Leaves: largest 10–18 × 2–3 mm; capitular leaves subtending glomerules only, or sometimes also hidden between and surpassed by heads. Heads proximal and distal, in spiciform or racemiform arrays, ± spheric, 1.5–2 mm, heights ± equal to diams. Receptacles ± spheric, 0.3–0.5 mm, heights ± equal to diams. Pistillate paleae scarcely imbricate, longest 0.9–1.3 mm. Bisexual paleae mostly 1–3, apices incurved, ± involute, gibbous. Functionally staminate florets usually 0. Bisexual florets 3–5; corollas protruding from heads, ± zygomorphic, 0.5–0.9 mm, glabrous, lobes unequal (1–2 enlarged). Cypselae rounded, ± terete, mostly 0.5–0.6 mm (bisexual slightly longer). 2n = 14.
