DIAGNOSTIC DESCRIPTION
Shrub or tree 0.5-6 m tall, loosely branched, with branches spreading or ascending. Stems red when young, soon terete; internodes 10-26 mm long, shorter than leaves; bark grey. Leaves sessile or very shortly petiolate (to 1 mm); lamina (16-)20-90 x 5-27 mm, ovate-lanceolate to oblong-elliptic or oblanceolate, acute to subacute or subapiculate-obtuse, margin plane to recurved, base cuneate to cordate-amplexicaul, sometimes subauriculate, paler beneath, not or scarcely glaucous, chartaceous, lower ones eventually deciduous; venation: 5-7(9) basal and lower lateral veins (i.e. midrib + 2-4 pairs), the laterals unbranched, the midrib pinnately branched distally, usually linked by cross-veins, with numerous secondary veins continuous or ± interrupted by ± dense tertiary reticulum; laminar glands in secondary venous system, lines alternating with ± irregular series of small dots and short streaks; marginal glands dark, dense. Inflorescence (l)3-9-flowered, from 1(2) nodes, often with lateral flowering branches; pedicels 10-25 mm long; bracts intermediate. Flowers 35-70 mm in diam., stellate; buds ovoid, acute. Sepals 5-15 x 2-5 mm, imbricate to basally open, unequal, reflexed in fruit, ovate-lanceolate totriangular-lanceolate, acute, margin glandular-ciliate or -denticulate, midrib undifferentiated; laminar glands linear, numerous; submarginal and marginal glands dark. Petals golden yellow to lemon-yellow, not tinged, tardily deciduous, spreadingto reflexed, (17-)20-41 x 10-25 mm, 2-3 x sepals, obovate, with apiculus obtuse; external margin with few sessile or intramarginal dark reddish glands, internal margin dark-glandular-ciliate; laminar glands linear, not interrupted. Stamen fascicles tardily deciduous, each with c. 30 stamens, longest 15-22(25) mm long, 0.5-0.75 x petals, with filaments very shortly united. Ovary 5-8 x 3-5 mm, rather broadly to narrowly ovoid; styles 8-13 mm long, 1.2-1.6 x ovary, completely or almost completely coherent; stigma mass capitate or subcapitate. Capsule 10-16 x 5-10 mm, broadly to narrowly ovoid. Seeds yellow-brown, c. 1 mm long, cylindric, not winged, slightly carinate, shallowly linear-reticulate.
