Anthurium chiapasense subsp. tlaxiacense (Matuda) Croat

Epiphytic or epipetric; stems to 6 cm long, 2 cm diam.; internodes and leaf scars obscured by cataphylls; roots moderately thick, green; cataphylls subcoriaceous, 6.7-8 cm long, acute at apex (apiculate to 1 mm), drying brown (B & K Yellow 4/5), weathering into coarse fibers, persisting around stem. LEAVES erect-spreading; petioles 37-64 cm long, 6-8 mm diam., ± terete; geniculum 2.5-4 cm long, sometimes weakly sul-cate; blades subcoriaceous, narrowly triangular, 35-56 cm long, 13-30 cm wide, acuminate at apex (apiculate 5 mm), deeply lobed at base, broadest at base; anterior lobe 28-45 cm long, the margins round to convex; posterior lobes 9-12 cm long, directed upward; sinus hippocrepi-form, acute at apex; upper surface matte to semiglossy, lower surface matte, glandular-punctate; midrib flat to convexly raised above, weakly sunken at apex, prominently raised below; basal veins 4-5 pairs, the third to fifth coalesced 1.5 cm, flat to weakly sunken above, raised below; posterior rib naked, turned up; primary lateral veins 5-6 per side, departing midrib at 20°-25° angle, sunken above, raised below, straight to collective vein; lesser veins obscure above, prominulous below; submarginal collective vein usually arising from the uppermost basal vein, 7-9 mm from the margin, sunken above, raised below. INFLORESCENCE spreading-pendent, equalling leaves; peduncle 53-57 cm long, 5-7 mm diam., terete; spathe subcoriaceous, yellow-green (B & K Yellow-green 7/5), lanceolate, 6-7 cm long, 1.5-1.7 cm wide, margins thin, transparent, soon withering, inserted at 40° angle on peduncle; spadix dark yellow-green to gray-green, heavily tinged red-violet at outer margins ofte-pals, 5.5-8.5 cm long, 6-9 mm diam. at base, 3-5 mm diam. at apex; the flowers 4-lobed, 2.3-3 mm long, 2.4-2.8 mm wide, the sides sigmoid; 6-8 flowers visible in the principal spiral, 6-7 flowers visible in the alternate spiral; tepals matte, weakly punctate, densely papillate, lateral tepals 1.3-1.6 mm wide, the inner margin convex; pistil raised, green, glossy; stigma elliptic, 0.4-0.5 mm long, deep purple with large globose droplet ca. 1 week before stamens emerge; stamens emerging from base, lateral stamens emerging throughout, alternates following within a few days, exserted well over pistil on fleshy, red-violet tinged filaments, retracting when anthers open; filaments ca. 5 mm long, ca. 6 mm wide, anthers pale yellow, ca. 0.6 mm long, 1.9 mm wide; the-cae oblong, scarcely divaricate; pollen yellow fading cream. INFRUCTESCENCE arching-pendent; spathe usually absent; spadix 10-12(20) cm long, 1.5-3.5 cm diam. (5-6 cm diam. with berries fully emerged); berries ± obovoid to oblong-elliptic, rounded at apex, bright red (B & K Red 4/5); mesocarp translucent, juicy, with numerous raphide cells; seeds 1-2, green, streaked with purple, weakly flattened, 4.5-5 mm long, ca. 3 mm wide, 1 mm thick, enveloped in a transparent, amber, gelatinous sack.
