Var. radiolatus, Kirk, Students' Fl. 341.—More or less pubescent. Lower leaves broad, membranous, narrowed into slender petioles, toothed or lobed or pinnatifid; upper sessile, auricled at the base. Heads ⅓–½ in., radiate; rays short, broad. Achenes very mucilaginous when soaked in warm water.—S. radiolatus, ''F. Muell. Veg. Chath. Is. 24, t. 4. Chatham Islands, H. H. Travers!

Leaves 2–4 in. long, ½–1 in. wide, oblanceolate or oblong-obovate or obovate-spathulate, obtuse or subacute, gradually narrowed into broad flat petioles, not dilated nor sheathing at the base, irregularly sinuate-dentate or serrate, rather thin, very glaucous; margins somewhat thickened. Upper leaves narrower, lanceolate or linear-lanceolate, serrate, gradually passing into narrow-linear entire bracts.
