Euterpe longibracteata is a species of palm native to South America.

features

Euterpe longibracteata is a single-stemmed palm, rarely multi-stemmed. The trunk is upright, 5 to 15 (rarely up to 20) m high and 5 to 8 cm in diameter. At the base the trunk has a cone of orange to red adventitious roots that are 0.5 to 1.5 m long.

The crown consists of 8 to 9 leaves . The leaf sheath is 0.8 to 1.5 m long, green with scattered, reddish-brown, woolly scales. The petiole is 19 to 41 cm long, the rachis 2.5 to 3 m. On each side there are 70 to 79 leaflets, which have a distinct midrib and two lateral veins. The basal leaflet is 39 to 45 cm long, the middle 52 to 59 cm, the terminal 14 to 21 cm long.

The inflorescence stands between the leaves, at flowering time it is horizontal. The inflorescence stalk is 6 to 10 cm long. The cover sheet is 45 to 65 cm long, the bract on the inflorescence stalk is 60 to 68 cm long. The inflorescence axis is 11 to 36 cm long, on it sit around 60 side branches 21 to 45 cm in length. The flowers stand in triads almost to the tip of the side branches.

The male flowers are up to 5.5 mm long. The sepals are broadly oval, up to 2 mm long and ciliate. The petals are oval, 5 mm long, the stamens are on a short receptaculum. The rudiment of the stamp is around 2 mm long and deeply three-lobed at the tip. The female flowers are up to 3 m long. The sepals and petals are broadly oval, 2.5 mm long and finely lashed.

The fruits are spherical with a diameter of 1 to 1.2 cm. The remnant of the scar is clearly visible and is to the side. The exocarp is purple-black and finely bumpy. The seeds are spherical, the endosperm homogeneous.

Distribution and locations

The species occurs in Venezuela, Guyana and Brazil. It grows in lowland forests, mostly on terra firme , and more rarely in regularly flooded areas. It occurs sympatric with Euterpe precatoria and in some areas also with Euterpe oleracea .
