Anthurium oreodoxa Sodiro

Stem erect, robust. Cataphylls triangular-lanceolate, 20 - 25 cm long, 5 - 6 cm wide, subcoriaceous, when mature decomposing into interwoven fibres. LEAVES: Petioles crowded, erect, rigid, subequal to the blades, not very compressed laterally, thickened at the base, shortly sheathed, semi-terete abaxially, adaxially 1-sulcate, the sulca with acute aides, geniculum flattened adaxially. Leaf blade coriaceous, intensely green, abaxially densely black-punctate, adaxially more sparsely so, 35 - 40 cm long, 24 - 28 cm wide, sub-elliptic, upwards very weakly asymmetric, more-or-less acute at the base, obtuse at the apex, 7 - 9 -veined; primary lateral veins: the four innermost ending with the midrib in the apex of the blade, the rest running out into the margin gradually in succession towards the base, all, including the secondary veins, immersed adaxially and exserted abaxially. INFLORESCENCE: Peduncle thicker than the petiole and a little less than twice as long, compressed, many-sulcate when dried. Spathe densely cartilagineous, oblong-lanceolate, 15 - 20 cm long, 3 - 4 cm wide (at the middle), semi-clasping at the base and long-decurrent, terminating in a callose apex. Spadix with a short 5 - 7 mm long stipe, erect, cylindric, yellow at anthesis, 15 - 18 cm long, 1 cm thick, enlarged at maturity, purple, styles barely prominent at flowering, but in the mature spadix long-overtopping the tepals and subtetragonal.
