DIAGNOSTIC DESCRIPTION
Shrub, 0.3-2 m tall, bushy, with stems erect, arching, often frondose. Stems red, 4-lined or 4-angled and strongly ancipitous when young, eventually 2-lined or terete; internodes 5-20 m long, shorter than leaves; bark reddish-brown. Leaves petiolate, with flat petiole 0-5-1 mm long; lamina 10-40 x 4-24 mm, all lanceolate or older ones ovate, acute to rounded-apiculate, margin plane, base narrowly to rarely broadly cuneate, ± densely glaucous beneath, chartaceous; venation: 3 pairs main laterals, with midrib branches and tertiary reticulum scarcely visible; laminar glands streaks (towards midrib) and dots; ventral glands usually ± dense. Inflorescence l-3(-10)-flowered, from 1-2 nodes, subcorymbiform, if from 2 nodes then with short apical internode, often with 1-3-flowered branches from middle of stem; pedicels 3-7 mm long; bracts narrowly oblong, deciduous. Flowers 15-30 mm in diam., ± deeply cyathiform; buds broadly ovoid to globose, obtuse to rounded. Sepals 3.5-6(9) x (1)2-5(6.5) mm, free, imbricate, subequal or unequal, erect in bud and fruit, oblong or elliptic to obovate-spathulate, rounded or very rarely obtuse, with margin entire, narrowly hyaline; midrib not or scarcely distinct, veins not or rarely slightly prominent; laminar glands linear, numerous. Petals golden to deep yellow, not tinged red, incurved, 9-18 x 5-12 mm, 2.5-3 x sepals, broadly obovate to subcircular, with apiculus lateral to subterminal, rounded to obscure; margin entire, without infra- marginal gland dots. Stamen fascicles each with 40-60 stamens, longest 4-6(8) mm long, 0.25-0.5 x petals; anthers golden to deep yellow. Ovary 3-5 x 2.5-3 mm, broadly ovoid to globose; styles 2.5-4.5 mm long, 0-6-0-9(1) x ovary, erect and ± divergent near apex or wholly outcurving; stigmas narrowly capitate. Capsule 7-11(13) x 7-11 mm, subglobose (or more rarely broadly ovoid) to globose. Seeds dark brown, 0.4-0.6 mm long, cylindric-ellipsoid, scarcely carinate, shallowly linear- foveolate.
