Anthurium longipes Matuda, Bol. Soc. Bot. Mexico 14: 23. 1952, non N. E. Brown, 1882. TYPE: Belize, Gentle 2624A (MICH).
Epiphyte, usually erect; roots white; stems 1.5-3 cm long, 7-10 mm diam.; internodes short; cataphylls membranaceous, 2-9.5 cm long, drying reddish or brown, persisting intact, ultimately deciduous.

LEAVES ± erect; petioles 1-20 cm long, ca. 3 mm diam., subterete flattened adaxially; the geniculum ca. 5 mm long; blades moderately thin, oblanceolate, 11-32 cm long, 3-8.5 cm wide, acuminate at apex, gradually tapered to long-cuneate at base; the upper surface matte to semiglossy; the midrib prominently raised almost to apex above, raised below; primary lateral veins numerous, nearly obscure; collective vein arising from base, 4-7 mm from margin.

INFLORESCENCE ± erect; peduncles 13-40 cm long, 1-3 mm diam., longer than petioles; spathe membranaceous, red-violet, lanceolate to oblong-elliptic or ovate-elliptic, 1.3-2.5 cm long, 3-7 mm wide, abruptly acuminate at apex, rounded al base; spadix sessile, purplish-brown, 0.6-6 cm long, 2-4 mm diam. midway; flowers 4-lobed, 5-5.6 mm long, 3.8-4.3 mm wide, the sides jaggedly sigmoid; 2-3 flowers visible in the principal spiral, 3-4 flowers visible in alternate spiral; tepals matte to semiglossy, punctate and minutely papillate; pistils weakly emergent, the apex ± flat; stigma exserted, butlonlike, 0.8-0.9 mm wide; stamens emerging in scattered manner; anthers cream, ca. 0.7 mm long, inclined inward over pistil; thecae ovoid, slightly divaricate; pollen white.

INFRUCTESCENCE pendent; peduncle to 60 cm long; spadix to 10 cm long, 1.5 cm diam.; berries bright red, ± globose, slightly longer than broad, 6-8 mm long; me-1 socarpgelatinous, ± translucent, lacking raphide cells, seeds 2, cylindroid, rounded on both ends, ca. 4 mm long, 1.6-1.8 mm diam., with an oblique depression at one end and the other end greenish, sticky gelatinous appendages at both ends. Fig. 77.

The species is found from Guatemala and Belize to the Guianas, southern Brazil and Peru. It is also known in the West Indies from Trinidad and Hispanola. In Costa Rica and Panama, the species is known only from topical moist forest. Anthurium gracile has a large root system that may sometimes become infested with black, stinging ants. It is distinguished by its thin, ob-lanceolate, epunctate leaves, persistent, intact cataphylls, the relatively few-flowered spadix, the whitish roots, and the bright red, globose berries. Anthurium gracile has been confused with A. friedrichsthalii, which differs in having coriaceous, broadly linear leaves, conspicuously punctate on the lower surface, cataphylls that soon weather to persistent fibers, flowers more numerous on the spadix, and berries that are pale yellow-orange, broader than long, and truncate at the apex. Anthurium gracile is also confused with A. bakeri Hook. f., which has punctate leaves with a collective vein that is sunken and more conspicuous than the primary lateral veins. Anthurium gracile is the only described species of section Leptanthurium and is either an extremely variable species or comprised of some additional undescribed sibling species in the Andes of South America (Croat, 1976).
