Anthurium wendlingeri G. M. Barroso,

Bol. Soc. Venez. Ci. Nat. 26: 151. 1965. TYPE: Costa Rica. Canago: Turones (Pavones), Turrialba, 700 m, Wendlinger s. n. (RB, holotype).

Pendent epiphyte; stems ca. 20 cm long; the internodes 1.5-2 cm long, except near apex; roots moderately thick; cataphylls moderately thick, 5.5-15 cm long, acuminate at apex, drying brown, weathering into coarse persistent, longitudinal fibers.

LEAVES spreading-pendent; petioles terete, (5)8-30 cm long, 2-4 mm diam.; geniculum 1-1.5 cm long; blades oblong, moderately thick, 32-80 cm long, 3-11 cm wide, acuminate at a apex, round to truncate at base; upper surface weakly velvety, obscurely and sparsely glandular-punctate, lower surface semiglossy, sparsely glandular-punctate; midrib convexly raised at base above, more acute toward apex, diminishing and flat at apex, raised at base below, flat from ca. midway to apex; primary lateral veins II-24 per side, departing midrib at 30°-40° angle, raised and nearly obscure above, flat below; lesser veins obscure; collective vein arising from the lowermost primary lateral vein, weakly sunken above, flat to weakly raised below, 5-9 mm from margin.

INFLORESCENCE spreading to pendent, usually shorter than leaves; peduncle 13-42 cm long, 3-7 mm diam.; spathe moderately thin, pale green tinged purplish, ± oblong, 7-11 cm long, 8-13 mm wide, gradually acuminate at apex, inserted at ca. 45° angle on peduncle, withering and curling horizontally or deciduous; spadix pale green to white or grayish-white, straight when young, becoming spiralled in age, 12-80 cm long, 3-5 mm diam. at base, narrowly-tapered to apex; flowers ± 4-lobed, 3-3.1 mm long, 2.4-2.6 mm wide, the sides smoothly sigmoid; 4-5 flowers visible in the principal spiral, ca. 10 flowers visible in the alternate spiral; tepals matte, weakly punctate, minutely papillate, the lateral tepals 1.6-1.7 mm wide, the inner margin broadly rounded; pistils weakly emergent, pale green, glossy; stigmas linear, 0.3 mm long; lateral stamens emerging scattered throughout length of spadix, alternate stamens soon following with no apparent pattern; anthers cream, held at edge of tepals against sides of pistil, ca. 0.7 mm long, ca. 0.6 mm wide; thecae ellipsoid, not divaricate; pollen creamy-white.
INFRUCTESCENCE pendent; berries reddish, ± oblong or globose, ca. 5 mm long, flattened at apex with a central depression. Figs. 220, 226,and 227.

Panamanian plants considered A. wendlingeri range from Veraguas in the west to Code, Panama, and Col—n Provinces on the Atlantic slope and along the Continental Divide in tropical wet forest and premontane rain forest at elevations of 350 to 900 m. Anthurium wendlingeri was described from live material collected in Cartago Province of Costa Rica. The type description reports the inflorescences as being "atropurpureus" and no other flowering material has been seen for Costa Rica. Panamanian collections closely matching this species in vegetative condition, habit and all other aspects consistently have spadices that are white to grayish-while at anthesis. More material must be seen from Costa Rica to determine if those populations really do have purple spadices and to determine if the Panamanian plants arc the same or if they should be considered distinct. One collection from Code (Croat 37329) was reported to have a reddish spadix but it has consistently flowered with a while spadix in cultivation. The species is in section Porphyrochitonium and is distinguished by its coriaceous, oblong, glandular-punctate leaf blades, very elongate, whitish, corkscrew-like spadix and reddish berries. The blades arc weakly velvety and obscurely punctate above and below. It is most easily confused with another Panamanian species, A. pendens Croat (ined.), which occurs in similar habitats in Col—n and Panama Provinces. That species differs, however, in having narrowly oblanceolate blades that are acute at the base and that dry conspicuously blackened, and especially by its slouter, relatively short, greenish-purple to brownish spadix, which never coils. costa rica. hereuia: S of Cariblanco, Croat 35830 (MO).
