The internodes are 2–3 cm long. The glabrous, coriaceous, ovate to elliptic leaves with an entire margin are (3–)7–14.5 cm long, and (2–)3.5–9 cm wide. The pinnate leaf venation is impressed above, and is prominent on the abaxial leaf surface. The glabrous petiole is 2–6 mm long. Generative characteristics The axillary or terminal, racemose inflorescence with an up to 4 cm long rhachis bears 2–7(–8) fleshy, waxy, nectariferous, pedicellate, tubular, vibrant, orange-red, green-tipped flowers with 9–25(–33) mm long pedicels. The five-winged, obconical, 0.8–1 cm long, and 0.6 cm wide calyx has five acute teeth. The tubular, fused, urceolate, pentagonal corolla is 1.7 cm long, and 0.4–0.5 cm wide.
