Anthurium nizandense Matuda

Usually terrestrial or epilithic; leaf scars 0.7- 1.2 cm high, 1.3 cm wide; roots moderately numerous, descending, greenish to tan, smooth to somewhat pubescent, moderately elongate, tapered; cataphylls subcoriaceous, 3-7 cm long, rounded and minutely apiculate at apex, drying dark brown, persisting semi-intact, eventually as a reticulum of fibers. LEAVES erect-spreading; petioles 6-24 cm long, (3)5-6 mm diam., quadrangular to D-shaped to subterete, flattened to broadly and sharply sulcate adaxially, the margins sharply raised, rounded abaxially, the surface pale-speckled, sometimes tinged with red-violet; geniculum slightly paler and thicker than petiole, 1-1.5 cm long; blades subcoriaceous, obovate-elliptic to elliptic, acute to abruptly acuminate at apex (the acumen apiculate), rounded to acute or attenuate at base, 25-57 cm long, 10.7-30 cm wide, broadest at or above the middle, the margins weakly undulate; upper surface matte to semiglossy, medium green, lower surface matte, paler below; both surfaces with short, linear raphide cells and convexly raised epidermal cells, drying brown to greenish brown; midrib acutely to convexly raised above, more prominently so below; primary lateral veins 6-11 per side, departing midrib at 50-80° angle, straight to weakly arcuate-ascending to the collective vein, raised above and below, darker than surface below; tertiary veins obscure above, weakly visible below; collective vein arising from about the middle of the blade or near the apex, 3-9 mm from margin. INFLORESCENCES erect, equalling or longer than leaves; peduncle 31-60 cm long, 5- 8 mm diam., 1.8-2.7 x as long as petiole, terete; spathe reflexed, subcoriaceous, green, ovate-lanceolate, 8-9.5 cm long, 2.5-3 cm wide, broadest near the base, inserted at 45° angle on peduncle, acute at apex, apparently obtuse at base; spadix pale green becoming reddish brown, somewhat tapered, 12-14 cm long, 9-11 mm diam. near base, 4 mm diam. near apex; flowers rhombic, 1.8-2.5 mm long, 2.8-3 mm wide, the sides sigmoid; 7- 9 flowers visible in principal spiral, 5-6 in alternate spiral; lateral tepals 1.5 mm wide, the inner margins broadly convex or weakly concave; pistils not emergent; stigma broadly ellipsoid; stamens emerging rapidly in a complete sequence, emerging shortly above the tepals, arranged in a circle around the pistil; anthers ca. 0.4 mm long, 0.6 mm wide; thecae ellipsoid, weakly divaricate. INFRUCTESCENCE pendent; spathe withered; spadix 6.5 cm long, 1.5 cm diam.; berries greenish white, ovoid, 8 mm long; mesocarp transparent, juicy, pulpy; seeds l(2) per berry, pale yellow (B & K yellow 9/2.5), broadly obovoid, 5.2-5.4 mm long, 4.5-4.7 mm diam., 3.4-4 mm thick, with a minute, translucent appendage, ± gnarled at apex on side, tinged with brown, enveloped by gelatinous substance.
