Characteristics

Herb up to 50 cm. tall, rhizomatous; stems ascending, unbranched, 1.5–4 mm. thick, whitish to sometimes yellowish puberulous or hirtellous, the lower part woody.. Leaves in spirals, crowded at the apex of the stem; lamina chartaceous when dry, oblanceolate to obovate, (1–)3–14 × (0.5–)1–6 cm., apex acute to obtuse, base obtuse to subcordate or occasionally cuneate, margin repand to faintly or sometimes coarsely dentate; upper surface smooth or ± scabrous, lower surface scabrous or smooth and puberulous to hirtellous on the main veins; lateral veins 3–8(–10) pairs; petiole 0.2–1.3 cm. long, 0.5–1.5 mm. thick; stipules either triangular, ± 0.1 mm. long and caducous, or subulate, 4–10 mm. long and persistent.. Inflorescences solitary; peduncle 0.6–2.7 cm. long, gradually passing into the receptacle.. Receptacle zygomorphic to almost actinomorphic, naviculate to broadly funnel-shaped and orbicular in outline; flowering face linear, elliptic or subrhombic to subcircular, 0.5–2.2 × 0.4–1 cm., plane, often dark purplish, margin 0.1–1.5 mm. wide, often with a ridge bordering the flowering face; primary appendages 2, terminal (in actinomorphic inflorescences hardly distinct from secondary appendages), linear, 7–45 mm. long, secondary appendages 10–33, lateral, triangular to linear, (0.2–)1–17 mm. long.. Staminate flowers ± spaced; perianth-lobes 2–3; stamens 2–3.. Pistillate flowers up to ± 10; perianth tubular; stigmas 2.. Endocarp-body tetrahedral, ± 2.5 mm. in diameter, two sides tuberculate.
