flooded soils mainland Amazonian forest (250–1,000 m). The species is less common in Amazon terra firme forest. Found in the Ecuadorian provinces of Morona-Santiago, Napo, Orellana and Sucumbios. The species is common in the Parque Nacional Yasuní and the Reserva de Producción Faunística Cuyabeno. It probably also occurs in the Limoncocha and Sumaco-Napo-Galeras protected areas.

Comments and Curiosities

An understorey palm endemic to Ecuador, where it is widely distributed in the Amazon rainforest and common in the Parque Nacional Yasuní and the Reserva de Producción Faunística Cuyabeno. The species probably also occurs in the Limoncocha and Sumaco-Napo-Galeras protected areas. The species prefers habitats with poorly drained or seasonally flooded soils and is less common in Amazon terra firme forest. Because of its asexual reproduction, it is common to find two or three clones growing together. Many authors consider A. urostachys to be a variety of A. murumuru Mart. Apart from habitat destruction, no specific threats are known. (IUCN)
