Atlantic Coastal Forest of Brazil (Alagoas, Bahia, Espírito Santo, Pernambuco), lowland rain forest, at 30-200 m elevation.


  • 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.


  • Stems rarely solitary, usually cespitose, 1-3 in tall, 0.5-1.5 cm diam., not spiny on internodes. Leaves 6-10; leaf spines scattered, brown or black, to 1.5 cm long, few on sheath and petiole, mostly absent from rachis; sheath 10-17 cm long, fibrous; ocrea to 3 cm long; petiole 8-25 cm long; rachis 18-50 cm long; pinnae 4-9 per side (or occasionally blade simple or mostly simple), irregularly arranged, spreading in the same or different planes, sigmoid, with fine spinules along the margins, slightly to densely pilose abaxially; middle pinnae 15-30 x 2.5-6.5 cm. 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 x 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.
