Distribution and habitat. Nicaragua (Río San Juan, Zelaya), Costa Rica (Alajuela, Cartago, Heredia), and Panama (Bocas del Toro); lowland rain forest at 5-700 m elevation. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A


  • Bactris caudata is diagnosed by its glaucous, linear to ovate, concave pinnae with spinules 1-3 mm long on the margins, 1.5-2 cm long inflorescence rachis, 5-10 cm long rachillae, and orange fruits without endocarp fibers. Synonymy was established by de Nevers et al. (1996).
    A few specimens, (Costa Rica. Heredia: Finca La Selva, RIO Puerto Viejo just E of its jct. with Rio Sarapiquí, ca.100 m, 30 Aug 1980, Hammel 9632 (DUKE); 29 June 1995, Mowbray & Wilbur 1583 (DUKE); 15 Jul 1995, Mowbray & Wilbur 1702 (DUKE); Zona Protectora, between Rio Guacimo and Rio Peje, ca. 250-400 m, 23 Jul 1984, Jacobs & Grayum 2959 (DUKE) resemble Bactris caudata but have larger fruits (1.5-2 cm diameter) and these have endocarp fibers with juice sacs attached. These specimens have been annotated as hybrids between B. caudata and B. coloradonis. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A
