DIAGNOSTIC DESCRIPTION
Shrub or small tree (0.2-)1-7(-10) m tall, slender, much branched, with branches drooping then ascending. Stems yellow-brown when young, soon 2-angled, eventually terete; internodes 2-20(-35) mm long, usually much shorter than leaves; bark red-brown to grey. Leaves sessile; lamina 17-50 x 3-10 mm, narrowly lanceolate to ± narrowly elliptic or more rarely elliptic or oblanceolate, acute to rounded, margin plane to ± recurved, base narrowly to broadly cuneate, reflexed-auriculate, paler beneath or concolorous, sometimes ± glaucous, subcoriaceous, lower ones eventually deciduous; venation: (1)3-5 basal or near-basal veins, the laterals branching dichotomously near the base, with numerous parallel or interrupted and ± vestigial secondary veins, without or with 1-10 cross-veins and a loose or ± dense tertiary reticulum; laminar glands in secondary venous system either (i) not interrupted and alternating with ± irregular series of short streaks and lines or (ii) interrupted and wholly streaks or dots; marginal glands pale to dark, dense. Inflorescence 1-flowered; pedicel 5-15 mm long; bracts foliar but smaller. Flowers (35-)40-70 mm in diam., cyathiform to stellate; buds ovoid, acute. Sepals 7-11 x 4-7 mm, imbricate, subequal, erect in bud, ovate to triangular-ovate, acute to rounded, margin entire or ± minutely glandular-ciliolate (especially towards the apex), midrib undifferentiated or obscure; laminar glands linear, numerous; submarginal glands absent or dark; marginal glands absent or dark. Petals golden yellow, not flushed red or orange outside, persistent, spreading, 25-38 x 15-25 mm, c. 3-5 x sepals, broadly to narrowly obovate, with apiculus small, rounded; margin entire or with minute dark sessile glands or glandular cilia, rarely with a few dark intramarginal dots distal to apiculus; laminar glands linear, scarcely interrupted distally. Stamen fascicles persistent, each with 20-25 stamens, longest 15-22(-28) mm long, c. 0-6-0-8 x petals, with filaments united for c. 1 mm. Ovary 5-10 x 3-5-7 mm, ovoid-conic; styles 8-18 mm long, 1-2-3 x ovary, 0-6-0-9 coherent, ascending distally; stigmas subglobose to narrowly capitate. Capsule 12-14 x 10-12 mm, ovoid-pyramidal.Seeds reddish-brown, 1.0-1.6 mm long, narrowly cylindric to fusiform, not carinate or winged or with distal expansion, finely linear-reticulate,
