Pacific slope of Central America in Nicaragua (Chontales, Granada), Costa Rica (Guanacaste, Puntarenas), Panama (Coclé, Los Santos, Panamá), northern Colombia (Atlántico, Bolívar, Córdoba, La Guajira, Magdalena, Sucre), and Venezuela (Bolívar, Cojedes, Guárico, Monagas, Portuguesa, Zulia).

  • Open, often disturbed places, and deciduous forest, often near the coast, in areas that experience prolonged dry seasons, I0-400 m elevation. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A


  • Baetris guineensis is diagnosed by its linear, pale gray-green pinnae that are asymmetrically and briefly bifid at the apex and readily fall from dried specimens. Synonymy was established by de Nevers et al. (1996). Glassman (1972) and Henderson et al. (1995) included Aiphanes minima (Gaertner) Burret in synonymy here but it does not belong.
