SUMMARY
Terrestrial; stem to 1 m long; internodes short, to 8 cm long, to 2 cm diam., about as long as broad or sometimes broader than long, dense; roots drying 2--3 mm diam., dark reddish brown, folded into irregular longitudinal ribs; cataphylls fleshy, sharply 2-ribbed, reddish, drying pale yellowish brown to brown, persisting semi-intact as a reticulum of fibers which are persistent; LEAVES: petioles 44--51 cm long, 3--6 mm diam., subterete, obtusely flattened near base adaxially, often purple at apex, surface inconspicuously short-lineate to striate, prominently so towards apex, with moderately dense, hair-like scales, at least near apex, scales many times longer than wide; geniculum darker than petiole; blades ovate-cordate, subcoriaceous, bicolorous, abruptly acuminate at apex (the acumen sometimes apiculate, 2--4 mm long), cordate at base, 34--47 cm long, 1.2--1.4 cm wide (1.2--1.4 times longer than wide), (0.6--0.8 times the petiole length), upper surface semiglossy, lower surface glossy, paler; anterior lobe 24--36 cm long, 11--28(38) cm wide, (0.9--1 times longer than wide), (1.9--2.7 times longer than posterior lobes); posterior lobes 11--14.5 cm long, broadly rounded to obtuse; sinus spathulate or V-shaped; midrib flat to convex, paler than surface above; basal veins 5--7 per side, with 1--2 free to base, 2--3 coalesced (0.7)1--2.2 cm; posterior rib not naked, to 1.5 cm; primary lateral veins 2--4 per side, departing midrib at a 50--65º angle, sunken, raised below; minor veins arising from both the midrib and primary lateral veins; tertiary veins moderately distinct, darker than surface below. INFLORESCENCES 1--2 per axil; peduncle 9 cm long, 6 mm diam.; spathe smooth, 12--13 cm long, (1.5--2.6 times longer than peduncle); spathe blade pinkish white outside; spathe tube magenta outside; spadix to 12 cm long, remaining in the spathe at anthesis; pistillate portion to 2 cm long, 10 mm diam.; staminate portion to 10 cm long; fertile staminate portion gradually tapered to apex, 10 mm diam. at constriction, scarcely constricted above the sterile staminate portion, narrowly rounded at apex, 11 mm diam. near the middle, 10 mm diam. at constriction; pistils 2 mm long, 1.9 mm diam.; ovary (5)6(7)-locular, locules 1.3 mm long, 0.6 mm diam., with axile placentation; ovules ca. 10 per locule, 2-seriate, 0.5 mm long, longer than funicle; funicle 0.3 mm long, adnate to lower part of partition; style similar to style type D; style apex somewhat rounded to flat; the androecium truncate, margins irregularly 4--5-sided, ca. 0.9 mm long. JUVENILE plants with lower blade surface purplish.
