Stems red, 4-lined when young, soon 2-lined to terete except immediately below nodes (4-lined); internodes 8-43 mm, shorter than to exceeding leaves; bark greyish-brown. Leaves petiolate, with petiole 1-2.5 mm long; lamina 22-60 x 7-36 mm, oblong-lanceolate or rarely lanceolate to oblong-ovate or ovate, acute to rounded-apiculate or very rarely rounded, margin plane, not incrassate, base cuneate to rounded, paler beneath, not glaucous, subcoriaceous; venation: 4 pairs main laterals, with midrib branched distally, and distinctly visible lax tertiary reticulum; laminar glands medium to short streaks and dots; ventral glands ± dense. Inflorescence 1-8-flowered, from 1-2 nodes, corymbiform, some- times with shorter apical internode, without flowering branches from middle part of stem; pedicels 2-5 mm long; bracts narrowly elliptic to narrowly oblong, deciduous. Flowers 45-60 mm in diam., stellate to slightly cyathiform; buds broadly ovoid to subglobose, obtuse. Sepals 7-10 x 6-10 mm, free, imbricate, unequal, broadly oblong-elliptic to subcircular, rounded, erect in bud, ± spreading in fruit, with margin ciliate or ciliolate, scarious, often with submarginal red zone; midrib obscure or indistinct, veins not prominent; laminar glands linear, numerous. Petals bright yellow, not tinged red, spreading or ± incurved, 21-30 x 15-20 mm, c. 3 x sepals, obovate, with apiculus subterminal to lateral, rounded; margin entire or ciliate, with few inframarginal gland dots. Stamen fascicles each with c. 50-70 stamens, longest 12-18 long, c. 0.5-0.75 x petals; anthers reddish. Ovary 6.5-9 x 5-6 mm, ovoid to ovoid-conic; styles 8-11 mm long, 1-1.5 x ovary, erect, outcurved at apex; stigmas not capitate. Capsule 9-12 x 9-11 mm, broadly ovoid.
