Aganope heptaphylla (L.) Polhill

         Woody climbers. Twigs 6–8 mm diam., lenticellate, striate, thinly strigose or glabrescent in the lower part. Stipules caducous. Leaves with 5–7 leaflets; petiole 6.5–10.5 cm long, striate, lenticellate, glabrous, articulate at the base; rachis 5–10.5 cm long, striate, glabrous; pulvinus 5–10 mm long, glabrous, stipellae absent. Leaflets subcoriaceous, terminal one elliptic, 9.5 –17.5 by 6 –9.5 cm, length/width ratio 1.5–1.9, base obtuse to rounded, apex slightly acuminate, acumen up to 10 mm long, rounded, upper and lower surface glabrous, midrib raised in a furrow above, distinctly raised below, veins raised above and below, 8–10 per side, 8–25 mm apart, not reaching the margin but curving towards the apex, sometimes anastomosing near the margin, venation reticulate; lateral leaflets mostly like terminal one, elliptic to ovate, 9.7–16 by 6–7.5 cm, length/width ratio 1.5–2; pulvinus 7–9.5 mm long, thinly strigose to glabrous. Inflorescences axillary or terminal panicles, much branched, up to 30 cm long or more, peduncle 3–7 cm long, (thinly) sericeous, lenticellate; primary or secondary lateral branches 1.5–22 cm long, articulating with the inflorescence rachis. Bracts subtending lateral branches ovate to triangular, 1.1–1.3 by 0.9–1 mm, caducous, outside (thinly) sericeous, inside glabrous; bracts subtending flowers ovate, 1–1.5 by 0.7–0.8 mm, caducous, outside sericeous, inside glabrous. Pedicels 5–6 mm long, sericeous. Bracteoles at the top of pedicels, minute, ovate, 0.35–0.8 by 0.3–0.7 mm, caducous, outside sericeous, inside glabrous. Calyx greenish, cup-shaped, 6–6.5 mm high, inserted on a funnel-shaped receptacle, 2–2.5 mm high; upper lip triangular, 0.7–0.8 by 2.5–3 mm, sometimes indistinct, lateral lobes short and broadly triangular, 0.5–0.7 by 4.5 –5.5 mm, sometimes indistinct; lower lobe short triangular, ca. 0.5 by 2–2.5 mm, outside sericeous, inside glabrous. Corolla whitish or pale greenish. Standard: claw 2–3.5 mm long; blade broadly obovate or orbicular, 13–14.5 by 13–15 mm, apex slightly emarginate, both sides glabrous, with large basal callosities and thickened above the center of the petal. Wings: claw 1.5–2 mm long; blade spathulate, slightly oblique, 9.5–11 by 3–3.6 mm, apex rounded, curved upward, both sides glabrous, upper auricle and lower auricle absent, lateral pocket sometimes present, 2–3 mm long. Keel petals: claw 3–3.2 mm long; blade boat-shaped, 8.6–10.2 by 4.5–5 mm, apex rounded, both sides glabrous, upper auricle indistinct, lateral pocket 4–4.5 mm long. Stamens diadelphous, 10–11.5 mm long, free part 2.5–4 mm long, in two lengths, longer ones alternating with shorter ones, hairy, usually persistent during pod maturation; anthers 1.5–2.8 by 0.4–0.5 mm, hairy. Disc 9 or 10 glands, 0.7–0.8 mm high, hairy. Ovary 9–9.5 mm long, stipe ca. 0.5 mm long, sericeous; ovules 5–9; style 5–6 mm long, sericeous throughout. Pods variable in shape but usually strap-like, flat, 4.5–19.5 by 2.5–3.8 cm, glabrescent, distinctly sinuate between the seeds, with wing along the upper suture only, 2–4 mm wide; seed chamber absent. Seeds narrowly bean-shaped, 21–22 by 8–9 by ca. 0.5 mm; hilum eccentric, ca. 2 mm long.
