Shrub 1-2-1-5 m tall, rather compact, with branches erect (or ascending ?), not frondose. Stems reddish, slightly 4-angled and ancipitous when young, soon terete; internodes 10-40 mm long, shorter than to exceeding leaves; bark reddish-brown. Leaves petiolate, with petiole 0.5-2 mm, long; lamina 20-45 x 9-25 mm, ovate- lanceolate to triangular-ovate, obtuse to rounded, apiculate, margin plane, not incrassate, base ± broadly cuneate to shortly angustate, ± glaucous beneath, subcoriaceous; venation: 2(3) pairs main laterals, with midrib branched distally, without distinct tertiary reticulum; laminar glands mostly dots (short streaks towards midrib and base); ventral glands dense. Inflorescence l-16(-c. 24)-flowered, from 1-2 nodes, corymbiform, sometimes with short apical internode, without flowering branches from middle of current stem; pedicels 4-6 mm long; bracts intermediate (below first flower), narrowly elliptic, deciduous. Flowers 30-50 mm in diam., shallowly cyathiform; buds ovoid, subapiculate to obtuse. Sepals 7-11 x 5-9 mm, free, imbricate, subequal or unequal, ± spreading in bud and fruit, ovate-oblong to broadly elliptic, rounded or usually apiculate, with margin entire or usually finely eroded-denticulate, ± hyaline, midrib of outer ones distinct, veins not prominent; laminar glands linear, numerous. Petals golden yellow, not tinged red, slightly incurved, 20-26 x 19-22 mm, 2.5-3 x sepals, broadly obovate, with apiculus, subterminal, rounded; margin finely glandular-denticulate, with a row of inframarginal gland dots. Stamen fascicles each with c. 50-60 stamens, longest 8-9 mm long, c. 0.35-0.4 x petals; anthers deep yellow. Ovary 5-6 x 4-4.5 mm, long, ± broadly ovoid; styles 4-5.5 mm long, 0-9 x ovary, ± erect, outcurved towards apex; stigmas subcapitate or capitate. Capsule 9-12 x 7-9 mm, ovoid. Seeds not seen.
