Anthurium rupicola Croat

Epipetric; stems less than 10 cm long, 1-1.5 cm diam.; internodes short; leaf scars hidden by cataphylls; roots numerous, descending, ca. 3 mm diam.; cataphylls 3-4.5 cm long, thin, green, acuminate at apex, promptly weathering to fine, tan, persistent fibers. LEAVES erect-spreading; petioles terete to ellipsoid in cross-section, or flattened adaxially with a medial rib, 8-19 cm long, usually one-half to three-fourths as long as the blade; geniculum ca. 1 cm long; blades subcoriaceous, narrowly oblong-elliptic to rarely lanceolate-oblong, gradually acuminate at apex (the acumen apiculate), narrowly acute at base, 14-22 cm long, 2.2-4 cm wide, broadest usually at the middle; both surfaces semiglossy, drying more or less matte, sparsely and inconspicuously glandular-punctate on the upper surface, conspicuously glandular-punctate on the lower surface; midrib prominently raised on both surfaces; primary lateral veins 8-10 per side, scarcely or not at all more conspicuous than the interprimary veins, departing midrib at 55°-70° angle, straight or weakly curved to the collective vein; interprimary veins numerous, drying prominulous on both surfaces; collective vein sunken above, raised below, generally more prominent than the lateral veins, inconspicuously loop-connecting the primary lateral veins. INFLORESCENCE erect-spreading, usually several per plant at flowering time; peduncle terete, 12-28 cm long, 2-3 mm diam.; spathe green, moderately thin, lanceolate, 2.5-4.7 cm long, 5-10 mm wide, broadest usually just above the base, abruptly to gradually acuminate at apex, acute at base, inserted at 45° angle on peduncle; stipe usually to 5 mm long; spadix white at anthesis, moderately tapered to apex, 2.5-4.5 cm long, 3-5 mm diam. near the base, 2-3 mm diam. near the apex; flowers subquadrangular, 2-2.6 mm long, ca. 2.5 mm wide, 3-4 flowers visible in the principal spiral, 4-6 visible in alternate spiral; tepals semiglossy, the lateral tepals 1-1.4 mm wide, the inner margin thin, obtusely angular, stamens retracted after anthesis; anthers 0.6 mm long, 0.8 mm wide, thecae ovoid, divaricate; pistil early emergent and beginning to color long before maturity. INFRUCTESCENCE erect; berries (dried) subglobose, beaked at apex, red to violet purple, 4-5 mm diam.; seeds 2, tan to brown, 2.4÷2.8 mm long, 1.8-2.1 mm diam., 1-1.3 mm thick, encased in a thin, gelatinous envelope, scarcely elongate at either end.
