Perennial herb, up to 1 m high; branching from base, woody, glabrous or sparsely hairy, leafy, often with axillary leaf tufts. Leaves: blade linear to very narrowly elliptic, up to 100 x 10 mm, apex acute, base half-clasping, often hastately eared, lower leaves sometimes narrowed to petiole-like base, margins ± revolute, denticulate, sometimes coarsely dentate or pinnately lobed; glabrous, stems uniformly leafy. Heads radiate, few to many on long, bracteate peduncles arranged in open, corymbose panicles. Involucral bracts 20, (4-)5(-7) mm long, slightly shorter than or equalling disc florets; calyculus bracts few, often dark tipped, not overlapping, much shorter than involucre. Flowers: ray florets 7-13; ray and disc florets canary-yellow; Jul.-Jun. Fruit with cypsela (and ovary?) cylindric, hispid between ribs. (including S. laevigatus Thunb. var. integrifolius Harv.) Often misidentified as S. burchellii DC., but that species only occurs in WC.
