Anthurium chocoense Croat

Rupicolous herb; stems short; internodes short, 8-15 mm diam.; roots numerous; leaf scars hidden by cataphylls; cataphylls 5.5-6.5 cm long, briefly intact, then weathering into fine, pale fibers; petioles subterete, weakly sulcate adaxially, 8-23 cm long, 0.5-0.7 the length of the blades; geniculum 8-15 mm long, drying darker than surface; blades subcoriaceous, narrowly oblong-elliptic, gradually acuminate at apex, narrowly acute at base, 21-28 x 1.5-2.7 cm, broadest usually at the middle; upper surface dark green and iridescent, lower surface yellow-green, both surfaces drying matte to weakly glossy, epuncate on the upper surface, inconspicuously and densely pale-punctate on the lower surface (punctations irregularly shaped, raised, but not apparently glandular); midrib convex and concolorous above, drying prominently raised, narrowly raised and paler below, drying raised and irregularly ridged; primary lateral veins many, not at all distinguishable from the interprimary veins upon drying, departing midrib at 20-50° angle, straight or weakly curved to the collective veins, weakly sunken above and about as prominent as collective veins, raised below and more prominent than primary lateral veins, drying prominently raised on both surfaces; interprimary veins numerous, drying prominulous on both surfaces; collective veins drying raised on both surfaces, generally more prominent than the lateral veins, not loop-connecting the primary lateral veins. INFLORESCENCE erect-spreading, usually several per plant at flowering; peduncle terete, 30-53.5 cm long, 2-3 mm diam.; spathe green, subcoriaceous, narrowly lanceolate, 3.5-4 cm x 5-8 mm, broadest usually just above the base, abruptly to gradually acuminate at apex, acute at base, inserted at 45° angle on peduncle; spadix white at anthesis, becoming green post-anthesis, weakly tapered to apex, 3.7-6.0 cm x 3-6 mm near the base, 2-3 mm diam. near the apex. Flowers subquadrangular, 2.0-2.2 X 1.4-1.6 mm, 5-6 flowers visible in the principal spiral; tepals semiglossy, the lateral tepals 2-2.2 mm wide, the inner margin thin, broadly rounded, outer margin obtusely 2-3-sided. INFRUCTESCENCE not seen, but berries white (fide Idrobo 1901).
