Caciqui, Cucua Dioecious tree, 8-20 (30) m tall; branchlets slender, weakly flexuous, soon glabrous; sap white. Leaves alternate, distichous; petioles 3-10 mm long; stipules very narrowly lanceolate, long-acuminate, fully amplexicaul, mostly 5-7 mm long, rarely to 2 cm; blades +/- oblong-elliptic, acuminate to caudate-acuminate at apex, acute to obtuse at base, 9-15 (17) cm long, 3-5 (6) cm wide, glabrous or nearly so. Flowers unisexual; staminate inflorescences in discoid, usually paired, sessile or subsessile heads 8-10 mm diam, the bracts broadly obtuse, minutely puberulent, in 2-4 series, the bracteoles interspersed with flowers; perianth vestigial; stamen solitary, to 3 mm long; anthers +/- oblong, basifixed, apiculate. Pistillate flowers ovoid, solitary, sessile, involucrate, ca 2 mm diam, the bracts in 3-6 series, imbricate, softly puberulent; perianth tubular, 2-2.5 mm long, minutely 4-lobed; ovary inferior to semi-inferior; style to 1.5 mm long; stigmas 2, 4-6 mm long, widely exserted. Fruits false drupes, globose to cylindroid, 9-14 mm long, red; mesocarp thin. Croat 11935. Rare; seen only once. The BCI collection is sterile, but almost certainly represents this species. Descriptions of the flowers and fruits were based on the Flora of Panama (Woodson & Schery, 1960) and on herbarium material from Central America. Flowers elsewhere from January to May, with the fruits maturing from February to June.
