    Latin Diagnosis - Ab onmibus congeneribus fructu spinis basi bulbosis curvulis, basi albidis apice nigris obtecto abstat.

    Species Description - Stems cespitose and forming large clumps, 2.5-5 m tall, 2.5-5 cm diam., spiny on internodes. Leaves number unknown; leaf spines somewhat clustered, black, terete, to 4 cm long, on lateral surfaces of sheath and petiole, fewer on abaxial surface of rachis; sheath to 40 cm long; ocrea not seen; petiole to 16 cm long; rachis to 1.6 m long; pinnae numerous, irregularly arranged, spreading in more or less the same plane, linear, spinulose along the margins, whitish tomentose and setose abaxially; middle pinnae to 50 x 2 cm. Inflorescences interfoliar; peduncle to 20 cm long, recurved, sparsely spiny; prophyll 15-17 cm long; peduncular bract 25-30 cm long, densely covered with appressed, black spines to 1 cm long; rachis 2 cm long; rachillae ca. 14, to 8 cm long; triads irregularly arranged among paired or solitary staminate flowers; staminate flowers not seen; pistillate flowers to 6 mm long; calyx cupular, 3 mm long; corolla tubular, 6 mm long, spinulose; staminodes 6, linear, or absent; fruits ca. 2 cm diam., depressed-globose, purple-black, densely covered with 1.5 mm long, curved, bulbous-based spines, these whitish at the base and black at the tip; mesocarp not seen; endocarp depressed-globose, the sterile pores slightly displaced longitudinally; fruiting perianth with minute calyx and spinulose, lobed corolla, without staminodial ring.

  • Discussion

    Bactris hatschbachii is diagnosed by the bulbous-based 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.
