Morphological description (blancoi Crudia all BBGB18 f2 )
Tree to 28 m high. Stipules intrapetiolar, minute.
Leaves 7-9-foliolate, shortly petioled; petiole and rachis 5-11.5 cm long, prolonged c. 5 mm beyond the top leaflet; petiolules very short, 1-2 mm, glabrous. Leaflets chartaceous, ovate or elliptic-ovate 4-9(-21) by 1.5-3(-7) cm; apex shortly acuminate to acuminate; base obtuse or rotund, slightly asymmetric; sparsely puberulous or almost glabrous above, minutely, loosely, appressedly puberulous, glabrescent (or almost glabrous except on the midrib) beneath; nerves 5-8, sometimes more per side.
Inflorescences racemose, axillary or terminal, usually erect, 13-17(-27) cm long, the rachis puberulous, rather densely flowered; bracts caducous or absent, if present then ovate or triangular, up to 5 mm long, glabrous; bracteoles very small, subulate, 0.35-1 mm long; pedicels 2-3.3(-6 ?) mm, articulated at the apex, puberulous.
Flowers white, puberulous, glabrescent, or almost glabrous outside. Hypanthium c. 1 mm long. Calyx lobes ovate, broadly elliptic, elliptic, or obovate, 3-4 by 1.5-2.5 mm, usually puberulous inside. Stamens 10; filaments 5-7 mm, usually glabrous; anthers 0.75 mm long. Pistil shortly stipitate; stipe c. 0.5 mm long, free, glabrous; ovary c. 3 mm long, 2- or 3-ovuled; style short, 1-2.5 mm, glabrous or slightly hairy at the basal part; stigma indistinguishable.
Pods solitary or a few together, ellipsoid or broadly ellipsoid, 2.5-4 by 1.5-2 cm, usually 1-seeded.
Seeds only very young one seen.
Distribution
Malesia: Philippines (Luzon), Moluccas (Tanimbar Island), and Papua New Guinea (Western Prov.).
Habitat & Ecology
In thickets, savanna riverside vegetation, and in primary forests, chiefly along streams at low and medium altitude Fl. July.
Note
The flowers of this species have a very short style, 1-2.5 mm long. De Wit (1950: 419) correctly recorded the length of the style as '2 to 2.5 mm long' in the description, but it was erroneously drawn in Fig. 2 as long as 8-10 mm (blancoi Crudia all BBGB18 f2 ).
