Inflorescences axillary and terminal, mostly open, 5–15+-flowered cymes. Pedicels shorter to longer than subtending bracts at maturity. Flowers: sepals with weak veins arcing outward at midsection and ± confluent apically, lanceolate to ovate (herbaceous portion similar), 2–4(–5) mm, ± equal, apex acute to acuminate (herbaceous portion similar), not hooded, glabrous or with ± sessile glands; petals 2-fid for 3/4+ their total length, 2–3 mm, 1/2–2/3 times as long as sepals, lobes 1-veined, vein unbranched, linear, trunk absent, base abruptly tapered, apex rounded to acute.
