Description

Woody vine or less often shrub, to ca. 5 m long. Stems terete, hirtellous, glabrescent, lenticellate when mature, ca. 5 mm in diameter; cross section with a single vascular cylinder. Stipules triangular, ca. 1 mm long, persistent. Leaves pinnately 7-9-foliolate, lower pair of leaflets trifoliolate; petioles marginate to nearly terete, hirtellous, 3-27 mm long; primary and secondary rachides winged, hirtellous, primary rachis longer than the petiole; leaflets sessile, chartaceous, glabrous or puberulent along the prominent venation, remote repando-dentate, the abaxial surface lighter than the adaxial one; distal leaflet rhombate, attenuate at base, obtuse or acute at apex, 2.8-4 × 1.3-2.2 cm; lateral leaflets elliptic, oblanceolate, subcuneate, slightly asymmetrical, the base acute or acuminate, the apex obtuse or acute. Thyrses axillary racemiform, solitary, with hirtellous axis; cincinni few-flowered, nearly sessile. Calyx puberulent; sepals 5, oblong, concave, ciliolate on margins, outer sepals ca. 0.7 mm long, inner sepals ca. 2 mm long; petals obovate, ca. 2.5 mm long; disc of 2rounded lobes. Capsules red, ciliate on margins, coriaceous, trigonous with ellipsoid outline, stipitate, with 3 narrow, dorsal wings when young, sometimes becoming trigonous and wingless when mature; endocarp minutely velvety pubescent. Seed one per fruit, dark brown, with a thick, white, bilobed sarcotesta on lower ½.

Distribution

Guianas present, Northeastern Brazil present, Trinidad present
Known from the Guianas, Trinidad, and northeastern Brazil. Perhaps not distinctive from Paullinia micrantha Cambess., a name that have been applied to some collections of P. dasygonia Radlk. in the Guianas (GU: 1; SU: 3; FG: 4).
