Anthurium caperatum Croat & Baker,

Brenesia 16(Supl. I): 32. 1979. TYPE: Costa Rica. Heredia: vicinity Bajo la Hondura, along road between Paracito and the Río Claro, 1,100-1,400 m, Croat 44518 (MO 2598657-58, holotype; CR, F, K, NY, US, isotypes).

Epiphytic near the ground or terrestrial; stem 60-120 cm long, 2.5-5 cm diam.; cataphylls drying pale brown, weathering into fine fibers; petioles 24-109 cm long, 6-15 mm diam., sub-terete, shallowly and bluntly sulcate; blades ovate to narrowly ovate, subcoriaceous, usually weakly bullate, prominently lobed at base, 46-120 cm long, 30-69 cm wide. Inflorescence erect; peduncle 6-54 cm long, 8-13 mm diam., subterete or terete; spathe thin, pale green, lanceolate-oblong, 10-28 cm long, 3.3-4.8 cm wide; spadix sessile, pale green (3-)7-18(-28) cm long, 10-20 mm diam. at base; berries greenish white to yellowish green at base, ovate to ovate-elliptic, to 9 mm long, ca. 5 mm diam.; seeds 2. See Croat (1983: 261) for a more complete description.

The species is known from Costa Rica and Panama and is to be expected in Colombia on the southwestern slopes of the Serrania de Pirre. It occurs on both the Atlantic and Pacific slopes. In Costa Rica, it ranges from 850 to 2,000 m but in Panama it has been collected as low as 400 m. The species inhabits premontane wet, premontane rain, and lower montane rain forest.

Anthurium caperatum is in section Polyneurium and is recognized by its large, ovate slightly bullate leaves, its green brittle spathe, its pale green spadix, and its greenish berries. The species is similar to A. panamense, but that species has more elongate blades that are glossier on the upper surface, less protruded styles, weakly ribbed petioles, and red berries. Collections from Darien Province of Panama are unusual with spadices more slender and relatively longer, a generally thinner spathe (drying membranous), and some of the specimens have the collective vein relatively more remote from the margin (Folsom 4365 is particularly noteworthy in this respect). The specimens involved, Croat 37790, Folsom 4232. 4365, 4517. and 6320, may ultimately prove to be a distinct species. With the exclusion of these collections, the species ranges no further east than Cerro Campana in Panama Province.
