Sindora siamensis var. siamensis


Tree. Leaves (2- or 1-) 3- or 4-jugate; petiole 3-4 cm and rachis up to c. 10.5 cm long, both puberulous, glabrescent. Stipules foliaceous, falcate, up to c. 18 mm long, acuminate, rounded auriculate at base, reticulate and puberulous on both surfaces, caducous. Inflorescences paniculate, up to 27(-35) cm long, lateral branches up to c. 6( — 12) cm long, both rachis and branches densely puberulous or pubescent; bracts foliaceous, broadly ovate, 4-7 mm long, puberulous on both surfaces, persistent; bracteoles ovate to lanceolate, c. 5 mm long, puberulous on both surfaces, persistent; pedicels up to c. 4 mm, puberulous. Petal elliptic or slightly oblong-elliptic, 7-9 by 2.5-3 mm, fleshy, woolly outside, glabrous inside. Stamens: the united basal parts of filaments very short; free filaments 15-20 mm, slightly hairy at the lower part; fertile anthers various in size, the larger ones ovoid- ellipsoid, 3-3.5 mm long, the others smaller. Ovary subsessile, ellipsoid, flattend, c. 4.5 mm long, densely hirsute, with minute, spiny outergrowths, 3-8-ovuled; style up to c. 15 mm, recurvate, glabrous or sparsely hairy in the basal part; stigma capitate. Seeds on top of a large aril, orbicular or broadly ellipsoid, flattened, 15-25 by 14 by 17 mm; aril (dry) cushion-shaped, c. 10 by 15 mm, irregular on the surface.

In var. siamensis the upper surface of the leaflet is minutely thinly puberulous and slightly rough to the touch. It is very characteristic and can be used to recognize the plants of this variety from other taxa in Sindora. There is only one collection of Sindora siamensis from the Malesian area, made by Ridley in Kelantan (cf. Whitmore, I.e.).


The wood is used for planking. See
