Anthurium lucens Standl.

Epiphyte or terrestrial; stems to 20 cm long, ca. 4.5 cm diam.; internodes and leaf scars obscured by roots and cataphylls; roots dark brown, medium thick, descending; cataphylls subcoriaceous, 6.5-7.5 cm long, heavily tinged red-violet, the apex acuminate with subapical apiculum 2-3 mm long, drying brown (B & K Yellow 4/7.5), weathering to persistent reticulate fibers, the apex remaining ± intact. LEAVES with petioles erect to spreading, (12)26-72 cm long, 0.6-1 cm diam., subtrrete; geniculum 2.5-3.5 cm long, sometimes faintly tinged red-violet; blades narrowly ovate to oblong-ovate or ovate-triangular, moderately thick, gradually acuminate at apex, deeply lobed at base, 30-46 cm long, 18-24 cm wide, broadest at the base or just below point of petiole attachment; the anterior lobe 22-32 cm long, the margins usually convex, sometimes ± straight; posterior lobes 10-16 cm long, the sinus spathulate to hippocrepiform, obtuse to rounded, or sometimes acute at apex; both surfaces semiglossy, the lower surface punctate; the midrib acutely to convexly raised above, convexly raised below; basal veins 5-6 pairs, the first and second free, the remaining coalesced 2-2.5 cm; posterior rib naked one half to one third its length, usually with inner margin turned up; primary lateral veins 2-7 per side, departing midrib at 55°-60° angle, straight or weakly curving to collective vein, sunken above, raised below; lesser veins scarcely visible above, visible and ± flat below; collective vein arising from the first basal vein, in larger blades from fourth or sometimes fifth basal veins, sunken above, raised below, 6-1 5 mm from the margin. INFLORESCENCE usually held erect, arching or pendent in larger plants, shorter than or equalling petioles; peduncle 33-75 cm long, 5-8 mm diam., terete, sometimes tinged red-violet; spathe moderately thin, green heavily tinged with red-violet, lanceolate, 4-8.5 cm long, 1.4-1.7 cm wide, narrowly acuminate at apex, rounded at base, inserted at 45° angle on peduncle; spadix deep violet-purple, 10.5-13 cm long, 9-10 mm diam. at base, 3-3.5 mm diam. at apex; flowers rhombic to weakly 4-lobed, 3-3.2 mm long, 2.6-3 mm wide, the sides straight to gradually or jaggedly sigmoid and somewhat obscure; 6-7 flowers visible in the principal spiral, 8-9 flowers visible in the alternate spiral; tepals matte to weakly glossy, weakly punctate, minutely papillate, with scattered droplets, lateral tepals 1.5- 1.6mm wide, the inner margin broadly rounded; pistils weakly raised, green, sometimes purplish; stigma linear, ca. 0.6 mm long, opening as stamens emerge: stamens emerging from the base in a moderately rapid sequence, the laterals first, soon followed by alternates, the leading stamens several spirals ahead of third or fourth stamens; anthers bright yellow, held at the edge of tepals, ca. 0.6 mm long, ca. 0.3 mm wide; thecae ovate, widely divaricate; pollen pale yellow. INFRUCTESCENCE pendent; the spathe usually deciduous; berries bright red, obovoid to oblong-ellipsoid, usually developing only in basal one quarter to one third, round to truncate at apex, 8-18 mm long, 6.5-18.5 mm diam.; mesocarp juicy, clear, with raphide cells; seeds 1-2, greenish white, oblong-elliptic, slightly flattened, 4-5 mm long, 2.5-4 mm wide, 1.8-2.1 mm thick, obliquely concave at apex.
