Description

Shrubs to 3 m tall, the branchlets ultimately obtusely angular, smooth, gla- brous, the lenticels minute, few. Leaves oblong, 6.5-13.0 cm long, 3.5-7.0 cm wide, obtuse, rotund or widely deltoid at the apex, rounded or obtuse at the base, acuminate, the acumen short, to 0.5 cm long, acute or obtuse, the costa promi- nulous above and beneath, the lateral veins 7-8, widely arcuate, forming an undulate submarginal vein, the intermediate veins 1-4, soon branching; petioles moderately slender, stiff, glabrous, 1.0-2.5 cm long, to 0.12 cm wide; stipules often short connate, persistent, hemispherical, turgid, to 0.4 cm long, each part with 2 awns. Inflorescences solitary, terminal, cymose paniculate, to 6.5 cm long, to 5.5 cm wide, the peduncle to 2.5 cm long, the lowermost branches few, 1-3, opposite or verticillate, to 3 cm long, the flowers terminal, few. Flowers sessile; hypanthium subrotund, ca. 1 mm long, shiny, glabrous, the calycine cup to 0.5 mm long, subturgid, petaloid, glabrous, eglandular within; corolla pink, the tube narrow cylindrical, ca. 15 mm long, wider above the middle, puberulent inside and out, petaloid, the lobes 5, linear subulate, ca. 10 mm long, 1 mm wide at base, the margins contiguous above the middle, flat, venose near the mouth, petaloid; stamens 5, the anthers narrowly oblong, 3.3 mm long, subacute, not exserted, the filaments short, 1.1 mm long, attached above the middle of the tube; ovarian disc 0.4 mm long, 0.9 mm wide, the style slender, 15 mm long, the stigmas 2, subulate, 1.5 mm long.

Note
|
It is closely related to Coussarea nebulosa Dwyer which also has connate stipules with awns, few lateral veins in the leaf blades and a very reduced calycine cup. Coussarea roseo-cremea, however, is a lowland species with pink flowers, small- er anthers and corolla lobes almost equal to the corolla tube in length. The Latin name roseo-cremea refers to the flower color.
