Type

Panama. Darién: Río Tucutí, between Tucutí and Río Urogantí, 25 July 1962, Duke & Dwyer 5279 (holotype MO; photo of holotype MEXU)

Morphology General Habit

Tree to 15(- 30) m, to 30 cm in diameter; crown, bark, slash, and wood characteristics not known; internodes of juvenile branchlets hollow with vertically oblong holes probably made by ants

Morphology Leaves

Leaves opposite, (3 -) 5 (- 7)-foliolate; vegetative parts glabrous; leaf axis 6.5 - 14 (- 23.5) cm long, petiole to as long as the rachis; stipules triangular to broadly ovate, 8 - 10 mm long, caducous; stipels not seen; juvenile petiolule bases without food bodies; leaflets elliptic to broadly elliptic, distal leaflet often larger than others, (5 -) 9 - 15(- 22) x 5.5 - 7.5(- 12.5) cm, base rounded, apex acuminate, veinlets in areoles with sharp edges, not intermixed with dots, primary vein flush with upper surface, blade coriaceous, glossy

Morphology Reproductive morphology Inflorescences

Inflorescences of erect, axillary, simple (30 -)42 - 70-flowered racemes (occasionally with secondary branching), with up to three inflorescences per leaf axil; inflorescence axis thick, furrowed, with prominent ledge-like scars remaining after pedicels drop, glabrous, to 11 cm long including a peduncle to 2 cm long

Morphology Reproductive morphology Flowers

Flowers not seen

Morphology Reproductive morphology Fruits

Samara narrowly elliptic to elliptic or ovate, 11 - 18 x 5 - 8 cm, base rounded, apex acuminate, glabrous; exocarp hard, glossy; stipe 1 - 1.5 cm long; seed not observed.

Distribution

The species has its main distribution in Darien, Panama and in Antioquia, Colombia, but is also scattered throughout Choc6 in Colombia, Barinas in Venezuela, and Barro Colorado Island in Panama.

Ecology

Platymiscium darienense has been collected in rain forest and along river banks, at 0 - 600 m.

Conservation

VU A3cd - vulnerable because of a population size reduction of 80% over the next 10 years due to a decline in area of occupancy, extent of occurrence and/or quality of habitat, and due to actual and potential levels of exploitation.

Phenology

Fruiting specimens have been collected from December to March and from June to August in Colombia, from June to November in Panama, and in April in Venezuela.

Vernacular

Roble (Venezuela).

Note

Platymiscium darienense has by far the largest fruits recorded in the genus, 11 - 18 x 5 - 8 cm. They have an unusually hard and glossy exocarp. In other respects P. darienense is similar to both P. stipulare and P. pinnatum. It shares robust, erect inflorescence axes carrying ledge-like pedicel scars with P. stipulare, and glabrous vegetative and reproductive parts, and leaf size and shape with P. pinnatum. Since the flowers of Platymiscium darienense are unknown, it is of great importance to collect some, ideally from the type locality and/or from the same individuals from which fruits have been collected already.
