INFLORESCENCE with peduncle 27-38 cm long, drying dark yellow brown, many ridged, the ridges sometimes with weak projections; spathe 6.5-9.5 cm long, 0.8-1.5 cm wide, ivory, tinged pink, sometimes green inside, and greenish yellow outside, drying light brown; spadix gradually long-tapered, dark green to brown, 7.5-9.8 cm long, drying 5-6 mm diam. at base.
