General Description
Epipetric; stem short; roots thick, tan, sometimes directed upward; cataphylls ca. 7 cm long, drying brown, persistent, weathering to coarse linear fibers. LEAVES spreading; petioles 16-50 cm long, 6-9 mm diam., broadly and sharply sulcate, weakly glaucous; geniculum 1.3-1.5 cm long; blades oblong to lanceolate, subcoriaceous, acute at apex, truncate at base, 27-64 cm long, 6.5-12 cm wide; both surfaces matte and glaucous, the lower surface only slightly paler; midrib convexly raised above, diminished and sunken at apex, more acutely raised below; basal veins one pair, sunken above, raised below; primary lateral veins 6-10 per side, departing midrib at 40° angle, sunken above, raised below; interprimary veins weakly sunken above, flat below; lesser veins obscure; collective vein arising from the basal vein, 8-10 mm from margin, sunken above, raised below. INFLORESCENCE spreading, shorter to as long as leaves; peduncle 31-52 cm long, subterete, 1-2 faint ribs; spathe subcoriaceous, green (B & K Green 5/7.5), lanceolate, 3.5-7 cm long, 1-2 cm wide, long-acuminate at apex, clasping at base, inserted at 180° angle on peduncle; spadix sessile, green (B & K Yellow-green 7/7.5) becoming pale yellow, 3.5-9 cm long, 7-10 mm diam. at base, 3-5 mm diam. at apex; flowers 4-lobed, ca. 2.3 mm in both directions, the sides jaggedly sigmoid; 5-7 flowers visible in the principal spiral, 7-9 flowers visible in the alternate spiral; tepals matte, lateral tepals ca. 1 mm wide, the inner margin convex; pistils green, weakly emergent; stigma slit-like; stamens emerging from the base, laterals emerging first, followed quickly by alternates, the leading stamen preceding fourth stamen by 1-3 spirals. INFRUCTESCENCE pendent, mature berries not seen.
Habitat
