Petiole slender, up to 3 cm long, ca 1 mm in diameter, pilose, swollen at base; rachis up to 20 cm long, slender, pilose. Leaflets 3 or 5, alternate or sub-opposite, rigidly chartaceous, ovate-oblong or elliptical, 8—15 x 3.5—6.0 cm, base obtusely cuneate, apex acute; upper surface smooth, glabrous, midrib straight, impressed, lower surface partly pilose, midrib prominent, pilose, lateral nerves 6—10 pairs, prominulous, irregularly spaced, curved and anastomosing towards margin, secondary nerves prominulously reticulate, tertiary nerves inconspicuous; petiolule ca 5 mm long, somewhat thickened at base. Flowers unknown. Infructescence a simple, axillary, solitary, laxly pilose, glabrescent ra- ceme; rachis slender, 9—20 cm long. Persistent calyx lobes rotundate, glabrous, rather ciliate, 0.5—0.8 mm in diameter. Fruit 4—5-celled, pericarp 1.5—2.0 mm thick, the partitional septa subcoriaceous. Seed one in each cell, 1.5—2.5 cm long and 1.5—2.0 cm in diameter, testa chartaceous; only one to three seeds developing, the other half filled with a dirty white arillus or undeveloped seed which is edible and sweetish. TYPUS: Kostermans 19117 (BO). DISTRIBUTION — Island of Sumbawa VERNACULAR NAME — Kaju narab (W. Sumbawa). The species is named in honour of Dr. A.J.G.H. Kostermans, who collect- ed ample material in Sumbawa, where he recognized it immediately as an undescribed species. *) A MSS. of Lansium is almost completed. **) Assistant, Herbarium Bogoriense; h.t.
