CATE Araceae, 17 Dec 2011.

Local Aguaruna name: eep.
Apparently endemic to Perú in Amazonas and Loreto Departments.
Premontane wet forest transition to Tropical (P-wf/T) and Tropical moist forest (T-mf) life zones.
Recognized by short internodes, persistent pale cataphyll fibers, moderately long petioles, narrowly oblanceolate brownish yellow-drying blades with widely spaced primary lateral veins and by a long, slightly tapered spadix and small, globose, lavender berries. Anthurium kayapii is similar to A. apanui, but differs in having narrower, more oblanceolate, darker yellow-brown leaf blades (5.5-7.8 times longer than wide versus 4.6-4.7 times longer than wide in A. apanui) with 8-11 primary lateral veins (versus 5 for A. apanui), and longer cataphylls (8-11 cm long versus less than 6 cm for A. apanui).
General Description
Epiphytic; internodes short, 1-1.5 cm diam.; cataphylls 7-10.3 cm long, persisting as fine fibers in a semi-intact network or moderately disorganized. LEAVES: Petioles subterete, 19 cm long, drying 3-4 mm diam.; blades narrowly oblanceolate, 36.8-49 × 5.1-8 cm, 4.3-7.8 times longer than wide, 1.8-3.1 times longer than petioles, gradually long-acuminate at apex, narrowly acute at base, subcoriaceous, drying weakly glossy to semiglossy, dark yellow-brown to gray-brown above, slightly paler and yellow-brown below, margin curled under; midrib drying convex to +/- acute and finely and irregularly several-ridged and concolorous above, narrowly raised and finely many-ridged, slightly darker than surface below; primary lateral veins 9-12 per side, arising at 25-40° angle, moderately more conspicuous than the interprimary veins and about as prominent as the collective veins; collective veins arising from the base and mostly 2-5 mm from the margins; tertiary veins moderately prominent on the lower surface. INFLORESCENCE erect, about as long as or shorter than the leaves; peduncle 23-44 cm long; drying 2-3 mm in diam., dark yellow-brown; spathe 7.5-10 cm × 4-8 mm, oblong-ligulate, green to white, narrowly acuminate, (soon falling on most herbarium material); spadix green to pink, narrowly linear-tapered, 9.5-18.5 cm × 2-4 mm, drying dark brown. Flowers 1.5-1.6 mm long and wide, 5-6 visible per spiral, sides straight parallel to the spirals, smoothly sigmoid perpendicular to the spirals; lateral tepals 0.8 mm wide, broadly rounded on inner margin, 2-sided on outer margin; INFRUCTESCENCE: berries lavender (B&K purple 2.5/6), +/- globose, 3-4 mm diam., drying dark yellow-brown with subglobular, white cellular inclusions in pericarp; seeds 3 or more per berry, ca. 1.4 mm long.
