FLORA OF TASMANIA. [Composite 
about -| inch long, broadly sheathing at the base, the rest subulate, acuminate, very thick and coriaceous, the mar- 
gins obscurely cartilaginous and serrulate, bright green. Capilulum very small, when in flower hidden amongst the 
uppermost leaves, on a short, terminal peduncle, which elongates after flowering. Involucral scales erect, about four 
or five, forming together a subcampanulate cup, much shorter than the florets, or even than the achenia. Flowers 
about four, the three outer female, the inner larger, and male. Perianth of male flowers clavate, four-toothed, the 
teeth large, erect ; of the female shorter, narrower, tubular, and also cleft, the teeth spreading. Stamens nearly 
free, half-exscrted. Styles all exserted ; of the male capitula two-lobed, of the female bifid. Achenia all larger 
than the involucral scales, short obovate, tetragonous, with the angles keeled, truncated at the broad apex, its coat 
coriaceous. Seed broadly ovoid. (Name from o-kX^os, hard, and Aei/wa, a scale; in allusion to the coriaceous 
involucral scales.)

Boot perennial. Stems few, erect, very slender, 1-2 feet high, sparingly branched, white with oppressed down, 
as are the leaves. Leaves in scattered pairs, opposite, linear, sharp or blunt, quite entire, 1 inch long. Inflorescence 
a spherical or oblong white head, composed of innumerable minute, sessile, few-flowered capitula. Capitula three- 
flowered, with no bracts or leaves surrounding or subtending them. Involucral scales few, scarious, blunt. Flowers 
hermaphrodite, all similar. Corolla tubular, five-toothed. Achenia obovoid, with a scanty pappus of slender hairs, 
which are plumose towards the apex. (Name from koAos, beautiful, and kc^oAt/, a head- in allusion to the pretty 
snow-white glomeruli of the inflorescence.)

This is a very variable plant in Tasmania, where however none of the specimens that I have seen equal in size those 
from South-western Australia, which hence seem to form a distinct variety. As a genua it appears too closely allied 
to ]j<»rop}njta, but differs materially in the alternate leaves, and in the glomeruli of the capitula being subtended by
