Shrub or small tree, up to 4 m tall, much branched; terminal branchlets terete or slightly quadrangular, 3-7 mm in diam., somewhat succulent, glabrous, soon covered with a buff corky bark. Stipules free, oblong-ovate, 7-12
7-9 mm, obtuse and entire when young (apical and distal nodes), later splitting into two lobes at older nodes, each lobe oblong-ovate, 4-9 mm long, shortly apiculate, soon corky, persistent or fragmenting. Leaves with petioles 1.0-3.5 cm long, glabrous; blades elliptic to oblong-elliptic, 12-22
5.5-10 cm, acute at base, acute at base, acuminate at apex, acumen narrowly triangular, 0.7-1.2 cm long, papyraceous to subcoriaceous, drying dark brown above and pale brown below, glabrous throughout; secondary veins 10-13 on each side of midrib, curving towards the margin and almost reaching it; tertiary veins rather densely and prominently reticulate in the dry state; domatia absent. Inflorescence capitate, short-pedunculate; peduncle 0.5-1.7 cm long, glabrous; head included in a large involucral structure, 5.5-9.0 cm long, green at base and pinkish-red at apex, formed by the basally fused bracts, glabrous; involucral basal portion urceolate, 2.5-5.7
1.0-1.7 cm; bracteoles ligulate to linear, 0.7-1.5 mm, glabrous. Flowers 5-merous, (heterostylous?), pedicellate; pedicels 1.0-3.5 mm long (5-7 mm long in mature fruits), glabrous. Hypanthium narrowly cylindrical, ca 1 mm long, glabrous. Disk bilobed to the base, ca 1 mm long. Calyx cupular, dentate, 1.0-1.7 mm long, glabrous; tube 0.7-1.0 mm long; teeth deltoid to narrowly triangular, 0.3-0.7 mm long. Corolla narrowly tubular, 18-31.5 mm long, glabrous, white; tube narrowly cylindrical, 17-30 mm long, 1.5-2.5 mm wide, glabrous outside, with a sericeous ring just above the base and glabrous above inside; lobes narrowly ovate, 1.0-1.5

This species is remarkable by its large, urn-shaped involucre, varying from bilobed to unequally 4-lobed, which is formed by the fusion of the external bracts. The involucre is reported to be red (

, which are quite similar in vegetative characters. Due to the small number of collections, it is not known whether the flowers of this species are heterostylous. In the few flowers that we analyzed, the stamens are included and the style is barely exserted, which is consistent with a long-styled form.
