Much-branched scrambling or straggling, bushy herb, prostrate to erect or scandent, ± 0.3–3 m. and probably more.
Morphology General Indumentum
Stem, branches and inflorescence-axis ridged, glabrous to rather densely furnished with multicellular brownish hairs.
Morphology Leaves
Leaves cordate-ovate to deltoid-lanceolate, subacute to acuminate, glabrous or with scattered multicellular hairs on the veins of the lower leaf surface; lamina of leaves from central part of stem 1.5–8 × 1–5 cm., very shortly cuneate to truncate or cordate at the base, with a slender 1–4 cm. petiole; upper and branch leaves smaller, more shortly petiolate.
Morphology Reproductive morphology Inflorescences
Inflorescence of axillary and terminal elongate thyrses 8–40 cm. long, formed of distant few- to rather many-flowered cymose clusters which may be loose with slender branches up to ± 5 mm. long or dense and congested; clusters thus varying from ± 3–18 mm. in diameter.
Morphology Reproductive morphology Inflorescences Bracts
Bracts and bracteoles lanceolate-acuminate, 1–1.5 mm., glabrous, membranous with a brownish or yellowish midrib.
Morphology Reproductive morphology Flowers Perianth
Perianth-segments oblong, ± 2.5 mm., concave and strongly hooded at the apex, glabrous, 1-nerved, pink, white or greenish, drying straw-coloured with a darker or greenish central vitta.
Morphology Reproductive morphology Flowers Androecium Stamens
Free portion of filament longer than the sheath, sinuses slightly rounded with no intermediate teeth.

Stigmas 2(–3), 0.75 mm., divergent.
Morphology Reproductive morphology Flowers Gynoecium Style
Style practically absent.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2–4-ovulate, thickened above.
Morphology Reproductive morphology Fruits
Capsule oblong-clavate, exserted, 2–2.5 mm., the apex spongy-incrassate so that the style is frequently inserted in a definite depression.
Morphology Reproductive morphology Seeds
Seeds 1–1.25 mm., compressed, shining, black, ornamented with a very fine reticulate pattern which is faintest in the almost smooth centre of the seed.
