Anthurium kamemotoanum Croat

Epiphyte or terrestrial; stem less than 10 cm long, 2-3 cm diam.; roots and leaf scars usually obscure, sometimes green to violet purple; cataphylls moderately thick, 9-17 cm long, sometimes tinged reddish, acute at apex with a minute subapical apiculum, drying reddish brown (B & K Yellow-red 3/10), persisting intact. LEAVES erect-spreading; petioles terete, 32-55(-68) cm long, 4-8 cm diam.; geniculum 3-6.5 cm long, weakly and narrowly sulcate; blades coriaceous, broadly ovate, weakly bullate, abruptly acuminate at apex, deeply lobed at base, 15-37 cm long, 11-28 cm wide, broadest at point of petiole attachment; anterior lobe 10-26 cm long, the margins broadly rounded; posterior lobes 6-14 cm long (from apex of sinus to outermost point); sinus hippocrepiform to obovate, rounded at apex; upper surface semiglossy, lower surface slightly glossier, somewhat paler; midrib convexly raised above, flat to scarcely sunken near apex, acutely raised below; basal veins 4-5 pairs, the first free, those remaining coalesced to 4.5 cm, paler than surface, raised above and below; posterior rib naked, weakly upturned on outer margin; primary lateral veins 3-5 per side, departing midrib at 50° angle, weakly arching to collective vein, weakly sunken above, raised below; interprimary veins visible, flat; lesser veins conspicuous on drying; collective vein arising from the first basal vein, loop-connecting the primary lateral veins, weakly sunken above, scarcely raised below, 3-13 mm from the margin. INFLORESCENCE erect, shorter than leaves; peduncle 4-11.5 cm long, 4-8 mm diam., ca. one-third as long as petioles; spathe cupulate, ovate elliptic, violet purple to deep red-violet (B & K Red-purple 2/10) tinged with green, glossy on both surfaces, held parallel to and cupped around spadix, curving forward with the acumen directed downward, 6.5-8 cm long, 4-5 cm wide, broadest at about the middle, apiculate at apex, rounded to obtuse at base, inserted at 45° angle on peduncle; spadix sessile, deep red-violet (B & K Red-purple 3/5-3/10), 3-6 cm long, 0.8-1.4 cm diam. midway; flowers rhombic to 4-lobed, ca. 1.5 mm long, ca. 2 mm wide, the sides straight to gradually sigmoid or obtusely angular, 8-9 flowers visible in the principal spiral, 10-12 flowers visible in the alternate spiral; tepals glossy, minutely and densely punctate, lateral tepals 1-1.3 mm wide, the inner margin rounded, turned up against pistil; pistil emergent, white, conspicuously raised before stamens emerge; stigmas linear, ca. 0.3 mm long, not conspicuously open before stamens emerge; stamens emerging sporadically throughout spadix, beginning near middle, exserted on translucent filament, 0.2-0.5 mm long, 0.3-0.4 mm wide, retracting to hold anthers at edge of tepals; anthers creamy white, 0.2-0.5 mm long, 0.4-0.6 mm wide; thecae ovoid, slightly divaricate; pollen creamy white. INFRUCTESCENCE not seen.
