Shrub 0-6-2 m tall, with branches erect to ascending. Stems orange, 4-angled and ancipitous in first year (or longer), then terete; internodes 10-50 mm long, shorter than to exceeding leaves; bark grey-brown. Leaves broadly petiolate, with petiole 0.5-1(1.5) mm, long; lamina 18-42(-60) x 6-15(-20) mm, oblong or elliptic-oblong to narrowly elliptic (sometimes lanceolate towards apex ef shoot and oblanceolate towards base), obtuse (rarely subacute) or apiculate to rounded, margin plane, ± recurved, base cuneate, markedly paler to glaucous beneath, chartaceous to subcoriaceous; venation: 1-2 pairs main laterals (the upper forming distinct, often ± straight intramarginal vein), with midrib rather obscurely branched distally, with rather dense but very obscure or invisible tertiary reticulum; laminar glands ± small dots and sometimes short streaks, ventral glands sparse to rather dense. Inflorescence l-3(-6)-flowered, from apical node, subcorymbiform; pedicels 7-17 mm long; bracts foliar to lanceolate, persistent. Flowers 30-50 mm in diam., stellate; buds ovoid, acute to subapiculate. Sepals (5-)6-9(-11) x 3-4(-6) mm, free, imbricate, subequal, ± outcurved in bud and fruit, ovate to narrowly lanceolate, acute or acuminate, with margin subentire or minutely and ± irregularly denticulate (especially towards apex); midrib ± conspicuous, veins not prominent; laminar glands linear or interrupted, c. 8. Petals deep yellow, sometimes tinged red, spreading or reflexed, 16-25 x 10-15 mm, 2.5-3 x sepals, obovate, with apiculus lateral, subacute to obtuse, margin entire or often minutely glandular-denticulate especially around apiculus. Stamen fascicles each with 40-65 stamens, longest (10)15-18 mm, long, 0.75-0.85 x petals; anthers yellow to orange-yellow. Ovary 5-7 x 3.5-4.5 mm, ± narrowly ovoid-conic; styles (3-)4-6(-8) mm, long, equalling to slightly longer than ovary, free, suberect, outcurved near apex; stigmas truncate to narrowly subcapitate. Capsule 9-15 x 8-10 mm, ovoid to narrowly ovoid-conic, turning bright red during maturation. Seeds dark orange-brown to reddish-brown, 1-1.1 mm long, narrowly cylindric, narrowly carinate with terminal expansion, shallowly linear-foveolate.
