Anthurium bernalii
Terrestrial as juvenile or preadult, usually epiphytic as adult; juvenile plants with petioles 15-20 cm long, 1-2 mm diam., blades ovate-triangular, slightly to moderately cordate, 15-20 cm long, 5-9 cm wide; adult plants with internodes to 5 cm long, 1.5-4 cm diam.; cataphylls persisting intact at upper nodes, as linear bases of fibers at lower nodes, 12-16 cm long, drying medium tan; petioles 70-100 cm long (averaging 73.3 cm),4-7 mm diam. at middle, terete, sometimes tinged maroon; blades ovate-triangular, acuminate at apex, cordate at base, (25-) 55-81 cm long, (11.3-) 27-44 cm wide (averaging 72.2 x 35.6 cm), 1.8-2.2 times longer than broad, .8-1.0 times longer than the petioles, broadest at or slightly above point of petiole attachment (sometimes broadest below the petiole attachment), subcoriaceous; surfaces slightly bicolorous, drying medium olive; upper surface semiglossy and bullate; lower surface matte; anterior lobe 33-65 cm long, broadly convex to slightly concave along the margin; posterior lobes 13-21 cm long, 12-20 cm wide, directed either inward or outward; sinus spathulate to parabolic, 7-10 cm deep, 5-9 cm wide; midrib convex and paler than surface above, round-raised and paler than surface below; basal veins 6-7 pairs, first one or two free to base, the remainder coalesced for 2-3 cm; posterior rib naked for 1-2 cm; primary lateral veins (20-)25-30 per side, sunken above, raised below; interprimary veins nearly as conspicuous as primary lateral veins; collective vein arising from one of basal veins, 2-5 mm from margin; all other veins prominently sunken above, prominently raised below. INFLORESCENCES erect-spreading; peduncle 30-55(-70) cm long, 3-5 mm diam. at middle; spathe lanceolate, 12-13 cm long, 1 cm wide, green, reddish green, or light green; spadix green or brownish green, becoming purplish before anthesis, weakly glossy, narrowly tapered, 22.5-34 cm long, 5 mm diam. near middle, 3.5 mm diam. at 1 cm from apex. Flowers visible 5-7 per spiral, 2.3-2.5 mm long, 1.7-1.9 mm wide; tepals minutely granular, lateral tepals 1.0-1.3 mm wide, the outer margins 3-4 sided (shield-shaped); pistils green, acute, early emergent. INFRUCTESCENCES to 40 cm long, moderately dark green; tepals green in early fruit.
Anthurium bernalii is now known only from Colombia (Narino) and adjacent Ecuador (Carchi), at elevations of 1,450-2,390 m, in Premontane wet forest. A member of sect. Polyneurium, this species is recognized by its moderately short internodes, the persisting fibrous cataphylls, terete petioles and especially by the conspicuously bullate, ovate-triangular blades as well as by its long, slender green spadix which turns purple before anthesis. It is apparently quite frequent at La Planada, having been collected several times by different botanists throughout the Reserve.
