INFLORESCENCE spreading; peduncle (9-)13-28 cm x?2-6 mm, usually shorter than petiole; spathe green, lanceolate, spreading, 8.5-12.0 x 1.5-1.8 cm, apex long-acuminate, base cordate; spadix sessile, green (tinged red), cylindric to weakly tapered, (4.0-)6.5-17.0 cm long, 4-8 mm diam. at base, 3-5 mm diam. at apex; 4-6 flowers per principal spiral, 4-lobed, ca. 2.5 x?2.6 mm, sides weakly sigmoid; tepals matte to semiglossy, lateral tepals ca. 1.4 mm wide, inner margin rounded, outer margin angled; stamens exserted; anthers ca. 0.50 x?0.65 mm, thecae ovate-elliptic, slightly divaricate; pistils weakly emergent; stigma round, ca. 0.6 mm across. INFRUCTESCENCE green, up to 34 cm long, 1.0-1.8 cm diam.; fruits green, roundly elliptic, ca. 5 x 3 mm, apex pointed.
