    General Description
    Based on dried material only. Terrestrial; stem short. 1.8-2.5 cm diam.: roots moderatelv numerous, grayish brown, puberulent, slender, elongate, 2-3 mm diam.; cataphylls 9.5-20 cm long, acuminate to short-acuminate at apex, light brown, persisting semi-intact as fine linear fibers. LEAVES: petioles 8-15 cm long, 5-8 mm diam., D-shaped to subtriangular, broadly rounded to sulcate adaxially, the margins thin, prominently raised, appearing winged, rounded and acutely to obtusely 1 -ribbed abaxially; geniculum slightly thicker than petiole, (0.5)1.5-2 cm long; blades coriaceous, narrowly to broadly oblong-elliptic, acute, sometimes shortly acuminate at apex, acute to narrowly acute (rarely rounded) at base, 40-94 cm long, 6-12 cm wide, broadest at or near the middle, the margins narrowly undulate; upper surface green, slightly paler below, both surfaces matte to semiglossy, yellowish brown, sometimes greenish; midrib convexly raised above, prominently raised and 1-ribbed at base, becoming narrowly acutely raised toward the apex below; primary lateral veins darker than surface, 25-35 per side, departing midrib at 30-55° angle, straight to weakly arcuate to the collective vein, prominently raised above; interprimary veins numerous, almost as conspicuous as primary lateral veins; tertiary veins prominulous; collective vein arising from the base, raised above and below, equally as prominent as primary lateral veins, 5- 10 mm from margin. INFLORESCENCES apparently spreading; peduncle 15-55 cm long, 5-8 mm diam., 2.2 -3.1 x as long as petioles, green, sharply angular, rarely terete; spathe erect to reflexed, subcoriaceous, yellowish green, lanceolate to ovatelanceolate, 5-9 cm long, 1- 1.3 cm wide, acuminate at apex (the acumen inrolled), narrowly acute at base; spadix dark purple, cylindroid, subsessile, 6-12 cm long, 5-12 mm diam.; flowers rhombic, 1.9-2.4 mm long, 1.5-2.1 mm wide, 4-6 flowers visible in principal spiral, 9-1 2 in alternate spiral; tepals minutely papillate, lateral tepals 1.4-2 mm wide, the inner margins straight, sometimes broadly convex, occasionally turned up against the pistil, the outer margins 2-sided; pistils slightly raised; stigma slitlike, 0.5-0.7 mm long; filaments prominently exserted, holding anthers above tepals, the exserted part 0.5-0.7 mm long; anthers yellow, 0.4-0.5 mm long, 0.5 mm wide; thecae oblong-ovoid, not divaricate. INFRUCTESCENCE with spathe persisting; spadix ca. 15 cm long, 1 cm diam.; berries drying 2.5-4 mm diam., probably orange.
    Anthurium angustilaminatum is comprised of two subspecies, the typical one known only from the slopes north of Volcán Pichincha in Pichincha Province in northern Ecuador, and subsp. cibuserpentis , from Cotopaxi and El Oro further to the south.
