DIAGNOSTIC DESCRIPTION
Shrub 0-7-1-7 m tall, ± spreading, with branches erect to arching. Stems red, 4-angled and ancipitous in first year, then terete, stout; internodes 8-60 mm long, shorter than to exceeding leaves; bark grey-brown. Leaves petiolate, with petiole 0-5-1 mm long; lamina 20-66(-80) x 5-35 mm, ovate or ovate-oblong to lanceolate or lanceolate-oblong, rounded or rarely apiculate-obtuse, margin plane, base narrowly to ± broadly cuneate, paler or somewhat glaucous beneath, chartaceous; venation: 2-3 pairs of main laterals (the upper forming distinct undulating intramarginal vein), the midrib branched distally, with lax obscure tertiary reticulum; laminar glands dots and short streaks; ventral glands densest or present only near midrib. Inflorescence l-7(-c. 25)-flowered, subcorymbiform, from apical node; pedicels 4-11 mm long; bracts foliar to narrowly lanceolate, persistent. Flowers 30-55 mm in diam., stellate to subcyathiform, buds ovoid-pyramidal, subacute. Sepals 6-9(-13) x 3-7 mm, free, imbricate, subequal, erect to outcurved in bud and fruit, broadly to narrowly ovate-oblong or very rarely foliaceous, acute or subacuminate to obtuse, with margin narrowly hyaline, entire or minutely denticulate towards apex; midrib conspicuous, veins not prominent; laminar glands linear, 8-10. Petals golden yellow, not red-tinged, spreading to reflexed, 16-30 x 10-17 mm, 2.5-3 x sepals, obovate, with apiculus subterminal, obtuse; margin entire to irregularly eroded-denticulate, eglandular. Stamen fascicles each with c. 40 stamens, longest 14-20 mm long, 0.75-0.85 x petals; anthers golden-yellow. Ovary 5-9 x 3.5-6 mm, ± broadly ovoid; styles 5.5-11 mm long, somewhat longer than ovary, free, suberect to divergent, outcurved near apex; stigmas truncate. Capsule 12-17 x 10-14 mm, ovoid-conic to ovoid. Seeds dark orange-brown, 15-20 mm long, narrowly cylindric, narrowly carinate, shallowly linear- reticulate.
