Anthurium vallense

Creeping epiphyte or terrestrial; stems elongate, to 60 cm long or more, ca. 1.5 cm diam.; internodes to 1.5 cm long, shorter near apex; leaf scars ca. 1 cm wide; roots long, thin, moderately dense; cataphylls 12-14 cm long, green, acute and apiculate at apex, drying tan, weathering to reticulate fibers and persisting. LEAVES spreading; petioles 7-19 cm long, 1-1.5 cm wide, triangular, sharply sulcate, sharply 1-ribbed abaxially; geniculum 1-3 cm long, shaped like petiole; blades elliptic to oblanceolate-elliptic, coriaceous, abruptly short to long acuminate at apex (the acumen minutely apiculate), acute to obtuse at base, 17-40 cm long, 5-16 cm wide, broadest near middle or above; both surfaces glossy, the upper surface minutely glandular-punctate; lower surface minutely and more or less densely glandular-punctate; midrib raised above, narrowly acute, diminishing toward apex, sharply and acutely raised below; primary lateral veins 14-18 per side, departing midrib at ca. 45° angle, sunken above, raised below, almost straight to the collective vein; interprimary veins sunken above, raised below; collective vein arising from the base, 5-8 mm from the margin, sunken above, raised below. INFLORESCENCE erect-spreading, longer than the leaves; peduncle 25-49 cm long, 5-7 mm diam., conspicuously 1-4-ribbed, 3-7 times longer than petioles; spathe subcoriaceous, pale green, oblong or oblong-lanceolate, 11-15 cm long, 1.5-2.7 cm wide, broadest near or above the middle, abruptly acuminate at apex, obtuse at base, inserted at ca. 70° angle on peduncle; spadix green to yellow, turning reddish, 5-18 cm long, 3-10 mm diam. at base, 2-6 mm diam. at apex, held at 180° angle from peduncle; flowers rhombic, 2.5-3.5 mm long, 1.5-3.5 mm wide, the sides straight to slightly sigmoid, 3-5 flowers visible in the principal spiral, 7-9 flowers visible in alternate spiral; lateral tepals 1-1.5 mm wide, the inner margin straight to convex; pistil slightly raised at anthesis; stigma ca. 0.8 mm long, oblong, brush-like, exserted; anthers (dry) ca. 3 mm long, 5 mm wide; thecae ellipsoid, scarcely divaricate. INFRUCTESCENCE spreading-pendent; spathe reflexed, sometimes absent; spadix 11-45 cm long, 1-1.5 cm diam.; berries red, oblong-elliptic, moderately acute toward apex, 6-10 mm long, prominently exserted.
