Dysoxylum nutans
Description
Bush with fastigiate branching or small tree to 6 m; bole to 5 cm diam.
Bark grey- brown, smooth to finely cracked; inner bark creamish, flecked white.
Leaves 20–50 cm, imparipinnate, (l–)2–3(–4)-jugate, drying yellowish; petiole 6–10 cm, c. 2 mm diam., terete, glabrescent to ± densely pilose, base slightly swollen; rachis c. 2 mm diam., glabrescent to ± pilose.
Flowers white to cream, solitary or in fascicles of up to 7; bracteoles 2 or 3, 2–3 mm long, triangular to subsepaloid, densely pilose.
Petals 5, 16–19 by 2.5 mm, valvate, fleshy, adpressed pubescent to pilose without, glabrous within, adnate to staminal tube in proximal half.
Staminal tube ± densely sericeous without, longvillous within, margin 10-lobed, each lobe irregularly bifid or toothed; anthers (9 or) 10, c. 1 mm long, narrowly oblong, ± locellate, glabrous, attached in notches between lobes, ± partially protruding from tube, subsessile.
Ovary densely long-strigose, 5-locular, each locule 2-ovulate; style terete, long sericeous in lower 5/6; stylehead short-cylindrical.
Fruit c. 2 cm long, subspherical to ellipsoid, usually ± beaked, especially when young, orange-red, densely pilose, cerebriform in sicco, 5-valved.
Seeds up to 10, usually fewer, c. 13 mm long, plano- convex, red, borne on white carpel walls.
Distribution
Asia-Tropical: Jawa (Jawa present); Lesser Sunda Is. (Bali present); Sulawesi (Sulawesi present); Sumatera (Sumatera present), Flores present, Sula Islands present, Sumbawa present
MalesiaSumatra (?, based only on Korthals’s specimens, localizations of which are often inaccurate), Java, Celebes, Lesser Sunda Islands (Bali, Sumbawa, Flores), Moluccas (Sula Islands). Cultivated at Bogor.
Morphology
Specimens with somewhat lobed leaflets have been collected in both Java and Celebes. Specimens from Celebes tend to have smaller calyces with more triangular lobes, and to be, in general, more strongly pilose than the bulk of the Javanese specimens. However, densely hairy specimens are well known from Java and specimens with intermediate calyx characters have been collected in Flores and in the Sula Islands. Nevertheless, the matter is worth further investigation.
This plant has a great superficial resemblance to D. hornei Gillespie of Fiji, but that differs in its smaller number of stamens (6) and carpels (3).
