Anthurium durandii Engl.

Epiphytic or rarely terrestrial; stems short; internodes sometimes to 3 cm long; roots short, sometimes purplish; cataphylls moderately thin, 5.4-6 cm long acuminate at apex, drying pale brown, weathering to reticulate fibers, ultimately deciduous. LEAVES erect-spreading; petioles 9-25 cm long, 4-5 mm diam., broadly and sharply sulcate adaxially, rounded abaxially, sparsely, dark glandular-punctate; geniculum 1.5-3 cm long; blades elliptic, coriaceous, short-acuminate at apex, obtuse at base, 10-31 cm long, 4-15 cm wide, broadest near middle; both surfaces matte, dark glandular-punctate, the lower surface paler, the upper surface drying with an alveolate pattern; midrib convexly raised at base above, acute al middle, weakly sunken toward apex, convexly raised below, narrowing toward apex; primary lateral veins 8-15 per side, departing midrib at 45° angle, straight to collective vein, flat to weakly sunken above, raised below, lesser veins obscure; collective vein arising from the base, 9-15 mm from the margin, a secondary collective vein sometimes extending to about the middle of the blade. INFLORESCENCE spreading, shorter than or equalling leaves; peduncle 12-40 cm long, ca. 3 mm diam.; spathe moderately thin, pale green to pinkish green (B & K Yellow-green 7/7.5), oblong-lanceolate, 4-7 cm long, 1-1.5 cm wide, broadest near the base, abruptly acuminate at apex, acute at base, inserted at ca. 65° angle on peduncle; spadix pale green turning reddish brown, narrowly tapered toward apex, 10-16.5 cm long, 4-9 mm diam. at base, 2-4 mm diam. at apex; flowers 4-lobed, 3-4 mm long, 2.5-3 mm wide, the sides straight in the direction of the principal spiral, sigmoid perpendicular to the spiral; ca. 3 flowers visible in the principal spiral, ca. 5 flowers visible in the alternate spiral; tepals semiglossy, lateral tepals 1.8-2.2 mm wide, the inner margin convex; pistils emergent but not raised, square, green; stigmas scarcely visible, ca. 0.2 mm long, drying black; stamens emerging from the base, laterals first, scarcely exposed, quickly retracting before alternates emerge; pollen white. INFRUCTESCENCE with spadix to 22 cm long; berries ovoid, probably orange.
