Shrubs, up to 1 m high; young shoots tomentose; branches glabrous. Leaves opposite and subopposite, broadly elliptic-ovate to ovate-lanceolate, slightly asymmetric, rounded or narrowed at base, undulate along margins, obtuse at apex, 4 - 17 x 3 - 9 cm, coriaceous, glabrous; lateral nerves 4 - 6 pairs; petioles 5 - 10 mm long, glabrous. Inflorescences axillary; peduncles 2 or 3 together, 3 - 3.5 mm long; involucral bracts 4, foliaceous, ovate-lanceolate, 1.5 - 2 x 0.6 - 0.8 cm; flower buds 1.8 - 2.3 cm long, densely rusty anvil hairy. Flowers sessile, 2 - 2.5 cm long, red. Calyculus 5-toothed. Petals ca 1.3 cm long, red; tube almost splitting up to base; lobes 5, linear, 0.8 - 1 cm long. Stamens recurved; filaments 2 - 3 mm long; anthers elliptic-oblong; anther- thecae 2 pairs, 1.5 - 2 mm long. Ovary subglobose, 3 - 3.5 mm long; style tetragonous; stigma broadly conical-capitate, papillate. Fruits broadly ellipsoid, densely cinnamomeous strigose- hairy, crowned by persistent enlarged calyculus, 5.5 - 5.8 x 2.8 - 3 mm, orange-red.
