Plants dioecious; inflorescence axillary. Staminate plants with numerous, minute imperfect flowers enclosed by a dehiscing two-valved, reflexed spathe, flowers with three sepals, one minute petal rudiment, one staminodium and two stamens; scapes thin, 1.0-1.3 mm wide, 10–30 mm long, flowers slightly zygomorphic, with obliquely extended stamens, hairs absent at base of androecium, staminodia adnate near the apex of the fused stigmatic lobes, with lobes shallowly cleft and conspicuously fringed. Pistillate plants with inflorescence subtended by a bivalve spathe; scapes long, extended to spirally coiled; flowers solitary, slightly zygomorphic, with three sepals 2.0–3.5 mm long, three minute transparent petal rudiments, three staminodia and three bifid stigmas borne on short, or highly reduced styles; staminodia small, inconspicuous, adnate to fused discordant stigmatic lobes; stigmas fringed; floral incision deepest between matching stigmatic lobes. Ovary inferior, unilocular; fruit elongate, approx. 9.5–10.0 cm long, ellipsoid, indehiscent; placentation parietal; seeds numerous, ellipsoid, striate, 1.3–2.0 mm long; endosperm absent (Lowden, 1982). |
