General Description
Low-growing herb. Stem short, prostrate, 2 cm in diameter, internodes ca. 1.5 cm long, leafy towards the apex. Cataphyll green, small, 12 cm long, soon drying dark brownish, and slowly breaking up, remains persistent between basal leaves. LEAVES: Petiole rigid, subterete, ventrally flat or semiterete upwards, 2 times longer than the blade, up to 72-92 cm long, and 0.7-0.8 cm thick, glossy, olive-coloured (glossy and straw-yellow when dry); geniculum 0.5-0.8 cm long, wine-coloured. Leaf blade reflexed, papery, more or less brittle, triangular-ovate in outline, deeply cordate or subsagittate at the base, posterior lobes rounded, separated by an oblong-parabolic sinus which is 11-15 cm long, acuminate at the apex (up to 4 cm), 33-48 cm long and 20-24 cm wide (at the extreme base); Adaxially: glossy deep green, midrib sulcate, 0.2 cm wide, primary lateral veins sunken, 4-5 on each side, emerging at an angle of 50º-70º, arcuate, with one secondary vein between each pair, minor veins very fine, 6-7 primary veins in each posterior lobe, joined together at the base in a short posterior rib, barely denuded in the sinus; Abaxially pale green, midrib moderately convex, and principal veins raised, green. New leaves at the time of spreading out are pink. INFLORESCENCE: Peduncle solitary, 10 cm long and 0.7 cm thick, pale brown or from bronze to olive, appearing erect, but curving abruptly upwards (90º), in florescence remaining perpendicular. Spathe 7.7 cm long, tube inflated ellipsoid, 4 cm long and 2.3 cm in diameter (in fruit), rusty red externally or bronze-green, red-wine-coloured below, blade (unopened) slender conical, 1 cm thick, pink-olive green.
