Anthurium sanctifidense Croat

Terrestrial, rarely epiphytic; stem 1.5-2 cm diam., to 30 cm long or more; leaf scars often hidden by persisting cataphylls; roots stout, green to grayish; cataphylls moderately thick, 10-20 cm long, cuspidate-acuminate at apex, drying reddish brown, persisting intact. LEAVES usually erect; petioles 33-50 cm long, 4-11 mm diam., subterete, shallowly and bluntly sulcate; geniculum 2.5-3 cm long, shaped like petiole, sometimes greatly thickened where it meets the blade: blades broadly ovate, lobed at base, abruptly acuminate at apex (the acumen slightly twisted, downturned), 21-57 cm long, 16-46 cm wide, broadest at point of petiole attachment, anterior lobe 16-3 5 cm long, the margins broadly rounded; basal lobes 5-14 cm long, directed basally or somewhat outward, the sinus parabolic to broadly triangular, obtuse to rounded at apex; upper surface matte to semiglossy, drying dark brown with sparse, pale, linear raphide cells, lower surface moderately paler with many pale, weakly raised, round glands (not dark punctations); midrib obtusely raised above and below, diminished and sunken at apex above, basal veins 5 or 6 pairs, 2 or 3 of them coalesced 1.5-3 cm, raised at base, sunken near margin above, raised below, the posterior rib straight to slightly curved, naked, the outer margin rolled upward; primary lateral veins 5-7 per side, departing midrib at ca. 45° angle, more or less straight to collective vein, raised or sunken above, raised below; lesser veins less conspicuous; submarginal collective vein arising from the uppermost basal vein or one of the primary lateral veins, 5-7 mm from the margin, weakly sunken above, weakly raised below. INFLORESCENCE stiffly erect; peduncle 7-36 cm long, 5-8 mm diam., subterete, one-sixth to one-third as long as petioles; spathe pale green to greenish white, medium thick, ovate to lanceolate or oblong-elliptic, 5.5-15 cm long, 2.8-3.4cm wide, broadest just above peduncle, cuspidate-acuminate at apex (the acumen 1.5-3 cm long), obtuse to weakly subcordate at base, reflexed spreading decurrent ca. 6 mm, the margins turned down near the base; stipe 2-7 mm long in back, green; spadix greenish white (B & K Yellow-green 9/7.5), 6.7-15 cm long, 9-11 mm diam. near base, 5-9 mm diam. near apex; flowers sub-rhombic to 4-lobed, 3-3.3 mm long, 3.3-3.6 mm wide, the sides jaggedly sigmoid to almost straight, the sides parallel to the spiral, straighter than those perpendicular to the spiral, 7-17 flowers visible in the principal spiral, 5-11 flowers visible in the alternate spiral; tepals glossy, smooth, the lateral tepals 1.4-1.8 mm wide, the inner margin very broadly rounded to almost straight, turned up against pistil; pistils flat to moderately exserted, pale green to white, becoming purplish, exserted 0.3-0.7 mm at anthesis; stigma tufted, raised, colorless, extending ca. 0.3 mm above the pistil; stamens emerging, scattered from the middle and soon progressing toward both ends, held over the pistil; anthers creamy white, 0.5-0.6 mm long, 0.8-0.9 mm wide, obscuring pistil when completed; thecae narrowly ovoid, slightly divaricate; pollen white. INFRUCTESCENCE with spathe persistent, the spadix purplish; berries obovoid, ca. 8 mm long, 5.5 mm wide, rounded at apex, violet purple, sometimes whitish toward the base; pericarp thin sometimes with moderately conspicuous linear raphide cells; seeds 2, pale green (?), encased in a mucilaginous, transparent sack, to ca. 6.5 mm long, moderately flattened, oblong-ellipsoid, emarginate at apex, 5-6 mm long, 2.7-4 mm wide.
