Leaves opposite, sometimes alternate towards the stem-base; lamina narrowly ovate to ovate in outline, 1.5–5.5 cm. long, 1.5–5 cm. wide, cordate, 3-partite to 3-foliolate (sometimes much dissected, giving several subopposite pairs of pinnae plus the terminal one), with a larger middle section of the leaflet, sometimes only shallowly 3-lobed or pinnatifid to pinnatisect; segments or pinnae somewhat rhombic in outline, almost unlobed to pinnatipartite, the margin crenate, the hairs scattered and often restricted to the margins and veins; petiole 2–8(–12) cm. long; stipules narrowly to broadly ovate, 5–10 mm. long, 2–7 mm. wide, acute to apiculate at the apex, membranous.. Inflorescence a terminal simple umbel of 2–4(–5) flowers or the flowers sometimessolitary; peduncle 5–9(–13) cm. long, leaf-opposed or in the axil of the smaller of the 2 apparently opposite leaves; pedicels 1–3 mm. long; bracts 4–8 per node, lanceolate, acute, membranous, 5–8 mm. long, 1.5–3 mm. wide.. Sepals lanceolate, 9–14 mm. long, 1–4 mm. wide, acuminate, glandular and sparsely pubescent, with conspicuous red veins.. Spur 5–15(–20) mm. long.. Petals 4, oblanceolate and unguiculate to ± spathulate, pink with red veins, the 2 posterior ones 9–20 mm. long, 3–5.5 mm. wide, generally longer than the anterior ones; the anterior ones 9–15 mm. long, 2–4 mm. wide.. Stamens connate at the base for l–2.5(–5) mm.; antheriferous filaments 7, 5–12 (–16) mm. long, white below and pink towards the tip; staminodes 3, 2.5–6.5 mm. long, mostly white throughout; anthers 2–2.5 mm. long, ± 1 mm. wide.. Ovary with basal part tomentose; rostrum pubescent; style 3–8 mm. long; stigmas 1.5–3 mm. long, pink.. Fruit 3–4 cm. long; mericarps 5–7 mm. long, 1.5–2 mm. wide..
