Panamápresent (World Checklist of Arecaceae)C
Eastern Panama (Coclé, San Blas); lowland and premontane rain forest on steep slopes at 0-1000 m. (Gloria Galeano & A. Henderson, Flora Neotropica Monograph 72)B

This variety is otherwise known only from Panama, while Colombian plants belong to var. pubens (Borchsenius F., Borgtoft-Pedersen H. and Baslev H. 1998. Manual to the Palms of Ecuador. AAU Reports 37. Department of Systematic Botany, University of Aarhus, Denmark in collaboration with Pontificia Universidad Catalica del Ecuador)A

Discussion

  • Prestoea pubens var. pubens differs in that the inflorescence is once branched with 3-10 branches and the endosperm is deeply ruminate. Fruits of Ecuadorian plants have not yet been collected and the taxonomic position of these thus remains slightly uncertain. (Borchsenius F., Borgtoft-Pedersen H. and Baslev H. 1998. Manual to the Palms of Ecuador. AAU Reports 37. Department of Systematic Botany, University of Aarhus, Denmark in collaboration with Pontificia Universidad Catalica del Ecuador)A

Common Name

  • Panama: siler burwi (Kuna). (Gloria Galeano & A. Henderson, Flora Neotropica Monograph 72)B

Description

  • Inflorescence unbranched or more rarely once branched with up to 4 branches. Fruits with scarcely ruminate endosperm. (Borchsenius F., Borgtoft-Pedersen H. and Baslev H. 1998. Manual to the Palms of Ecuador. AAU Reports 37. Department of Systematic Botany, University of Aarhus, Denmark in collaboration with Pontificia Universidad Catalica del Ecuador)A
  • Inflorescences spicate or branched; rachillae 1(-4), glabrous or rarely with simple to furcate, substellate or stellate, 0.1 mm long, white hairs; staminale flowers 2.5-4 mm long; petals usually glabrous; fruits with endosperm lightly (almost homogeneous) ruminate.
