Mauritiella is a dioecious genus of flowering plant in the palm family found in South America where it is commonly called buriti.

[2][3][4] Four species are recognized:[2] From 7.5 to 18 m tall, the trunks are clustering and armed with small spines, usually with stilt roots at the base.

The round fruit is usually one-seeded and covered in red to brown scales with a thick, fleshy mesocarp.

Mauritiella palms are found throughout South America's northern half on mountains, alongside rivers and watercourses, in rain forest and in cleared or open savanna.

M. aculeata grows on the banks of the Orinoco and its tributaries in Venezuela, Colombia, and Brazil, M. macroclada inhabits the western slopes of the Andes in Colombia and Ecuador to an elevation of 900 m, with M. armata (locally known as aguajillo) being the most widespread, found throughout Amazonia and adjacent uplands, alongside streams and rivers.
