Anthurium papillilaminum Croat

Terrestrial; stems ca. 10 cm long, ca. 3 cm diam.; leaf scars 2.5 cm wide; roots green, medium thick, descending; cataphylls 4-6 cm long, drying brown (B & K Yellow 4/2.5), persisting intact at apex, splitting at base. LEAVES with petioles erect-spreading, sometimes the blade held parallel to petiole; petioles 16.5-34 cm long, 4-6 mm diam., subterete, sometimes very shallowly sulcate, dark olive green, sometimes tinged reddish to red-violet; geniculum 1-1.5 cm long, pale green at base of blade or sometimes tinged red-violet; blades oblong-ovate to narrowly ovate, moderately thin, acuminate at apex (the acumen flat), lobed at base, 25-43 cm long, 11.5-26.5 cm wide; anterior lobe 19-30.4 cm long, the margins rounded; posterior lobes 6.5-13.5 cm long; sinus hippocrepiform to nearly triangular, rounded to acute at apex; both surfaces matte, densely papillate; upper surface deep green, velvety, lower surface pale olive green; midrib narrowly and acutely raised above, diminished and flat toward apex, narrowly and acutely raised below; basal veins 4-5 pairs, the first and second free to the base, those remaining coalesced 0.5-1 cm, paler than surface and raised above, flat to weakly raised below, sometimes tinged reddish; posterior ribs naked, the outer margin turned up; primary lateral veins 3-4 per side, departing midrib at 35-45° angle; usually straight to collective vein, prominulous above, flat below; interprimary veins scarcely visible above, conspicuous below; collective vein arising from the first basal vein, forming an acute angle with the margin, sunken above, raised below, 1.5-3.5 cm from the margin. INFLORESCENCE erect-spreading, longer than leaves; peduncle 28.5-54 cm long, 3-6 mm diam., terete, heavily tinged red-violet, one and a half to two times longer than the petioles; spathe moderately thin, green tinged with red-violet, lanceolate, 6.3-12 cm long, 0.8-1.8 cm wide, broadest near the base, gradually acuminate at apex, obtuse and unequal at base, inserted at ca. 30° angle on peduncle; stipe 4-14 mm long, faintly tinged red-violet; spadix green (B & K Yellow-green 6/10), tapered toward apex, 3-13.5 cm long, 4.5-9 mm diam. near base, 3-4 mm diam. at apex; flowers sub-4-lobed 2-2.9 mm long, 2.3-3 mm wide, the sides straight to jaggedly sigmoid, 5-6 flowers visible in the principal spiral, 4-8 flowers visible in the alternate spiral; tepals matte to semiglossy, minutely papillate; lateral tepals 0.8-1.5 mm wide, the inner margin obtusely angular to concave; pistils emergent, green; stigma linear-elliptic, brush-like, drying brown; stamens emerging from the base, the laterals emerging nearly to apex before the alternates emerge; anthers cream, held against pistil at edge of tepals, ca. 0.5 mm long, 0.8 mm wide; thecae oblong, not divaricate; pollen cream-colored. INFRUCTESCENCE not seen.
