Description

Shrubs or small trees, to 5 m tall, the branchlets terete, glabrous, ashen gray when dry, the nodes well spaced. Leaves oblong or lanceolate, 6.5-25.0 cm long, 2.0-13.5 cm wide, scarcely or strongly inequilateral, often falcate, acuminate, the acumen straight or curved, to 1.5 cm long, obtuse, cuneate at the base or some- times obtuse or lightly auriculate, the costa subplane to prominulous above, prominulous beneath, the lateral veins 6-9, widely arcuate, the venules 1-3 be- tween adjacent lateral veins, these branching and reticulate, the petioles lacking or to 0.5 cm long, glabrous; stipules triangular, to 4 mm long, rounded toward the apex, glabrous. Inflorescences solitary, terminal, glabrous to puberulent, thrysoid paniculate, to 6 cm long, to 4.5 cm wide; peduncle slender, 1-2 cm long, the primary branches alternate or opposite, to 2 cm long, ascending, the rachis often with 2 pairs of terminal branches, alternate or opposite, flabellate in ap- pearance, the flowers congested, sessile or subsessile. Flowers with the hypan- -thium oblong or oblong rotund, often shorter than the calyx cup, the latter cylin- drical or collar shaped, 1.5-2.5 mm long, truncate, stiffly petaloid, glabrous or

Note
|
Most of the material cited below has previously been erroneously assigned to Cous- sarea impetiolaris Donnell Smith which unlike this species has subquadran- gular branches, a corolla tube up to 2 mm in width, much more elongate anthers which are up to 8 mm long, and a fruit which in the dried condition is about 19 mm long. The type of Coussarea impetiolaris is Pittier 134008 (US, syntype) from Costa Rica. Most fruits on herbarium material have only the fibrous endocarp visible. One collection, Dwyer 2012 (MO) shows the fleshy outside of the fruit still present. These fruits measure to 1.5 cm in length; those with only the endocarp present measure to 1.2 cm in length.
