INFLORESCENCES 1–2 per axil; peduncle 9.5–22 cm long, 0.8–1.3 cm diam., white to medium green, subterete (obscurely and obtusely angled), coarsely whitish-striate; spathe 15–20 cm long, 1.6–3.5 cm wide at tube; tube maroon outside, dark wine-red or red-violet inside, rarely weakly tinged pink inside; blade cream to white, sometimes tinged pink and weakly reddish outside, glossy inside, weakly glossy outside; spadix cylindrical, 14–18.5 cm long, protruding outward at anthesis; staminate portion white to cream; pistillate flowers pale green maturing to greenish white.
