Morphology General Habit
Shrub or liane 1.3–20 m. tall; young branches sparsely setose; older branches with fawn-coloured bark.
Morphology Leaves
Leaf-blades drying brownish, elliptic to broadly elliptic, 4–7.5 cm. long, 2.4–4 cm. wide, obtuse to subacuminate and often shortly apiculate at apex or sometimes emarginate, obtuse or rounded at base, subcoriaceous, moderately shiny above, sparsely setose on midrib beneath; lateral nerves in 6 main pairs, impressed above; tertiary nerves moderately finely reticulate, rather obscure; domatia present as tufts of brown or rusty coloured hairs; petioles 4–10 mm. long, densely setose; stipules lanceolate, 4–8 mm. long, setose, caducous.
Morphology Reproductive morphology Flowers
Flowers 5–6-merous, borne in pedunculate, 1–20-flowered cymes; peduncles 0.5–2.5 cm. long, sparsely setose; pedicels 3–6 mm. long, sparsely setose; bracteoles inconspicuous, lanceolate.
Morphology Reproductive morphology Flowers Calyx
Calyx-tube ellipsoid, 2.5 mm. long, glabrous; calyx-limb well developed, 1.75–2 mm. long, divided almost to base into 5–6 triangular lobes, sparsely setose outside, coarsely reddish setose inside.
Morphology Reproductive morphology Flowers Corolla
Corolla yellowish green (only known from mature bud); tube 7 mm. long, with a ring of deflexed hairs at mid-point, pubescent above and below; lobes narrowly oblong, 4 mm. long, 1.75 mm. wide.
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigmatic knob ± 2 mm. long.
Morphology Reproductive morphology Flowers Disc
Disk glabrous.
Morphology Reproductive morphology Fruits
