Anthurium oxyphyllum Sodiro

Epiphytic; stem short, (1)1.5-2 cm diam.; roots dense, numerous, ascending to spreading, green, smooth when young, soon becoming tomentose, slender and elongate, to 13 cm long, 2-6 mm diam.; cataphylls membranous, 7-10 cm long, narrowly rounded at apex with subapical apiculum ca. 8 mm long, drying tan (B & K yellow 9/2.5), persisting as fine linear fibers. LEAVES spreading; petioles 6-25(30) cm long, 4-7 mm diam., D-shaped, flattened to convex to weakly sulcate or occasionally with a medial rib adaxially, the margins sharply raised, rounded abaxially; geniculum thicker and paler than petiole, (0.7)l-2 cm long; blades coriaceous, narrowly elliptic to sometimes narrowly oblanceolate, long-acuminate at apex (the acumen flat), long-attenuate at base, 45-70 cm long, (4)6-11 cm wide, broadest at or near the middle, the margins broadly undulate; upper surface matte, dark to bright green, lower surface glossy to semiglossy, paler; both surfaces drying matte, greenish to yellowish brown; midrib flat to convexly raised above, prominently and acutely raised and paler than surface below; primary lateral veins 25-35 per side, departing midrib at 30-60° angle, ± straight to the collective vein, scarcely raised to flat or weakly sunken above, weakly raised to ± obscure below, drying slightly raised above and below; interprimary veins numerous, almost as conspicuous as primary lateral veins, obscure when fresh, weakly raised when dried; tertiary veins visible when dried; collective vein arising from near the base, equally as prominent as primary lateral veins, raised when dried, 3-6 mm from margin. INFLORESCENCES pendent to erect-spreading, shorter than leaves; peduncle (21)24-46 cm long, (3)4-5 mm diam., 1.2-6 x as long as petiole, light green tinged with purple or maroon at least at base, terete to subterete and flattened adaxially; spathe deflexed green to yellow-green (B & K yellow-green 6/10), cylindroid, semi-erect to nodding, usually slightly curved, held at (150)l30-60° angle from peduncle, 5.8-11 cm long, 3-7 mm diam. near base, 3-5 mm diam. near apex; flowers ± rhombic to 4-lobed, 3-4.5 mm long, 3.7-4.3 mm wide, the sides straight to smoothly or sometimes jaggedly sigmoid; 5-7 flowers visible in principal spiral, 6-8 in alternate spiral; tepals brown, matte to semiglossy, minutely papillate, with abundant droplets present; lateral tepals 1.3-2.5 mm wide, the inner margins broadly convex to straight, scarcely turned up against the pistil, the outer margins 2-sided; pistils prominently emergent, exserted and papillate, the exposed portion squarish, green becoming dark purple; stigma linear to ellipsoid, ca. 0.4 mm long, weakly raised, copious droplets appearing before the stamens emerge; stamens emerging in a regular sequence throughout, held well above the tepals, lateral stamens emerging almost to apex before alternates begin to emerge, arranged in a circle around the pistil; filaments transparent, prominently exserted, thin and flattened, 1.5-1.7 mm long; anthers orange, becoming pinkish or reddish brown, ca. 0.8 mm long, 0.9 mm wide; thecae oblong-ellipsoid, scarcely divaricate; pollen orange, fading to white or tan. INFRUCTESCENCE with spathe persisting; spadix 9.5-11.5 cm long, 1-1.5 cm diam., with berries scattered throughout; berries orange, ellipsoid, acute and with radial ridges at apex, 6.8-7 mm long, 3.2-3.7 mm diam.; mesocarp mealy; seeds 1 per berry, yellow-brown when dried, ± ovoid, truncate at both ends, 3.5-5 mm long, 2.2-3 mm diam., 1.5- 1.6 mm thick, enveloped by gelatinous, translucent, amber substance.
