Neuropeltis racemosa is usually found in old secondary forest but rarely in virgin forest. The fruits are generally in green colour, which is similar to the leaf. It is one of the large woody climbers. Young stems are mostly brown tomentose while mature stems are glabrescent.

Petiole 1–1.5 cm; leaf blade elliptic to elliptic-oblong, 6–12 × 2–6.5 cm, leathery, base broadly cuneate to attenuate into petiole, apex acute or short acuminate; lateral veins 7–10 pairs, nearly glabrous.

Inflorescences 1–6 per axil, racemose; axes brown tomentose; bracts ovate to ovate-lanceolate, 2–3 mm, mucronulate, 1 broadly elliptic to circular in fruit, enlarging to 3–4.5 cm, glabrous except along veins.

Sepals unequal, densely pubescent abaxially; outer 2 sepals circular or slightly wider than long, 2–2.5 mm; inner 3 sepals wider than long, 1.75–2 mm.

Corolla white, broadly campanulate, ca. 5 mm, deeply 5-lobed; lobes incurved, longer than tube, pilose outside, apex obtuse. Filaments ca. 3 mm. Ovary ovoid, pubescent; stigma ca. 1 mm wide.

Capsule nearly globose, 5–6 mm in diameter.

This species is widely distributed in Malaysia.
