Usually a small tree but occasionally exceeding 30 cm dbh.
Young leaf bearing twigs longitudinally grooved and densely clothed in brown hairs. Leaflet blades about 6-17 x 2-5 cm, unequal-sided, particularly towards the base. Midrib raised on the upper surface. Stipule-like scale leaves usually present on the twigs. Rhachis of the compound leaf ends in a short, awl-like point.
Calyx pubescent or glabrous. Petals about 2 mm long. Stamens usually eight, filaments hairy. Disk continuous, surrounding the ovary and base of the staminal filaments.
Capsules about 12-24 x 10-20 mm, 3-valved, hairy inside and out. Seeds about 8-10 x 5-6 mm. Aril small and basal.
Cotyledons obovate, fleshy, apex acute, hairy on the upper surface towards the base, three indistinct veins radiate from the petiole. First pair of leaves, petiole and compound leaf rhachis winged and clothed in short brown hairs. At the tenth leaf stage: leaflet blades ovate, apex acute, margin serrate, teeth irregular along upper 3/4 of the leaflet blade, hairy on the upper surface at least along the midrib.
Distribution and Ecology
Endemic to NEQ, restricted to the area between Cooktown and Mt Molloy. Altitudinal range from near sea level to 600 m. Grows as an understory tree in well developed lowland and upland rain forest. Jagera javanica ssp. javanica occurs in Malesia.
An open crowned tree with attractive pinnate foliage that deserves a trial in horticulture. Flowers are in large terminal panicles.
