    Distribution

    Anthurium arisaemoides ranges from Ecuador (Pastaza, Morona-Santiago, Zamora-Chinchipe) to Peru (Loreto) at 300-2,000 m in Tropical moist forest and Tropical wet forest life zones (Holdridge, 1971).

    General Description

    Terrestrial herb usually low to the ground but sometimes erect to 1.5 m, sometimes an epiphytic creeper to between 30 cm and 1.5 m; stems usually moderately short; internodes elongate (1-)3-10.5 cm long, 6-18 mm diam., medium to dark green or gray-brown, matte to semiglossy; cataphylls 4-7.5 cm long, green tinged purple, uppermost intact, deciduous or persisting as white membranaceous fibers at upper nodes. LEAVES evenly spaced along an elongate stem; petioles 9-41 cm long, 2-3 mm diam., terete or obtusely D-shaped or flattened, narrowly and shallowly or bluntly sulcate abaxially, slightly paler and rounded abaxially, dark yellow-green to medium green to purple-violet, weakly glossy to semiglossy; geniculum 12 mm long, swollen, especially abaxially, narrowly sulcate adaxially; blades trisect, 8-29.5 cm long, 10-30 cm wide, broadest at the middle, conspicuously bullate, subcoriaceous, light green to dark green and semiglossy to matte or weakly glossy above, moderately paler, matte to weakly glossy and net-sunken below; medial segment 12-21 cm long, 4-9 cm wide; lateral segment markedly inequilateral, 6.5-19 cm long, 2-10.5 cm wide, one side 3-13 mm wider; midrib narrowly or bluntly acute or raised and concolorous above, thicker than broad, narrowly rounded and slightly paler or reddish purple below; primary lateral veins thicker than broad, etched-sunken and concolorous above, bluntly acute, narrowly raised, convex and concolorous below; primary lateral veins on medial segment number 3-4, the 1st being a collective vein that approaches and parallels the margin at a slight inset, also marked by numerous scarious veins (visible at 30X magnification); primary lateral veins on lateral segment number 2-3 with each vein also being a collective vein with numerous scarious veins running in between; tertiary veins moderately obscure, weakly etched or deeply sunken above, obscure or raised below. INFLORESCENCES axillary, erect; peduncle half as long as petiole, terete, erect, purplish red, densely greenish speckled, 5 mm diam., weakly glossy; spathe ovate to oblong-linear, 3.2-8.3 cm long, 1-2.5 cm wide, reflexed, oblong, shorter than spadix, pale to medium green, tinged purple, erect-spreading, matte to semi-glossy outside, weakly to semiglossy inside reflexed, twisted; spadix sessile or with stipe 2-5 mm long, tapered, erect, 3-9 cm long, 6-8 mm diam. near base, 5-6 mm diam. at 1 cm from apex dark, yellow-green to pink, usually becoming purple at anthesis, weakly glossy to matte. Flowers 6-7 visible per spiral, 1.9-2 mm long, 2.1-2.2 mm wide, dark brown, conspicuously pale granular; lateral tepals 2.0-2.5 mm wide, narrowly shield-shaped or with outer margin 2-sided, inner margin rounded. INFRUCTESCENCE with spadix purplish violet; berries green, early emergent, ovoid, medium green, dark green at tip; flowers sub 4-lobed, difficult to discern, 5-6 per spiral; tepals shield-shaped, inner margin rounded, outer margin bluntly triangular.

    Habitat

    At the type locality in the Cordillera de Cutucu, A. arisaemoides grows terrestrially in dense stands in the forest understory and in its general aspect it is remarkably similar to Arisaema. The species frequently grows on soil in small groups or sometimes at the base of trees in moss.
