SUMMARY
Epiphyte; STEM internodes short, 1.5 cm diam.; roots gray to whitish, to 16 cm long, 5-8 mm diam.; cataphylls 6-10.5 cm long, turning reddish brown, persisting intact, erect. LEAVES with petioles 6.5-10.5 cm long, 4-6 mm diam, sharply and deeply sulcate, subcoriaceous, dark green and matte above, slightly paler and matte below, sheathing (0.37-)0.52-0.60 (averaging 0.53) its length; sheath 4.0-6.5 cm long, the margins pale green; blades oblong-elliptic to narrowly ovate-elliptic, 25-30 cm long, 3-5 cm wide; midrib prominently raised, weakly paler and acute to bluntly acute above, bluntly acute and paler below with an acute medial rib toward the base; primary lateral veins obscure on both surfaces, ca. 15-20 per side, scarcely or not at all raised, concolorous; collective veins moderately obscure, arising from the base, irregular, 3-6 mm from margin; minor veins obscure. INFLORESCENCE stiffly erect at anthesis; peduncle 18-30 cm long (averaging 28.7 cm), 3.5-4 mm diam., medium green, semiglossy, sometimes acutely angular with several smaller ribs on either side near the apex; spathe medium green, weakly glossy inside, slightly glossier outside, 8.5-13 cm long, 1.2-2.0 cm wide, the margins turned under and sometimes tinged violet-purple, narrowly long-acuminate at apex with only the midvein clearly visible, subcordate and clasping peduncle at base; spadix 10.5-14 cm long, (3-)4-7 mm diam., sessile, straight, pale yellow to yellowish green or brownish yellow green, semiglossy; flowers 3-4 visible per spiral, 5-7(-9) mm long, 4-6 mm wide, prominently 4-lobed; tepals shield-shaped, 3.1-3.5 mm wide, the inner margin broadly rounded, outer margin 4-sided, both the sides parallel and perpendicular to the spiral, jaggedly sigmoid; pistils 1.3-1.5 mm long, 0.85-0.90 wide; stamens barely emergent, positioned at the margin of the tepals at anthesis, yellowish, 0.75 mm long and wide pre-anthesis, becoming 0.5 mm long and 0.75 mm post-anthesis with the thecae broadly divaricate; pollen golden-yellow. INFRUCTESCENCE spreading-pendent, peduncle 25-33 cm long, the spadix portion to about 19 cm long, 9 mm diam. before berries emerge, to 2.5 cm diam when berries emerge; berries orange-red, subglobose to broadly obovoid, 8-10 mm long, frequently broader in the direction of the axis, 7-9 by 8-9 mm wide., the apex not markedly depressed medially, often marked with cross-like ridges oriented at ca. 45 degrees with the axis; seeds medium yellowish green but darker yellow-green on one end, 3.6-3.8 mm long, 2 mm wide, 1.7 mm thick, bearing a transparent, stick appendage on the chalazal end of the seed, sometimes also with a smaller appendage on the opposite end of the seed.
