Description
Bactris oligocarpa is a small shrub[1] or palm tree, that grows 0.2–1.5 metres (0.66–4.92 ft) high. The stems are usually solitary, and 0.8–1 centimetre (0.31–0.39 in) wide.[3] The plant has black prickles, which are up to 3 centimetres (1.2 in) long.[4]
The plant has four to fifteen compound leaves, with segments in two to seven pairs.[3][4] The leaves have 22–50 centimetres (8.7–19.7 in) stems.[3] The flowers grow on 6–13 centimetres (2.4–5.1 in) stems, which lack spines. The male flowers are 5–6 millimetres (0.20–0.24 in) long, and have six stamens. The lobes of the sepals are around 2 millimetres (0.079 in) long. The petals are 5–6 millimetres (0.20–0.24 in) long. The calyx is tubular, and up to 3 millimetres (0.12 in) long.[3]
The fruits are ovoid, 1.7–2 centimetres (0.67–0.79 in) long, 1–1.5 centimetres (0.39–0.59 in) wide, black to purple,[3] and have a smooth outer layer.[4] The mesocarp is juicy, and the endocarp is ellipsoid.[3]
