A shrub. Branchlets about 7 mm diameter, hidden by leaf bases. Leaves crowded, somewhat rigid, 1-1.2 cm broad, with the leaves below the inflorescence slightly larger, lanceolate, subobtuse, partly decurrent on the branchlets with the midrib distinct beneath, slightly keeled beneath on the upper portion, densely glandular on both surfaces, glandular-ciliate on the margins. Heads several, crowded within a common sessile bracteate inflorescence which is 4-4.5 cm in diameter and surrounded by the upper leaves. Rays of common involucre female; tube 4 mm long, cylindric, glandular; limb 1.2 cm long, 3.5 mm broad, oblong, irregularly 3-lobed at the apex (more rarely 2-lobed or entire), with one or more of the sinuses produced into a short spur-like body at the back of the limb. Style-branches not infrequently 3, usually 2, linear, exserted from the tube. Involucral-bracts of individual heads free, 8 mm long, 0.75 mm broad, linear, somewhat lacerated on the upper margins, sparsely glandular. Ray-florets of individual heads female. Corolla-tube 4.5 mm long, cylindric, glandular-hairy; limb 2.5 mm long, 1 mm broad, linear-oblong, entire. Ovary 3 mm long, linear in outline; style-lobes almost reaching the top of the limb. Pappus of free unequal scales 1.3 mm long. Disc-floret bisexual. Corolla-tube cylindric, 4 mm long and 0.5 mm diameter below, glandular, then becoming campanulate and 2 mm long and 1.25 mm diameter in the campanulate portion. Anthers obtuse at the base. Ovary 4 mm long, cylindric, glabrous; style-lobes obtuse. Pappus of irregular free paleae 1-5 mm long.
