Bactris cuspidata is native to the wet tropical biome of northern Brazil, French Guiana, and Suriname. It grows in lowland rainforests at elevations of 250–780 metres (820–2,560 ft).

Description

Bactris cuspidata is a shrub. The stems are 1–1.5 metres (3.3–4.9 ft) tall, and 6–8 millimetres (0.24–0.31 in) wide.

The plant has four or five leaves, which have scattered black spines that are up to 2 centimetres (0.79 in) long. The leaves have six to thirteen irregularly clustered pinnae on each side. The leaf stems are 35–40 centimetres (14–16 in) long.

The inflorescence stem is curved, spiny, and 4–6 centimetres (1.6–2.4 in) long. The male flowers are up to 3 millimetres (0.12 in) long, and have sepal lobes that are up to 0.5 millimetres (0.020 in) long. The male flowers have five stamens. The female flowers are 2–3.5 millimetres (0.079–0.138 in) long, and have a 0.2–1 millimetre (0.0079–0.0394 in) long calyx and a spiny, tube-shaped, 2–3.5 millimetres (0.079–0.138 in) long corolla.

The fruits are globose to obovoid, 6–7 millimetres (0.24–0.28 in) long, and orange-red. The mesocarp is starchy, and the endocarp is turbinate.
