Radlkofer, L.A.T. (1879) Sitzungsberichte der Mathematisch-Physikalischen Classe der k. b. Akademie der Wissenschaften zu Munchen 4 : 522.
Lenticels often sparsely distributed. A cream layer is often visible beneath the subrhytidome layer before the first section of the outer blaze.
Leaflets about 6-10 in the compound leaf, each leaflet blade about 7-17 x 2.5-5.5 cm. Midrib and main lateral veins slightly raised on the upper surface. Leaflet stalk swollen at its junction with the compound leaf rhachis. Compound leaf rhachis flattened or with a slight ridge on the upper surface.
Fruit shortly stipitate, obovoid or subglobose, about 16-28 x 22-32 mm, 3-locular, orange-yellow, with a red flush. Valves reticulate when dry, glandular on the inner surface. Aril small, yellowish, basal and lateral. At maturity, seeds surrounded by a sloppy translucent fluid which can be mistaken for an aril. Cotyledons green.
First pair of true leaves ovate, midrib raised on the upper surface. At the tenth leaf stage: leaf or leaflet blades elliptic to obovate, apex acuminate, base attenuate, glabrous on the upper surface; leaflet stalks short on compound leaves, hairy; petiole and rhachis of compound leaf often winged. Seed germination time 11 to 53 days.
A tree with attractive form that can be very colourful when in fruit and deserves to be introduced to horticulture.
