General Description
Epiphyte; stems green, less than 10 cm long, 1 cm diam.; leaf scars moderately conspicuous, ca. 5 mm wide; roots spreading, short, green to purplish brown in age; cataphylls thin, 2-2.5 cm long, acuminate at apex, drying tan, weathering and persisting more or less intact, deciduous at lower nodes. LEAVES spreading; petioles terete, 11-20 cm long, 2-3 mm diam.; geniculum 1-1.5 cm long, scarcely thicker or paler than petioles; blades lanceolate, subcoriaceous, gradually to abruptly acuminate at apex (the acumen apiculate), obtuse to subrounded at base, 9-17 cm long, 2.7-6.3 cm wide, usually broadest in the lower third: both surfaces semiglossy, the upper surface eglandular, the epidermal cells convex, the lower surface dark glandular-punctate; midrib raised at base above, sunken at apex, raised below; primary lateral veins 4-5 per side, departing midrib at ca. 45° angle, straight to collective vein, scarcely sunken above, prominulous below, lesser veins scarcely visible above and below: collective vein arising from the base, 4-6 mm from margin. INFLORESCENCE spreading, as long as or longer than leaves; peduncle terete. 15-28 cm long, 1.5-2.5 mm diam., equalling or up to one and a half times longer than petioles: spathe moderately thin, medium green, lanceolate, 3-3.5 cm long, 7-8 mm wide, broadest just above base, acuminate at apex, rounded at base, the margins turned up, inserted at 90° angle on peduncle; stipe ca. 3 mm long in front, ca- 2 mm long in back, ca. 2.5 mm diam.; spadix olive green (B & K Yellow-green 5/5-5/7.5), sometimes becoming tinged with violet purple, 4-7.5 cm long, 4.5-5 mm near base, tapered to less than 1 mm at apex; the flowers square, 4-4.7 mm in both directions, the sides straight parallel to the spirals, weakly sigmoid perpendicular to the spirals, 2-3 flowers visible in the principal spiral, 5-6 flowers visible in the alternate spiral; tepals semiglossy, lateral tepals 2.7-3.2 mm wide, the inner margin more or less straight; pistils emergent, weakly raised, green; stigmas slit-like with minute exserted papillae; stamens emerging promptly from base, laterals emerging first at least to middle before alternates emerge, retracting promptly, usually with no more than one stamen visible per flower at any time; anthers pale green, ca. 0.5 mm long, ca. 1 mm wide; thecae broadly ovoid, widely divaricate; pollen white. INFRUCTESCENCE to 11 cm long; berries orange, depressed-globose, ca. 4 mm long, 5 mm diam.; seeds usually 4, 2-2.5 mm long, 1-1.2 mm diam., weakly flattened.
