Anthurium hebetatum Croat

Epiphyte; stems 20 cm or more long, 1.5-3 cm diam.; internodes 1-2 cm long; leaf scars 1-1.5 cm wide; roots green to brownish, ca. 5 mm diam., smooth, descending; cataphylls subcoriaceous, brittle, 13-18.5 cm long, tinged violet, the epidermis cracking, acuminate at apex, held around petiole, drying tan, persisting more or less intact, ultimately deciduous. LEAVES spreading to pendent; petioles 10-44 cm long, 7-9 mm diam., weakly flattened to shallowly and sharply sulcate adaxially, sometimes faintly 1-2-ribbed abaxially, the epidermis turning gray to tan and cracking; geniculum 2-4 cm long; blades coriaceous, oblong to oblong-elliptic or oblong-ovate, acuminate at apex, rounded to shallowly lobed at base, (25-)39-85 cm long, (6-)9-18.5 cm wide, broadest near middle or just below; anterior lobe 38-81 cm long, the margins straight to weakly convex; posterior lobes 1-5.5 cm long (from apex of sinus to outermost point); sinus parabolic to hippocrepiform or sometimes spathulate; the surface matte, midrib acutely raised above, diminishing toward apex, convexly raised below; basal veins 3-5 pairs, usually free to the base, flat to prominulous above and below; primary lateral veins 12-20 or more per side, departing midrib at 30-35° angle, weakly sunken above, flat to prominulous below, interprimary veins flat above and below, lesser veins obscure; collective vein arising from the first basal vein, sunken above, prominulous below, 3-5 mm from margin. INFLORESCENCE spreading, shorter than leaves; peduncle 11-32 cm long, 5-9 mm diam., terete, one-third to one-half longer than petioles; spathe subcoriaceous, pale green, tinged red-violet at edges, lanceolate, usually brittle, 5-12.5 cm long, 1.5-2.2 cm wide, broadest at middle or below, acuminate at apex, rounded to acute at base, the margins weakly turned up, thin and cracking; spadix medium green (B & K Yellow-green 6/7.5), slightly tapered toward apex, 6-21.5 cm long, 5-11 mm diam. near base, 4-7 mm diam. near apex; flowers square to 4-lobed, 2.2-3.2 mm long, 2-2.7 mm wide, the sides sigmoid, 7-9 flowers visible in the principal spiral, 5-7 flowers visible in the alternate spiral; tepals semiglossy, minutely papillate, lateral tepals 0.7-1.9 mm wide, the inner margins straight and flat; pistils scarcely emergent, pale greenish white; stigma ca. 0.4 mm long; lateral stamens emerging nearly to apex of spadix before third and fourth stamens emerge; anthers white, 0.4-0.6 mm long, 0.3-0.7 mm wide, held over and covering pistil; thecae ellipsoid, not divaricate, pollen white. INFRUCTESCENCE with obovoid-ellipsoid, purple berries, ca. 6 mm long, 3-3.5 mm wide; mesocarp gelatinous with linear raphide cells; seeds 2, 2.8-3 mm long, ca. 2 mm wide, with minute appendage at apex, longer appendage at base.
