Anthurium affine Schott

Terrestrial; stem short, 1.5-4 cm diam.; roots moderately numerous, descending to spreading, greenish, smooth to weakly pubescent, thick, moderately elongate, 3-8 mm diam.; cataphylls subcoriaceous, broadly lanceolate, 6-20 cm long, actuminate to narrowly rounded and prominently apiculate at apex, light green, drying brown, persisting semi-intact, eventually dilacerating into coarse linear fibers. LEAVES erect to spreading; petioles 5-28 cm long, 7-16 mm diam., U-shaped to quadrangular, shallowly to prominently sulcate, sometimes with a medial rib adaxially, prominently and sharply raised marginally, usually (1)3-5-ribbed, or sometimes rounded abaxially; geniculum thicker and slightly paler than petiole, becoming fissured transversely with age, 1-2.5 cm long; blades moderately coriaceous, obovate to oblanceolate to ± elliptic, obtuse to short-acuminate or rounded at apex (the acumen apiculate), acute to obtuse to rounded or shallowly cordate at base, 33-95 cm long, 10.5-32 cm wide, broadest at or above the middle, the margins markedly undulate; upper surface matte to semiglossy, dark green, lower surface semiglossy to glossy, paler, both surfaces drying olive-green to yellow-green; midrib flat and 1-ribbed at base, becoming obtusely angled toward the apex above, slightly paler than surface, prominently thicker than broad and 2-3-ribbed at base below, becoming convexly raised toward the apex, paler than surface; primary lateral veins 7-14 per side, departing midrib at 40-60° angle, slightly arcuate to the margin, prominently and convexly raised above and below; interprimary veins absent; tertiary veins obscure to weakly sunken above, slightly raised and darker than surface below; reticulate veins not visible ro prominulous when dried, collective vein arising from near the apex or absent, less prominent than primary lateral veins when present. INFLORESCENCES erect, somewhat shorter than the longest leaves; peduncle 31-78 cm long, 4-15 mm diam., 2-9 x as long as petiole, green or green-tinged with purple at apex, subterete; spathe reflexed to recurled, moderately thick, purple to green tinged with purple, ovate to broadly lanceolate, (3.5)5-10 cm long, 1,7-7.5 cm wide, acuminate at apex, acute and usually decurrent to 1-3(6) cm at base; stipe 0.5-5 cm long, 6-18 mm diam., pale green to purple; spadix olive-green to yellowish, cylindroid to clavate, subsessile to long-stipitate, erect, straight, 4.5-17 cm long, 5-15mm diam. near base, 6-10 mm diam. near apex, broadest near the middle or near the apex; flowers ± square, 1.6-2.2 mm in both directions, the sides straight to sigmoid; 7-14 flowers visible in principal spiral, 4-10 in alternate spiral; tepals slightly roughened, pale-punctulate (when dried); lateral tepals 0.7-1 mm wide, the outer margins 2-sided, the inner margins convex to rounded; stamens emerging in a regular sequence from the base, semi-erect in a tight cluster above the pistil, arching over and obscuring it; anthers 0.5-0.7 mm long, 0.7-0.8 mm wide; thecae somewhat divaricate; pollen creamy. INFRUCTESCENCE erect; spadix ca. 2.5 cm diam. (not including exserted berries); berries red to rich purple-maroon or purple-maroon at apex becoming red below, whitish toward the base, obovoid to oblong-ellipsoid, truncate at apex, 7-13 mm long, 407 mm diam.; seeds oblanceolate, 5-8 mm long, 2-3 mm diam.
