  • Description

    Variety 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, 1833 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.

  • Discussion

    The holotype of Bactris hirta subsp, pulchra (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.
