Leaves triangular-ovate, lower ± 8 × 4 mm., upper 20 × 8 mm., forming an involucre around the spadix.
Inflorescence-bearing stems appearing a few cm. above soil-surface with their bright red, flowering upper parts, 5–20 cm. long from tuber.
Tuber trailing 10–15 cm. below soil surface, 20 cm. or more long, 0.6–0.8 (1–1.5 in swollen part) cm. in diameter, minutely pilose.
Flowers apparently ebracteate or ♂ subtended by minute reduced bracts.
Inflorescence 2.8–3 × 3.2–3.9 cm., ♂ spadices depressed-hemispherical, ♀ spadices hemispherical.
Female flowers 3 mm. long, ovary with perianth ± 2 mm., style 1–1.5 mm.
Male flowers, including pedicel, up to 1.5 cm. long with perianth-segments ± 3 mm. long and synandrium 5–6 mm. long.
Infructescence dark red, fleshy, ovoid, with spadix strongly swelling above involucre.
Seeds 0.75–1.5 mm long, ellipsoid, creamy.
Infructescence 2.5–3.5 cm diameter, dull reddish-black to crimson, looking like a strawberry.
Female flowers: perianth 1–1.5 mm long; style 2–3 mm long, filiform.
Male flowers 8–15 mm long; perianth segments 2–4, lanceolate, acute; stamens 2–6 in cylindrical synandrium, anthers whitish-cream.
Bracts 5–30 × 3–11 mm, ovate to lanceolate, acute to acuminate, margins irregularly and obscurely serrulate, rigid, becoming smaller towards base of involucre and continuous with scales on peduncle, pinkish-crimson turning brown with age.
Rhizomes 3–8 mm diameter, pubescent.
Peduncles 0–13 cm tall, glabrous to pubescent (particularly in axils of scales); scales 4–10 × 2–5 mm, ovate to lanceolate, acute, margins sometimes irregularly and obscurely serrulate, rigid, glabrous.
