Discussion

  • Bactris caryotifolia is diagnosed by its wedge shaped, distally praemorse pinnae. The type specimen is somewhat problematic. A specimen at M (F neg. 18607) bears a label saying that it was collected by Poeppig in Peru, but because this species does not occur in Peru, this must be a mistake. Handwriting on the label indicates that Martius saw this specimen, and it may be the Beyrich specimen that he used to describe the species. I have decided, however, to designate a neotype in view of this doubt. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A
