Cyphia lasiandra Diels

Twining and climbing herb, well-developed plants forming tangling masses, usually more than 1 m. and up to several m. long, from a subglobose tuber ± 2–3 cm. in diameter; stems sparsely branched, ribbed, glabrous or sparsely puberulous in the inflorescence region only.. Leaves petiolate, up to 30–100 mm. long, (3–)6–40(–55) mm. wide, linear to ovate, acute to acuminate or rarely ± obtuse at the apex, attenuate to truncate or subcordate at the base, serrate, glabrous or rarely shortly pubescent above; venation prominent beneath; petiole 1.5–25 mm. long, often curved.. Raceme twining, usually very lax, often more than 50 cm. long, sometimes with ± short and few-flowered branches below; pedicels 2–10(–20) mm. long, very finely crisped pubescent to almost glabrous; bracts leaf-like, diminishing in size upwards; bracteoles 0.8–5 mm. long, filiform to lanceolate-acuminate, sometimes denticulate.. Hypanthium broadly obconical, 10-nerved, shortly pubescent to glabrous.. Calyx-lobes narrowly triangular, erect to reflexed, 1.5–4 mm. or up 10 mm. long in fruit, with 1–5 pairs of teeth at the margin, glabrous.. Corolla 9–17 mm. long, pale pink to purple or almost white, ± saccate at the base, split to the base into 2 lips, the upper 3-lobed but finally ± disintegrating, the lower divided into 2 free petals; all petals linear, glabrous or sparsely pubescent outside, white pubescent inside, at least on the lower half.. Stamens 4–8 mm. long; filaments linear, dilated and connate at the base, ± pubescent; anthers elliptic-oblong, 2–3.2 mm. long, lanate with curled hairs ± 1.2-1.5 mm. long on the back of the connective, and at the tip with a tuft of hairs 0.2–0.5 mm. long.. Ovary semi-inferior; style 2.5–5.5 mm. long.. Capsule ovoid to subglobose; inferior part 3–5.5 mm. long, membranous, with 10 distinct nerves connected by weak transverse nerves; valves 2.5–5 mm. long.. Seeds ± broadly elliptic in outline, ± compressed or irregularly angular, ± 0.8–1.6 mm. long, coarsely reticulate, brown.
