishing the various species. Thus Cdilatata^ antJiemoideSyScapi- 

 gera, and scabiosifolia have whitish radial flowers ; C. microphylla^ Muel- 

 lerii^ midtisela^ erinacea, and lappulacea^ yellow ones. Those of C. 

 {Cheiroloma) Jiispidula^ cymbacantJia, and hretheta^ are yet to be observed. 



The genus Cheiroloma may be referred as a fifth section to this genus. 



102. Calotis (Sect. Acantharia) aw/7^mo/&5, E. Muell.; smooth; root 

 fibrous, producing runners ; stems simple ; radical leaves on long peti- 

 oles, pinnately divided, the lower segments linear, entire, the rest pin- 

 nately cut into linear-acute divisions ; leaves of the stem small, remote, 

 sessile, lanceolate, entire or rarely toothed ; scales of the involucre few, 

 disposed in tvvo rows, ciliate, but smooth on the back, outer ones almost 

 round ; achenia cuneate, a little compressed, margined and broadly 

 winged, with exception of the tops, evcp and smooth; awns generally 

 eight, valid, retro-hispid, alternately very short, and of the length of 



the achenium. 



Hab. Iu muddy localities in the neiglibourbood of St;ition Peak. 



A singular plant, differing from the rest of the species, as well in 

 habit as in the hermaphrodite flowers of the disc. Eay whitish. 



103. Brachycome hplocarpa, F. Muell. ; annual ; leaves linear- 

 cuneate, as well as the branches covered with articulate hair, at the 

 upper end cut or pinuatifid, their teeth or segments acute ; peduncles 

 naked, filiform, upwards smootli ; scales of the involucre blunt, gla- 

 brous ; achenia cuneate -linear, compressed, pale brown, with naked 

 margin, on both si<Ies hairy-scabrous ; pappus conspicuous. 



Hab. In low grass-land, not unfrcqueut in the colony of Victoria, 

 as wt'll as in South Australia. Similar to B. deb'd'a.
