Anthurium umbricola
Terrestrial or epiphytic; plants 30-150 cm tall; internodes 2.5-4 cm long, 5-10 mm diam., drying black; cataphylls 4--6 cm long, drying reddish brown, persisting semi-intact or as a reticulum of fibers at upper nodes, as a loosely organized reticulum of fibers lower nodes; petioles 12-28(42) cm long (averaging 20.3 cm), 2-4 mm diam., erect-spreading, drying dark brown, C-shaped, bluntly D-shaped with weakly erect margins, ranging from having a weak medial rib to being canaliculate; geniculum 1-1.3 cm long, drying black, darker than petiole or blade; blades narrowly ovate to ovate-elliptic, acuminate at apex, acute to rounded at base, 12-24 cm long, 7-13 cm wide (averaging 20 x 10 cm), 1.7-2.6 times longer than broad, .6-1.4 times longer than the petioles, broadest at or somewhat below middle, subcoriaceous to thinly coriaceous; both surfaces semiglossy, moderately bicolorous; upper surface drying dark reddish brown, lower surface drying moderately paler; midrib narrowly convex and slightly paler above, acute and slightly paler below, drying dark brown, similar in color to petiole below; primary lateral veins 11-14 per side, departing midrib at 45°-60° angles, etched to etched-sunken above, convex below; interprimary veins almost as prominent as primary lateral veins; collective vein arising from one of first primary lateral veins, 2-4 mm from margin; INFLORESCENCES erect to erect-spreading; peduncle 18-36 cm long, 1-3 mm diam., drying a medium reddish brown; spathe spreading to reflexed, chartaceous, green or reddish, linear, curled down along margins, 2-5 cm long, 2-3 mm wide; spadix medium green, stipitate, cylindroid, 5--6 cm long, 2-4 mm diam.; tepals medium green, semi-glossy; pistils yellowish. INFRUCTESCENCES (not fully mature) with tepals dark green, widely separated from one another; berries white, weakly emergent.
Anthurium umbricola ranges from Colombia (Antioquia, Cauca, Narino, Valle del Cauca) to Ecuador (Azuay, Bolfvar, Cafiar, Cotopaxi, El Oro, Esmeraldas, Guayas, Los Rios, Manabi, Pichincha), at elevations of 250-2,100 m in Tropical dry forest, Premontane dry forest, Premontane wet forest, Tropical wet forest, Premontane rain forest and Lower montane dry forest. This species is quite common throughout La Planada. A member of sect. Polphyrochitonium, this species is apparently quite variable especially in blade shape and venation, but it is characterized by its typically terrestrial habit, C- to D-shaped petioles exceeding more or less ovate, black-drying blades which are acute to rounded at base. Also characteristic is the short spadix.
