Peru present (World Checklist of Arecaceae)B
Known only from the type locality in Peru (Pasco); understory of moist cloud forest bordering pajonal vegetation, characterized by its shrubby, xeromorphic composition, at 2000-2500 m. (Gloria Galeano & A. Henderson: Flora Neotropica, Monograph 72)A


  • This unusual species not only has a very narrow range (as currenlly known) but it also is unique in having ellipsoid fruits, a condition nearly unknown in both Prestoea (rarely occurring in P. acuminata var. dasystachys) and Euterpe. It is also unusual in the genus in having a pinnate eophyll with an elongate rachis, and staminodes in the pistillate flowers; both of these characters occur in Prestoea. (Gloria Galeano & A. Henderson: Flora Neotropica, Monograph 72)A

Use Record

  • Euterpe luminosa A.J.Hend., Galeano & Meza: El 59% de las especies (13 spp.) reportaron el uso alimenticio tanto de frutos, como de semillas, palmito u otros derivados de estos; cinco de estas especies son utilizadas exclusivamente para este fin, Allagoptera leucocalyx, Bactris hirta y B. major son buscadas solamente por sus frutos, mientras que Dictyocaryum lamarckianum y Euterpe luminosa son extraidas ocasionalmente por el palmito.
