Discussion

  • Bactris hatschbachii is diagnosed by the bulbousbased spines of its fruits, resembling those on the peduncular bracts of Desmoncus. This species is named for Gert Hatschbach, who collected several of the specimens examined. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A
