Distribution

Bactris syagroides is native to the wet tropical biome of northern Brazil (Amazonas and Pará).[1] It grows in lowland rainforests.[3]

Description

Bactris syagroides is a shrub.[1] It grows 0.6–1.5 metres (2.0–4.9 ft) high, and 0.8–2 centimetres (0.31–0.79 in) wide. The stems lack spines, and are covered in decaying leaf bases.[3]

The plant has five to eight leaves, with scattered black spines that grow up to 1 centimetre (0.39 in) long. The leaf stems are 45–90 centimetres (1.48–2.95 ft) long. The leaves are compound, and have thirty to thirty-eight regularly arranged pinnae on each side.[3]

The flower stems are spiny, and up to 4.5 centimetres (1.8 in) long. The male flowers are 3–4 millimetres (0.12–0.16 in) long, and have four to six stamens. The sepal lobes are 0.5–1 millimetre (0.020–0.039 in) long. The female flowers are 2–3 millimetres (0.079–0.118 in) long. The calyx is cup-shaped, and 0.3–1 millimetre (0.012–0.039 in) long. The corolla is tube-shaped, and 2–3 millimetres (0.079–0.118 in) long.[3]

The fruits are round, yellow-orange, and 6–8 millimetres (0.24–0.31 in) in diameter. The mesocarp is starchy. The endocarp is pitted and obovoid.[3]

Etymology

Bactris syagroides is named for its resemblance to Syagrus cocoides.[4]
