Discussion

  • There is some variation in indument. Leaves of specimens from Trinidad are the most scaly, ramenlose, and punctate, and the leaves have a dense covering of black scales; specimens from Tobago and the Lesser Antilles are less scaly, ramentose, and punctale, and the leaves have whitish brown scales. It is interesting that three species of Euterpe (E. broadwayi, E. oleracea, and E. precatoria) occur on the small island of Trinidad, and remarkable that E. broadwayi has not been found in Venezuela [although Wessels Boer (1988) believed it may occur there]. This species has an unusual distribution for a palm; two other species, Syagrus amara (Jacquin) Martius and Aiphanes minima (Gaertner) Burret, have somewhat similar distributions.
