Anthurium cuyabenoense Croat

Epiphyte; caudex slightly elongate, rooting at the nodes, densely covered along its length by roots, remaining bases of petioles and remnants of cataphylls; internodes short to slightly elongate, 1-2 cm long, ca. 2 cm diam.; cataphylls membranaceous, 11-19 cm long, semi-intact at apex, weathering quickly at base to brown fibers surrounding the caudex, ultimately deciduous with scaly bases remaining around the stem. LEAVES moderately thin, concentrated at the top of the caudex; petioles subterete, slightly geniculate at apex, 39-77 cm long, ca. 8 mm diam.; geniculum ca. 8 mm long; blades broadly cordate and concave near the middle, cuspidate at apex, 37-80 cm long, 22-56 cm wide, averaging 53 x 38 cm, .8-1.7 times longer than wide, .7-1.4 times as long as petioles, moderately thin, dark green and glossy above, pale green and glossy below; midrib raised above, prominently raised and darker than the blade below; primary lateral veins (8-)10-17 pairs, rising at an acute angle then spreading at 40-60° angle, raised above, strongly raised and darker than the blade below, concolorous with midrib; collective veins arising from 4th-5th pair of basal veins, 2-5 mm from margin basal veins (6-)7-10, 1st pair free to base, the remainder coalesced to varying degrees and regularly branching from the posterior rib; posterior rib thick, broadly curved, 5-9.5 cm; sinus broadly to narrowly hippocrepiform, sometimes with the posterior lobe turned inward. INFLORESCENCES erect; peduncle terete, thinner and shorter than petioles, 16-60 cm long, 2-4 mm diam.; spathe membranaceous, spreading, oblong to elliptic, acuminate at apex, obtuse at base, clasping the base of the stipe, 6.5-14 cm long, 1.6-3.5 cm wide, 2.3-5.2 times shorter than peduncles, white, cream-colored, light brown or green; spadix stipitate 4-8(-15) mm, 9-25 cm long, 5-8 mm diam., cylindrical, often more or less curved, usually red or dark red, sometimes purplish red. Flowers 6-7 visible per spiral, 2.4-2.6 mm long, 2.2-2.6 wide; lateral tepals 1.8-1.9 mm wide, densely granular on drying, the outer margin 2-sided, the margin rounded. INFRUCTESCENCE somewhat deflexed; spadix up to 32 cm long, 1.2 cm wide; berries bright red.
