Anthurium coriaceum G.Don

Terrestrial or epilithic, sometimes epiphytic; stem less than 20 cm long, 1.5-3.5 cm diam.; roots mostly descending, to 5 mm diam.; cataphylls coriaceous, unribbed, broadly lanceolate, 12- 14 cm long, acute to obtuse at apex, drying straw-colored, becoming brown toward base, persisting semi-intact. LEAVES erect-spreading; petioles (3)19-60 cm long, (4)l0- 15 mm diam., terete, sometimes obtusely flattened adaxially, the surface sometimes pale-speckled; geniculum moderately thicker and paler than petiole, 1-2.5 cm long; sheath 4-5.5 cm long; blades coriaceous, broadly elliptic to somewhat oblong, sometimes somewhat lanceolate or oblanceolate, acute to rounded and minutely apiculate at apex, acute to obtuse or rounded (rarely shallowly cordate) at base, (35)60-110 cm long, (6)15-28(39) cm wide, broadest usually above the middle, the margins moderately undulate; upper surface matte to weakly glossy, medium green, lower surface semiglossy, slightly paler; midrib above flat to broadly convex at base, becoming convexly to acutely raised toward apex, prominently convex below; primary lateral veins numerous, departing midrib at (40)50-70(80)° angle, straight to slightly arcuate to the collective vein, weakly sunken to weakly raised and obscure above, similar but more visible below, raised above and below when dried; interprimary veins almost as conspicuous as primary lateral veins; tertiary veins prominulous above and below on drying; collective vein arising near the base, equally as prominent as primary lateral veins, 5-20(30) mm from margin. INFLORESCENCES erect; peduncle 11-44 cm long, (3)5-9 mm diam., (0.2)0.5-1.7(3.6) x as long as petiole, terete; spathe erect, coriaceous, green, broadly lanceolate-elliptic, (7.5)10-24 cm long, (1.7)2.5-4.3 cm wide, broadest near the base, acute to acuminate at apex, acute at base; spadix pale purplish to maroon, sessile, tapered, erect, straight to slightly curved, 10-31 cm long, 8-12 mm diam. midway, 4-5 mm diam. near apex; flowers rhombic, 2.5-3.1 mm long, 1.8-2 mm wide, the sides straight to weakly sigmoid; 13-23 flowers visible in principal spiral, 8- 14 in alternate spiral; tepals matte, smooth; lateral tepals 1.6-2 mm wide, the outer margins 2-sided, the inner margins rounded; stigma oblong-ellipsoid, 0.5 mm long, depressed medially; anthers 0.5-0.7 mm long, 0.6-0.7 mm wide, inclined over and obscuring pistil; thecae ovoid-oblong, slightly or not divaricate; pollen pale yellow on drying. INFRUCTESCENCE erect; spathe persisting; spadix to 18 cm long, 2 cm diam., with the berries scattered throughout; berries dirty white to pale lavender, greenish at apex, obovoid-oblong, truncate at apex, 7 mm long, 5 mm diam., the pericarp with raphide cells; seeds 2 per berry, ovoid-ellipsoid, 4.5-5 mm long, 3-3.5 mm wide, 1.7-2 mm thick, flattened on one side, oblique and with a short, hooked appendage at apex.
