Distribution

Colombia (Amazonas) and Peru (Loreto) and Brazil (Amazonas) lowland rain forest on terra firme at 122-140 m elevation. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A

Discussion

  • The holotype of Bactris hirta subsp. pulehra (J .Trail 876/XCVIII) is problematic, because it has the short petiole and bifid blade typical of var. hirta, but a spiny sheath and petiole, typical of var. spruceana. Although it is thus somewhat intermediate, I choose to place it here. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A

Description

  • Sheath and petiole densely brown-spinulose or-tomentose, leaf spines absent (rarely present); petiole 4-12(-29) cm long; rachis 12- 16 cm long; blade simple, narrow to broadly obovate, deeply bifid, 18-33 cm long, 9-17 cm wide at apex of rachis, often spinulose marginally, abaxially and sometimes adaxially,with prominent cross-veins, lighter green abaxially. Fruits spinulose. (Henderson, A.J., Bactris (Palmae) in Flora Neotropica Monographs 79. 2000)A
