features
Euterpe broadwayi is a multi-stemmed palm with usually two or three stems, more rarely it is single-stemmed. The trunks are gray, upright to slightly leaning, 8 to 20 m high with a diameter of 20 to 25 cm. At the base they have a cone of adventitious roots that can be up to 2 m long.
The crown consists of 10 to 16 leaves . The leaf sheath is 1.3 to 1.8 m long and green to reddish brown. The petiole is 0.7 to 1.2 m long and densely to slightly covered with flat, black, reddish-brown or whitish-brown scales. The rachis is 2.9 to 3.6 m long and covered with similar scales. On each side of the rachis there are 80 to 92 leaflets, which are pendulous to horizontal, but pendulous at the tip. They are leathery, have a distinct midrib and two lateral veins each. The basal leaflet is 70 to 80 cm long, the middle 80 to 120 cm, and that at the tip 30 to 50 cm.
The inflorescences arise between the leaves and stand horizontally at flowering time. The inflorescence stalk is 15 to 20 cm long and around 3 cm thick. The cover sheet is around 1.3 m long, the bract on the inflorescence stalk around 1.2 m. The inflorescence axis is around 45 cm long, there are around 95 side axes that are 70 to 95 cm long. The latter are densely covered with 1 to 2 mm long, branched, whitish-brown hairs. The flowers stand in triads on around two thirds of the axial length, in the distal area male flowers are paired or single.
The male flowers are up to 5 mm long. The sepals are broadly oval, 3 mm long and membranous. The petals are oval, 3.5 to 4 mm long and fleshy. The stamens stand on a short receptaculum. The stamens are 1.5 mm long and flattened, the anthers are 2.5 mm long. The rudiment of the stamp is 1.5 to 3 mm long and deeply three-lobed at the tip. The female flowers are up to 4 mm long. Sepals and petals are broadly oval and up to 4 mm long.
The fruits are spherical to slightly compressed with a diameter of 1 to 1.4 cm. The scar remnant is subapical to the side. The exocarp is purple-black and finely bumpy. The seeds are spherical, the endosperm homogeneous and the primary leaf is pinnate.
