Anthurium cerropirrense Croat

Epiphyte; stems elongate 20 cm or more long; internodes 0.8-1 cm long; roots few, thick, green; leaf scars 1.5-2 cm wide; cataphylls subcoriaceous, 15-17 cm long, acute at apex, drying brown, persisting briefly intact, soon deciduous. LEAVES spreading; petioles 26-47.5 cm long, terete; geniculum 1.5-2.5 cm long; blades subcoriaceous, lanceolate to narrowly elliptic, long acuminate at apex, acute to broadly rounded at base, 23-48 cm long, 5.5-13 cm wide, broadest at the middle or just below; both surfaces matte to semiglossy with numerous, minute raphide cells; midrib scarcely raised, convex at base, more acute at middle, sunken at apex above, prominently and convexly raised below; primary lateral veins 12-14 per side, departing the midrib at 35-45° angle, arcuate to collective vein, sunken above, raised below; interprimary veins flat above, prominulous below; collective vein arising from one primary lateral vein usually in the lower one-third of the blade, sunken above, raised below, 4-7 mm from the margin. INFLORESCENCE spreading, shorter than leaves; peduncle 28-60 cm long, 2.5-3 mm diam., terete, ca. 2 times longer than petioles; spathe moderately thin, green (B & K Yellow-green 6/7.5), linear-lanceolate, 5.5-10 cm long, acuminate at apex, obtuse to acute at base, inserted at 65-70° angle: stipe 3-7 mm long; spadix pale olive green, 11-12 cm long, 5-6 mm diam. near base, narrowly tapered at apex; flowers rhombic to 4-lobed, 2-2.6 mm long, 2-2.4 mm wide, the sides straight to weakly sigmoid, 4-7 flowers visible in the principal spiral, 7-10 flowers visible in the alternate spiral; tepals matte to semiglossy, minutely papillate, lateral tepals 1-1.8 mm wide, the inner margin straight to weakly concave; pistils emergent, tinged violet purple; stigmas green. oblong-elliptic, 0.5 mm long; stamens emerging in a scattered manner beginning at base, laterals emerging one at a time, the third and fourth stamens emerging several days after laterals, exserted on translucent filaments ca. 3 mm long- retracting to hold anthers at level of tepals; anthers pale yellow-orange, 0.3-0.5 mm long, 0.5-0.7 mm wide; thecae ovate-elliptic, weakly divaricate; pollen yellow-orange, fading to white. INFRUCTESCENCE probably with purple berries, acute at apex, ca. 8 mm long, ca. 3 mm wide (dry).
