Peduncle exceeding the leaves, terete, 10-65 cm long, 4-12 mm wide, pale to mid-green. Spathe 11.5-40 cm long; spathe-tube oblong-cylindric, 2-7 cm long, 0.75-2.5 cm wide, moderately to strongly constricted apically, exterior pale to mid green, very rarely mid-brown, sometimes with purple staining along the margin at the top, interior white; spathe-limb linear-lanceolate to lanceolate, 9.5-33 cm long, 2-8 cm wide, erect at first but soon flopping either backwards or forwards and curling apically, margins sometimes crispate, acute to acuminate, externally pale to mid-green, often heavily stained with purple along the margin, sometimes ± entirely purple, rarely entirely green, very rarely mid-brown, internally pale greenish white ± stained with deep purple or maroon, more rarely greenish white with a very narrow purple margin, very rarely mid-brown.

Staminodes in 2 to 4 whorls forming a zone 2-10 mm long; bristles filiform, flexuous, 1.5-9 mm long, violet to deep purple; bases compressed conic, smooth, off-white. Interstices: upper and lower 0-2.5 mm long, usually with numerous rudimentary sterile flower bases, off-white. Staminate flowers in an oblong zone 3-25 mm long, 5-10 mm wide; anthers and connectives deep violet. Pistillodes in 2 or 3 or rarely 4 whorls; bristles filiform, flexuous, 1.5-9 mm long, violet to deep purple; bases compressed conic, smooth, off-white.
