A low wiry herb, annual or perhaps persisting for several 

 years ; rootstock long, descending in a more or less twisted 

 manner, hard or somewhat woody, giving off at its crown several 

 prostrate or decumbent stems ; stems nearly simple below or more 

 or less branched, floccose-lanate or glabrescent below, rather 

 slender ; leaves alternate, sublinear or oblanceolate, obtuse or 

 somewhat pointed and often nigro-apiculate at the apex, not 

 very narrow at the sessile non-decurrent base, more or less hoary- 

 woolly on both faces or sub-obsoletely so, nearly flat or with 

 revolute margins, rigid, |- to 1 in. long, entire or slightly wavy on 

 the margins ; capitula rosy-red when young, yellowish at the 

 time of flowering, campanulate-oblong, y to J in. long, subsessUe 

 or sessile, usually with some loose wool at the base, about 

 20-flowered, homogamous, crowded many or several together in 

 sessile terminal hemispherical or subglobose clusters x *o t ™- ^^ 

 diameter ; involucral scales plnriseriate, imbricate, obovate or 

 oblanceolate, thinly hyaline and white (in the dry state) except 

 the unguiculate basal part, glabrous, rounded and occasionally 

 cleft at the white apex, suberect or those of the outer capitula 

 often with squarrose or revolute tips, usually somewhat rosy 

 about the middle, the innermost ones about equalling the corollas, 

 the outer ones successively rather shorter; florets all hermaphrodite; 

 corolla narrowly tubular, glabrous, yellow ; ovary scattered with 

 minute glands, otherwise glabrous ; pappus pale-straw-coloured 

 or whitish (in the dry state), setose, equalling the corolla, brittle,
