Mostly south of the Amazon river in Colombia (Amazonas), Peru (Huanuco, Loreto, San Martin, Ucayali), and western Brazil (Acre, Amazonas); lowland rain forest either on terra firme or more commonly in areas liable to seasonal inundation or other wet places, at 106-600 m elevation (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A

Discussion

  • Bactris bifida is diagnosed by its long, narrow, simple, strongly plicate leaves, deeply bifid apically and cuneate basally, staminodial ring, and ellipsoid, purple-black fruits. Synonymy was established by Henderson (1995), although he (and Henderson et aI., 1995) included B. angustifolia as a synonym of B. tomentosa var. sphaerocarpa, it properly belongs here.
    There is considerable variation in the size of the leaves; specimens from the Andean foothills of Peru have much larger leaves than usual (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A

Common Name
