Aspidopterys concava (Wall.) A.Juss.

Liana, up to c. 20 m long. Young parts dark red-haired, twigs angular when young, more terete when older, leaf scars somewhat thickened; internodes (5-)7-10(-15) cm, with irregular, longitudinal ridges and few lenticels, glabrous, dull brown. Leaves subcoriaceous, ovate-elliptic to ovate-oblong, 1.25-2.5 times as long as broad, (5-)7-10(-12) by 3-5(-8) cm; base rounded to acute, rarely subcordate, top mostly obtusely acuminate, rarely cuneate-emarginate or wholly rounded; surfaces glabrous, but basal part of the midrib below haired as is the petiole; nerves 4-7 pairs, slightly prominent; petiole ¾-1½(-2) cm. Inflorescences (2-)5-10 cm long; axes thin, terete and dark red-brown haired. Pedicels thin, glabrous except below the bracteoles, in flower 1-1½ cm, in fruit 3-5 cm, articulated in the lower half. Bracteoles alternate below the articulation. Flowers white, ovate-elliptic in bud. Sepals 2 by 1 mm, glabrous, top rounded. Petals oblong, 3.5-6 by 1½-3 mm, glabrous, with rounded top. Ovary glabrous, styles 3-4½ mm. Carpophore almost absent, disk lobes forming a sort of cup (Fig. 1a). Samara: main wing suborbicular, ovate or transverse-elliptic, concave outside, 2-3.5 by 2½-4 cm, scarious and pale-translucent; dorsal wing distinct but small, broadest at the base. Seed acroscopically situated in the wing, linear, 3-5 mm long.

In forests, below 500 m. Fl. (mostly) Jan.-Feb., fr. March-April. It seems that during flowering and fruiting often a good deal of the leaves have fallen.
