Vaginal leaves 5–7, purple-red, up to 10 cm long, enveloping base of petiole, becoming black-brown when dry. Leaves solitary, 1–2 cm apart; petiole stiff, upright, 22–54 cm long, 2–3 mm thick, adaxially sulcate; leaf blade usually narrowly elliptic to oblong-lanceolate, 28–38 cm long, 6–8 cm wide, dark green with small yellow-white spots on both surfaces, base cuneate to narrowly cuneate, gradually narrowing into petiole, inequilateral, apex acuminate, margin serrulate, with prominent midvein and 3–4 inconspicuous secondary veins on lower surface. Peduncle erect or declining, purple, 2–5 cm long, with 5–7 bracts, bracts gradually wider from base to top of peduncle, the distal ones at base of perigone broadly ovate, purplish red to dark purple, 12–15 mm long, 10–14 mm wide, apex subobtuse. Flower solitary, with light pleasant fragrance; perigone urceolate, fleshy, externally greenish white and with purplish red spots or completely blackish purple, 14−16 mm tall,6 lobed apically; lobes usually suberect, sometimes slightly recurved, subequal, triangular, 6–8 mm long, 4.5–7 mm wide at base, internally purplish red mottled to completely purplish red, densely verruculose and thickened at base; tube 9–10 mm long, greatest diameter 18–20 mm, the opening 5–6 mm in diam., adaxially blackish purple and shallowly verruculose at the upper part of the perigone tube, white at the bottom half of the tube. Stamens 6, opposite to lobes, inserted in the middle of the perianth tube, positioned lower than stigma; filaments horizontal, 1–2 mm long, anthers oblong, yellow, 2–3 mm long and ca. 2 mm wide. Pistil 6–7 mm long, ovary slightly swollen, style greenish white or white with purple mottling, cylindrical, ca. 5 mm long and 2 mm in diam., stigma discoid-peltate, fleshy, 10–12 mm in diam., 3-lobed, each lobe distally emarginate, upper surface nearly flat, densely verruculose, dark purplish red, with 3-radial, bifurcate, whitish shallow groove marks, lower surface blackish purple, slightly verrucose.
