INFLORESCENCES 1-2 per axil; peduncle cylindrical, 8-10 cm long, ca. 6 mm diam., white, with long white coarse striations at apex; spathe 16-17 cm long, white, tinged red on tube (at least on the abaxial surface) outside, minutely pale-speckled; blade white on both surfaces; spathe tube red within, often also tinged red on lower 2/3 of blade; spadix 14 cm long; fertile staminate portion 8.5 cm long, 1 cm diam in the broadest part; sterile staminate portion 2 cm, 1.2 cm diam; pistillate portion 4 cm long, 1 cm diam. INFRUCTESCENCE not seen.
