This species is a robust, high‑climbing, evergreen woody vine known for its strong, twisting stems and lush foliage. Mature vines develop woody main stems up to 200 mm in diameter, with grey‑brown, furrowed bark. Upper stems are more flexible, stout and almost hairless.

Leaves:

• Dark green and smooth on the upper surface
• Pale green with sparse white hairs underneath
• Three‑foliolate, typically 70–130 × 60–120 mm
• Leaflets are thick (coriaceous) and broadly ovate to broad‑oblong, with bases ranging from heart‑shaped (cordate) to truncate
• Leaf margins vary from smooth to shallowly toothed or lobed, especially near the apex
• Occasionally, leaves may be deeply lobed or almost dissected
• Petioles are 30–60 mm long

Flowering occurs in compound axillary clusters (dichasial cymes). Flowers are unisexual, with both male and female blooms found on the plant.

Bracts are paired, often united and sometimes leaf‑like, positioned below the middle of the flower stalk.

Male Flowers

• 6 white sepals, overlapping and hairless above but hairy underneath
• Sepals are 25–35 mm long, sometimes reaching 60 mm
• Numerous stamens with anthers 1.5–2.0 mm
• Filaments may be sparsely hairy or smooth

Female Flowers

• Sepals similar in form to male flowers but smaller: 20–25 mm, occasionally up to 40 mm
• Contain a few staminodes

Fruit

• Produces small, hairy achenes (2–4 mm)
• Fruiting style becomes plumose, extending 3.5–6.5 cm
