Description: Perennial herbs with variably woolly branches, produced into slender sparsely bracteate peduncles.
Leaves linear to oblong.
Involucre hemispherical to turbinate; bracts linear or linear-acuminate, scarious, herbaceous or cartilaginous, with a narrow scarious margin; stereome fenestrate; lamina pale brown, scarious, not radiating. Receptacle naked, convex or conical. Florets bisexual or the outer female; corolla tube slender below, narrow turbinate to campanulate above, shortly exceeding the bracts, usually yellow; lobes 5 (3 or 4 in female), smooth within. Anther tails long and firm. Style apex truncate to rounded.
Achene terete or somewhat compressed, 2–4 ribbed, not beaked; pericarp cartilaginous, striate, with scattered paired linear transparent cells among linear translucent cells, smooth ot sparsely glandular and with a few minute unicellular hairs. Pappus bristles linear to filiform, barbellate, persistent.
Distribution and occurrence: Endemic genus of ten species.
