Description:
Erect shrub 70 cm-l.5 m tall; branches thinly tomentose, with emergent yellow glandular hairs, the vestiture interrupted by narrow glandular-scabrous ridges of tissue arising from the recurved margins of the decurrent leaves; leaves linear to narrowly oblanceolate, with a broad usually retuse sometimes rounded, hooked apex resulting from the recurving of the apiculate tip, and with a broadly decurrent base slightly constricted at the point of attachment, 8-25 mm long, 1-3 mm wide, discolorous, green and glandular-scabrous on the upper side, on the underside with a vestiture similar to that on the branches and often yellowish with exudate.
Capitula very numerous in rounded more or less dense terminal corymbs, on short peduncles (2-3 mm), narrowly turbinate, 3-4 mm long, 2.5-3 mm diam.; involucral bracts 6-8-seriate, the inner ones longest, all with never patent, convex glabrous white to creamy-while (or in the outermost stramineous) opaque orbicular laminae; florets 10-12, all bisexual, or 1-3 outer ones female.
Achenes oblong, subcircular to more or less 4-angled in cross-section, mid-brown, sparsely pubescent, with antrorsely appressed colourless papillae; pappus bristles minutely barbellate, slightly more coarsely so towards the apex, about as long as the corolla, of bisexual florets 15-20, of female florets none.
