Anthurium testaceum Croat & Baker,

Brenesia 16(Supl. I): 92. 1979. TYPE: Costa Rica. Alajuela: Atlantic side of Alto de las Palomas, 1,900 m. Lent 1820 (F, holotype).

Epiphytic or terrestrial; stems elongate, ca. 1 m long, 1-1.5 cm diam.; cataphylls drying greenish yellow to brown, weathering and often persisting, ultimately deciduous; petioles (8-) 14÷48 cm long, 3-6 mm diam., terete; blades oblong-lanceolate to lanceolate to oblong-elliptic, moderately thin, obtuse to rounded (rarely acute) at base, 18-50 cm long, 4÷12.5 cm wide. Inflorescence spreading; peduncle 14-40 cm long, 3-5 mm diam., terete; spathe more or less thin, green lanceolate, 3-7 cm long, 7-14 mm wide; stipe 1-7 mm long; spadix green, sometimes tinged with violet purple, 4÷12 cm long, 4÷6 mm diam. at base; berries bright red, oblong-ellipsoid, rounded at apex, 10-13 mm long; seeds 2. See Croat (1983: 395) for a more complete description.

The species is found in Costa Rica and Panama from 800 to 2,000 m in premontane wet and premontane rain forest life zones. In Panama, the species is known only from western Panama near Costa Rica in the Provinces of Bocas del Toro and Chiriquí.

Anthurium testaceum is in section Xialophyllium and can be distinguished by its elongate narrow stem, its long, thin, persistent cataphylls, its bright red, prematurely exserted berries, its few-flowered spadix spirals, and by its lanceolate leaf with the midrib and primary lateral veins drying very pale tan.
