Stems orange to vinous red, 4-lined and ancipitous when young, soon 2-lined, eventually terete, internodes shorter than leaves; cortex exfoliating in strips; bark reddish brown, finely striate. Leaves sessile or with petioles to 0.2 mm long; lamina 12-16 x 3.5-6 mm, lanceolate to narrowly oblong or elliptic-oblong, paler beneath, chartaceous, not glaucous, with margins plane or recurved (in drying?), spreading; apex acute to apiculate or obtuse, margin entire, base cuneate to subcordate; venation: 3(4) pairs of laterals curved- ascending from lower 0.3-0.35 of midrib, tertiary reticulation dense; laminar glands pale, dense, unequal, not prominent; intramarginal glands black, dense. Inflorescence c. 3-5-flowered from up to 3 nodes, congested, curved-corymbiform, with irregularly disposed flowering branches from lower nodes; pedicels 1-3 mm; bracteoles reduced, narrowly lanceolate, with dense marginal black glands. Flowers c. 15 mm in diam.; buds ellipsoid, subacute. Sepals 6-7 x 1.4-1.6 mm, subequal, free, narrowly oblong to lanceolate, acute, entire; veins 5-7, branching; laminar glands pale, linear, distally interrupted to striiform; inframarginal glands black, dense. Petals golden yellow, tinged red dorsally, 8-10 x 4-4.5 mm, c. 1.7 x sepals, oblong-oblanceolate, rounded with apiculus apiculate, subapical; laminar glands mostly pale, linear to striiform or punctiform, occasionally black, solitary, punctiform; marginal glands black, slightly prominent. Stamens c. 70, longest 7-8 mm, c. 0.85 x petals; anther gland black. Ovary c. 3 x 1.5 mm, ovoid-pyramidal; styles 4.5 mm, 1 .5 x ovary, spreading-incurved. Capsule and seeds unknown.
