    Distribution

    Anthurium chacoense is at present known only from northern Ecuador (Napo, Sucumbios) at 1,000-1,850 m elevation in Premontane wet forest, Premontane rain forest life zones. It is to be expected in adjacent Putomayo Department of Colombia.

    General Description

    Epiphyte; caudex short; internodes short, to 3.5 cm diam.; cataphylls membranaceous, red-brown, 11-30 cm long, 2-4 cm wide, semi-intact at apex, weathering quickly at base to brown fibers surrounding the base of the caudex. LEAVES clustered at the base of the plant; petioles medium green, semiglossy, subterete, narrowly and obtusely sulcate, geniculate at apex, 46-85 cm long, ca. 8 mm diam.; geniculum ca. 10 mm long; blades narrowly ovate-sagittate, cuspidate at apex, 35-80 cm long, 18-47 cm wide, averaging 56 X 34 cm, 1.2-2.4 times longer than wide, .6-1.4 times as long as petioles, subcoriaceous, dark green and glossy above, paler green and glossy below; anterior lobe usually broadly rounded to straight or slightly concave; midrib slightly paler with a narrow medial wing, convex with an acute rib below, drying concolorous and narrowly acute; primary lateral veins 9-10 pairs, rising at an acute angle then spreading at 40-45° angle, narrowly raised in valleys above, drying narrowly raised and concolorous, acute and paler than the blade below, drying slightly darker with an acute medial rib below; collective veins arising from (1st) 4th-5th pair of basal veins, 2-5 mm from margin; basal veins (4-)8-12, 1st pair free to base, the remainder coalesced to varying degrees and regularly branching from the posterior rib; posterior rib thick, broadly curved, naked (3.7-)7-12.5 cm; sinus narrowly hippocrepiform to spathulate, sometimes with the posterior lobe markedly turned inward. INFLORESCENCES erect; peduncle terete, narrower and shorter than petioles, 9-60 cm long, 2-4 mm diam.; spathe membranaceous, hooding, oblong to elliptic, clasping the base of the stipe, 5-17 cm long, .9-3.8 cm wide, 1.1-4.8 times shorter than peduncles, green or red-purple; spadix stipitate 5-10 mm, cylindrical, often more or less curved, usually purple but sometimes pink or red at different stages of development, matte, 7-20 cm long, 5-12 mm diam. Flowers 9-10 visible per spiral, 2-2.1 mm long, 1.7-1.8 mm wide (dried); lateral tepals densely granular on magnification, 1-1.3 mm wide, the outer margins 2-sided, inner margins broadly rounded; stamens exserted ca. 1 mm and remaining exserted; anthers .4-.6 mm long, .4 mm wide; thecae ovoid, weakly divaricate. INFRUCTESCENCE semi-erect, to 23 cm long; berries drying ca. 2 mm diam., subglobose, purplish violet.
