A large spreading shrub usually 2.5–3.5m tall. The sweetly perfumed flowers are funnel-shaped, bright yellow or peach coloured, 5.5–7cm long and 2.5–4cm wide, grouped in clusters at the end of the branches. The leaves are glossy green, strap-like, alternating on the stem, 5.5–15cm long and 0.5–1.5cm wide. The fruit are angular, green when immature, ripening black, broader than long and somewhat triangular in outline, with a raised ridge around the middle, about 3–4.5cm in diameter. The fruit is fleshy and soft like a plum and encloses a “stone” comprising two starchy kernels.
