Anthurium pittieri.
var. pittieri. TYPE: Costa Rica. Heredia: Rancho Flores, Volcán Barba, 2,505 m, Pittier & Durand865 (BR, hololectotype, designated Croat & Baker, 1979).

Epiphyte, sometimes somewhat scandent; stems less than 30 cm long; internodes short, 1-1.5 cm diam., leaf scars conspicuous; roots few, descending; cataphylls subcoriaceous, (3)8-12.5(14) cm long, apiculate at apex, drying dark tan, persisting intact, ultimately deciduous.

LEAVES spreading; petioles 3-15 cm long, 4-7 mm diam., subterete, usually bluntly sulcate to weakly flattened; geniculum 2-3 cm long; blades narrowly lanceolate to lanceolate-elliptic to ovate-elliptic or oblong, moderately thick, (8.5)10-43 cm long, 1.5-9 cm wide, acuminate at apex, acute to obtuse or rarely rounded at base; upper surface matte to semiglossy, lower surface semiglossy; midrib broad and convexly raised above and below, diminished and sunken at apex above; primary lateral veins 17-20 per side, ± obscure above, prominulous to flat and ± obscure below, departing midrib at ca. 50° angle, straight to collective vein; collective vein arising near the base, weakly sunken above and prominulous below, 3-6 mm from margin.

INFLORESCENCE ± erect, usually shorter than leaves; peduncle (5)11-14 cm long; spathe green, subcoriaceous, oblong-lanceolate, (3)7-15 cm long, 1.2-2.5 cm wide, caudate-acuminate at apex, decurrent onto peduncle 1-1.5 cm, acute to attenuate at base, inserted at 80° angle on peduncle; spadix green (B & K Yellow-green 5/7.5), (2.2)11-14.5 cm long, (3)7-8 mm diam. at base, (2)4-5 mm diam. at apex; flowers rhombic, 6-6.3 mm in both directions, the sides straight to weakly sigmoid; 2-3 flowers visible in the principal spiral, 3-5 flowers visible in the alternate spiral; tepals matte, minutely papillate, larger plants with tepals usually mounded giving spadix a knobby appearance, lateral tepals ca. 5 mm wide, the inner margin straight; pistils usually exserted, green, matte; stigma elliptic, ca. 0.6 mm long, brushlike, exserted and glistening with a small droplet for 3 or 4 days ca. 2-3 weeks before anthers emerge, dry and black as stamens emerge; stamens emerging slowly in scattered manner throughout spadix, exserted on minute, green filaments that retract holding anthers at sides of pistil; anthers cream-colored ca. 0.5 mm long, ca. 1 mm wide; thecae tan, ellipsoid, not divaricate; pollen pale yellow fading to white, soon dispersing.

INFRUCTESCENCE pendent; spadix 5-15 cm long; berries yellow to orange in Panama or reportedly white in Costa Rica, obovoid, acute at apex, 1-1.5 cm long, 7 mm wide; seeds 2, green, flattened. Figs. 136 and 137.

The species is known from Costa Rica and Panama at 50 to 2,100 m elevation in tropical wet and premontane rain forest life zones. A specimen recently collected by Emesto Ancuash (1230) under the auspices of Brent Berlin's anthropological studies in Peru (Dept. of Amazonas, Río Cenepa) is apparently also this species. It would be the first collection of the species from South America.
Anthurium pittieri is a member of section Oxycarpium and is distinguished by its coriaceous, epunctale leaf blades, premature emergent berries, and especially by the long-decurrent spathe.
The species is variable in leaf blade shape and in the degree of emergence of the pistils. Smaller plants tend to have the tepals flat with the pistils not noticeably emergent while larger plants have the pistils somewhat protrudent with the lepals turned somewhat upward. Specimens with unusual leaf shape include António 2139 from Panama with oblong leaves, 6.5 times longer than wide and Croat 35295 from Dominical (Puntarenas, Costa Rica) with leaves almost as wide as long.
It is most easily confused with A. interruptum and A. carnosum, both of which differ in usually having more elongate internodes, in lacking a conspicuously decurrent spathe, and in having either green or reddish berries. Anthurium pittieri is reportedly related to A. decurrens Poepp. from
Amazonian Peru but differs from that species in having a much shorter stipe.
