Discussion

  • Bactris chamleyae is diagnosed by its simple leaves without spines (except for apex of pinnae), densely spinulose peduncle and peduncular bract, and orange fruits with numerous endocarp fibers. There are only two specimens with ripe fruits, but these appear to have endocarp fibers with juice sacs attached. This situation is anomalous, because Sanders (1991) considered that orange-fruited species of Bactris lacked juice sacs attached to the endocarp (but see also B. neomilitaris). Apart from this, B. charnleyae is similar to B. hondurensis. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A
