    Conservation

    Conservation for Anthurium debilipeltatum must be considered as Near Threatened (NT) according to IUCN Red List criteria (IUCN, 2001). Although locally common in the area of the type locality, it is not yet known from other sites in Peru. The type locality is extremely rocky and unsuited to agriculture, so there is a good chance that this region will be preserved. In addition, the species no doubt occurs in an adjacent area with the same type of vegetation that is already in a nature reserve around Cueva de las Lechuzas.

    Diagnostic

    Ecology

    Anthurium debilipeltatum is endemic to Peru in the Department of Huanuco, known only from the limestone cliffs in the hills east of the Rio Huallaga near Tingo Maria at 675 to 800 m elevation in Premontane wet forest transition to Tropical (P-wf/T) life zone.

LEAVES pendent to suberect; petioles 5-18 cm, 13 mm diam., terete, drying yellowish green, inserting slightly above the leaf base; geniculum concolorous and thicker than petiole, 0.5-1.5 cm; blades lanceolate to oblong-elliptic, subcoriaceous to coriaceous, gradually acuminate at apex, obtuse to rounded at base, 13-27 X 1.5-4 cm, broadest in the lower 1/3 or near middle, adaxial surface dull green, abaxial surface shiny green, drying bicolorous yellowish green; midrib weakly and narrowly raised adaxially, convexly raised abaxially, drying paler than surface on both sides; primary lateral veins 15 to 25 pairs per side, departing midrib at 80°-45°, mostly straight to the collective vein, scarcely or not raised on either surface when fresh, drying weakly raised on both surfaces; interprimary veins almost as conspicuous as primary lateral veins when dried; lesser veins visible when dried; collective vein arising from the base, 1 4 mm from margin. INFLORESCENCES erect; peduncle 5-19 cm, drying ca. 1 mm diam., drying light yellowish green; spathe lanceolate, 2.5-5 X 0.5 0.7 cm, acuminate at apex, chartaceous, reflexed, medium green, drying green, broadest in lower 1/3; stipe 3-9 mm in front, 2-5 mm in back; spadix usually weakly tapered to cylindrical, 4.4-7.4 cm, 2 5 mm diam. near base, 2-3 mm diam. near apex, broadest at the base, yellowish green to grayish green, drying yellowish green. Flowers square, 17-21 mm in both directions, sides straight to smoothly or jaggedly sigmoid, 4 or 5 flowers visible in principal spiral, 3 or 4 flowers visible in alternate spiral; tepals matte, lateral tepals 1-1.2 mm wide, inner margins straight to weakly convex, outer margins angled, 2-sided; pistils weakly exserted, drying pale green; stigma ellipsoid, 0.4-0.7 mm, drying dark brown. INFRUCTESCENCE with spathe absent; spadix with berries in the basal portion only; berries depressed-globose, 2 2.5 mm, 3-5 mm diam., white, drying pale green, apex broadly rounded; seeds 2, obovoid-flattened, 2.2-2.6 mm, 2.2-3.5 mm diam., ca. 1.5 mm thick, pale brown with white-speckled surface.
