Capitula discoid, homogamous, terminal, few-to many-headed (3-40), simple to compound corymbs, pedunculate; peduncles 2.0-33.0 mm long, white to silvery tomentose. Involucre 5.0-8.0 x 3.0-5.0 mm, narrowly campanulate to urceolate, apically constricted, sometimes tapering at the base; involucral bracts 4-or 5-seriate, tightly arranged, margins and apices scarious, membranous apices of all bracts 0.3-0.8 mm long, glabrous to slightly or densely pubescent or villous, especially edges, very rigid, brown margins light and inconspicuous, median resin canals present; outer bracts deltoid to lanceolate, 2.2-3.3 mm long, acute to acuminate; middle bracts deltoid to ovate, 2.7-3.4 mm long, acuminate; inner bracts deltoid to lanceolate, 2.7-4.0 mm long, acuminate to rounded; second inner bracts ovate, 3.0-5.0 mm long, rounded; innermost bracts ovate, 4.3-5.8 mm long, rounded. Receptacle convex to flat; paleae in two marginal series, linear to oblong, 4.3-6.0 mm long, rounded, rigid with scarious margins and apices, scarious apices 0.8-1.1 mm long. Disc florets 37-55, without resin canals; corolla 2.3-3.2 mm long, with only glandular trichomes, yellow; tube 1.4-1.8 mm long; limb narrowly campanulate, 1.0-1.4 mm long (excluding lobes); lobes spreading, 0.6-1.0 mm long, narrowly triangular. Anthers 2.7-3.8 mm long (including apical appendage); apical appendage oblong. Style 2.0-3.3 mm long (excluding branches); branches 0.5 mm long. Cypselas 1.8-2.0 x 0.5 mm, oblong to obovate, 11-ribbed, apical rim thickened, entire to slightly dentate, glandular trichomes present, sparse, scattered, not mucilaginous when soaked, discontinuous resin canals in ribs absent. Flowering is in late summer to autumn from February to May.
