Inflorescences interfoliar; peduncle 3-7 cm long, recurved, spinulose; prophyll 8-10 cm long; peduncular bract 7-18 cm long, densely covered with soft, brown or black, appressed spines; rachis 2-3 cm long; rachillae 2-4, 1-4 cm long, at anthesis glabrous; triads irregularly arranged among paired or solitary staminate flowers; staminate flowers 2-3 mm long, open in bud with the stamens visible; sepal lobes to 1 mm long; petals 2-3 mm long; stamens 6; pistillode absent; pistillate flowers to 3 mm long; calyx annular, 0.5 mm long; corolla tubular, to 3 mm long; staminodes 6, small; fruits to 1.8 × 1.2-1.5 cm, obovoid, rostrate, reddish purple; mesocarp starchy; endocarp obovoid, the sterile pores displaced longitudinally; endocarp fibers few; fruiting perianth with small calyx to 1 mm long and irregularly lobed, 3 mm long corolla, without staminodial ring.

  • Discussion

    Bactris pickelii is diagnosed by its staminate flowers open in bud with the stamens visible. The holotype was destroyed and I have not seen the isotype. The original description, and recent collections from near the type locality, leave little doubt as to the application of the name.
