Blume, C. (1847) Rumphius 3 : 131.


Usually a small tree seldom exceeding 30 cm dbh, but often flowers and fruits as a shrub and occasionally grows as a vine. Vine stem diameters to 4 cm recorded. Blaze very fibrous. Dead bark often slightly layered.


Compound leaf petiole often hairy, about 1.5-8 cm long, shallowly channelled on the upper surface. Leaflet blades about 4-13.5 x 2-7.5 cm, leaflet stalks 0-10 mm long. Midrib and main lateral veins raised on the upper surface of the leaflet blade. Terminal buds clothed in pale, +/- prostrate hairs. Twigs marked by longitudinally elongated lenticels.


Outer pair of sepals larger than the inner pair, all sepals gland-dotted. Petals about 1.5-2 x 0.5 mm, with a long, tubular claw.


Fruits about 5-6 x 4-5 mm. Seeds globular, about 4-5 mm diam., aril absent.


Cotyledons fleshy, about 8-12 x 2-4 mm. apex emarginate, base attenuate. First pair of leaves trifoliolate, the middle leaflet much larger than the lateral leaflets. Leaflet blades about 4-6 x 2-2.5 cm. At the tenth leaf stage: leaflet blade margins serrate at least from the middle to the apex, a few prostrate hairs present on the upper surface. Domatia, if present, are tufts of hair. Seed germination time 26 to 166 days.
