DIAGNOSTIC DESCRIPTION
Shrub 0.3-1.5 m tall, often forming low thickets, with branches dense, erect or arching. Stem red to orange, 4-angled and slightly ancipitous at first, very soon terete; internodes 10-80 mm long, usually equalling or exceeding leaves; bark grey-brown. Leaves petiolate, with petiole 0.5-2.5 mm long; lamina 15-65(-78) x 7-43 mm, broadly ovate to broadly rhombic-ovate or subcircular, obtuse to rounded or emarginate, often apiculate, margin usually undulate, base truncate or subcordate, paler or glaucous beneath, chartaceous; venation: 3-4 pairs main laterals (the upper not distinctly intramarginal), with midrib obscurely branched distally with or apparently without ± clear lax tertiary reticulum; laminar glands dots and short streaks, ventral glands absent or ± dense. Inflorescence 1-7-flowered, from apical node, subcorymbiform, rarely with flowering branches from lower nodes; pedicels 3-14 mm long (-30 mm in fruit); bracts foliar to narrowly elliptic, persistent to deciduous. Flowers15-25(-39)mm in diam., cyathiform; buds broadly ovoid, obtuse to rounded. Sepals 3-9 x 2.5-6 mm, free, imbricate, subequal, erect in bud and fruit, narrowlyly elliptic to obovate, rounded to subapiculate, with margin entire or finely eroded-denticulate towards apex and often scarious; midrib rarely conspicuous, veins not prominent; laminar glands linear, c. 12. Petals golden yellow to butter-yellow or rarely pale yellow, not red-tinged, incurved, 15-25(-30) x 11-21(-25) mm, 3-5 x sepals, broadly to narrowly obovate, with apiculus subterminal, rounded, margin entire. Stamen fascicles each with 25-65 stamens, longest 6-11 mm long, 0.35-0.4x petals; anthers deep golden yellow. Ovary 4-6 x 3-3.5 mm, narrowly to broadly ovoid; styles 3-5 mm long, 0-6-1 x ovary, free, suberect to divergent, outcurved near apex; stigmas small. Capsule 10-15 x 6-10 mm, narrowly to broadly ovoid, often puckered. Seeds dark reddish-brown, 0.8-1 mm long, narrowly cylindric, ± carinate, shallowly scalariform-reticulate.
