What is "jubaea"

Jubaea is a genus of palms (family Arecaceae) with one species, Jubaea chilensis, or J. spectabilis, the Chilean wine palm or Chile cocopalm. It is native to southwestern South America, where it is endemic to a small area of central Chile, between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins and northern Maule regions. It was long assumed that the extinct palm tree of Easter Island belonged to this genus too, but it is distinct and now placed in its own genus, Paschalococos.
