Anthurium ernestii var. ernestii (Araceae)
Epiphytic; stem 6-20 cm long, 1-3 cm diam.; roots dense, green, whitish when dried, velutinous, 2-5 mm diam.; cataphylls subcoriaceous, 2-ribbed, 3-12 cm long, acuminate at apex, drying reddish brown to light brown (B & K yellow-red 4/10), persisting intact, eventually as reticulum of fine, straw-colored fibers with the apex remaining intact. LEAVES erect-spreading; petioles 4-30 cm long, 3- 13 mm diam., D-shaped, sulcate and with a medial rib adaxially, the margins acute, rounded to 1-5- ribbed abaxially; geniculum thicker and paler than petiole, 0.5-2.3 cm long; sheath 1.5-6 cm long; blades subcoriaceous, elliptic to oblanceolate to oblong- oblanceolate, acute to acuminate at apex (the acumen flat), attenuate to obtuse, rarely rounded at base, (25)40-60(131) cm long, (6)7-20(36) cm wide, broadest at or above the middle, the margins broadly undulate, frequently concave in the lower part of the blade; both surfaces matte to semiglossy, generally drying green; midrib broadly and acutely raised at base, becoming flat toward the apex above, acutely raised below with a prominent central ridge at base, becoming slightly convex at apex; primary lateral veins 6-15 per side, departing midrib at 30-70° angle, straight to arcuate-ascending to the margin, prominently raised near the midrib, flat to sunken near the margin above, prominently raised below, drying orangish; tertiary veins prominulous, raised on both surfaces; collective vein arising in the upper ? of the blade, 5-13 mm from margin. INFLORESCENCES erect; peduncle 3-25(45) cm long, 2-6 mm diam., 0.5-3(5.7) x as long as petiole, pale green, terete; spathe erect to reflexed or recurled, subcoriaceous, green to green tinged with red at base (B & K yellow-green 6/7.5), lanceolate to broadly lanceolate, 4-12 cm long, 1-3(4) cm wide, broadest near base or sometimes at or near middle, inserted at 45-80° angle on peduncle, abruptly acuminate to acute at apex, acute at base; spadix pinkish to magenta to purplish or green at anthesis, sessile, rarely stipitate to 0.5-1 cm, cylindroid, slightly tapered, erect, slightly curved, 3-1l(20) cm long, 3-14 mm diam.; flowers 4-lobed, 1-1.9 mm long, 1.4-1.7 mm wide, the sides sigmoid; 5-8(17) flowers visible in principal spiral, 7-1l(16) in alternate spiral; tepals matte, densely papillate; lateral tepals 0.4-1 mm wide, the inner margins straight to convex, the outer margins 2-3-sided; pistils raised, the exposed portion rectangular to squarish, often reddish violet, darker than tepals; stigmas slitlike to ellipsoid, 0.2-0.6 mm long; stamens emerging in a regular sequence, the laterals preceding the alternates by up to 27 spirals, the 3rd stamen preceding the 4th by up to 25 spirals; filaments ca. 0.6 mm long, 0.8 mm wide; anthers purplish or pinkish to pinkish white, 0.2-0.7 mm long, 0.4-0.6 mm wide, inclined over and obscuring the pistil; thecae ellipsoid, not divaricate; pollen pale yellow fading to white. INFRUCTESCENCE spreading; spathe withered; berries red-violet to violet (B & K purple 3/10-4/l0), subglobose to obovoid, rounded at apex, 4-10 mm long, 3-6 mm diam.; seeds 1-2 per berry, obovoid, 2-4 mm long, 1.5-2.5 mm diam., creamy brown, with sticky appendage at apex; mesocarp grayish, juicy, somewhat mealy.
Ranges throughout western Amazonia, from southern Colombia (Putumayo) to Peru (Amazonas, Loreto, San Martín, Huánuco, Pasco, and Madre de Dios), and western Brazil (Acre and Amazonas as far east as the Rio Madeira).
