Stipe of spadix to ca. 1.0 cm long, adnate to spathe; spadix 11.8-17.1 cm long, the fertile male portion 0.6-0,9 cm wide, white; sterile male zone 0.6-1.0 cm long; female portion of spadix 4.5-7.2 cm long, F/S=0.33-0.45, (0,8-) 1.0-1.1 cm wide, pale green; fertile male flowers 0.8-2.0 mm long, 0.7-1.3 mm wide, irregularly polygonal, often butterfly-shaped, columnar and ridged; sterile male flowers 0.8-1.5 mm long, 0.8-1.7 mm wide, anvil-shaped, substipitate; female flowers 1.6-2.2 (-2.7) mm long, 0.5-0.7 (-1.1) mm wide, the stylar canals 4 (-5?).
