Discussion

  • Bactris plumeriana is diagnosed by its linear, 46-67 pinnae per side, and depressed-globose, red, fruits 1.3-1.5 cm diameter. Salzman & Judd (1995) have given a detailed description and discussion of relationships of this species. Bactris ? chaetophylla, listed as an ambiguous name by Salzman & Judd, is a synonym of B. plumeriana. The type and description are based on a juvenile leaf.
