- General Description
- Terrestrial; internodes short, drying 0.6-1 cm diam.; cataphylls 7-9.5 cm long, drying dark reddish brown, lanceolate, persisting at upper internodes, weathering to tan longitudinal fibers near apex, and a reticulum of fibers near base. LEAVES: Petioles 22.5- 38.4 cm long, averaging 30.4 cm, drying 3-4 mm diam., sulcate adaxially, darkened or grayish brown, sometimes yellow-tinged; geniculum slightly thicker than petiole, sometimes blackened, 1-2 cm long, drying 2-4 mm wide; blades ovate to ovate-elliptic, rarely weakly falcate, sometimes markedly arched along midrib, sometimes inequilateral (one side up to 1 cm wider than the other), gradually long-acuminate at apex (acumen 2-4 cm long), base slightly attenuate, 27.5-36 cm long (averaging 31.2 cm), 7.5-10.8 cm wide, 3-4.4 times longer than wide, blade 0.8-1.1 times longer than petiole, revolute at margins, drying eglandular, brownish green above, densely but somewhat faintly glandular-punctate, semi-glossy, grayish brown below; midrib broadly convex, drying 2-4 mm diam., sometimes slightly wider towards base, concolorous or slightly darker above, convex to narrowly convex, drying 2-3 mm wide, sometimes slightly wider towards base, concolorous or slightly paler below; primary lateral veins 12-17 per side, 1-3 cm apart, departing midrib at a 55-65° angle, sometimes arising at an acute angle and then spreading, somewhat loop-connected, concolorous above, concolorous and prominent below; collective veins usually arising from base, more prominent than primary lateral veins, 2-7 mm from margin. INFLORESCENCE with peduncle 25-34 cm long (averaging 30 cm), drying 2-3 mm diam., 0.8- 1.1 times the length of the petiole, medium to light brown; spathe spreading to reflexed-spreading, green to green-red, oblong, 3.7- 5.5 cm long, abruptly acuminate; spadix green, cylindroid, sometimes very slightly tapered, erect, sometimes with a slight curve toward the spathe, 3.9-7 cm long, drying 3-4 mm diam. Flowers 2.7-2.8 × 2.1-2.8 mm, 3- 4 visible per spiral; lateral tepals 1.2 mm wide, outer margins 2-sided.
- Diagnostic
- Characterized by ovately shaped blades with a very long acumen. Anthurium atamainii is similar to A. yamaykatense Croat, but that species has very prominently loop-connected collective veins, longer cataphylls, and a more elliptic blade.
- Habitat
- Premontane wet forest (P-wf) and Tropical moist forest (T-mf) life zones (Holdridge 1971).
- Distribution
- Known from northern Perú.
