Lesser Antilles, Barbados, Trinidad and Tobago, northern Venezuela, and northeastern Colombia. Naturalized in Guyana. Surinam, and French Guiana. (Zona, S. 1996. Roystonea.(Arecaceae: Arecoideae). Flora Neotropica Monograph 71, 1-35.)A

Discussion

  • Contrary to reports in the literature (Bailey, 1935, 1949; McCurrach, 1960; Tomlinson, 1961), the leaf segments of R. oleracea are not arrayed in a single plane or "series." The segments are arrayed in two planes on either side of the rachis.
    The leaves of the crown typically do not hang much below the horizontal, unlike other species in which the leaves droop and obscure the crownshaft. This characteristic allows one to identify palms of this species from a distance. Roystonea oleracea is also noteworthy for its unopened peduncular bract which is strongly clavate with an acuminate tip. Groups of rachillae are undulate, forming wavy curves with amplitudes of 4 cm or more (Zona, S. 1996. Roystonea.(Arecaceae: Arecoideae). Flora Neotropica Monograph 71, 1-35.)A
