Anthurium seleri Engl.

Terrestrial; internodes and leaf scars obscured by cataphylls and roots; roots numerous, medium thick, descending; cataphylls subcoriaceous, 6-11 cm long, sometimes faintly tinged reddish at apex, sometimes with long hair-like subapical apiculum, drying reddish brown, splitting at base, remaining intact at apex and persisting. LEAVES with petioles erect to spreading, (7)14-48 cm long, 4-6 mm diam., sharply and shallowly sulcate; geniculum 1.4-1.6 cm long; blade moderately thick, narrowly triangular to oblong-lanceolate or oblong-lanceolate with hastate posterior lobes, gradually acuminate at apex, usually broadly lobed, sometimes deeply lobed or ± rounded to truncate at base, (9)24-50 cm long, (5)10-50 cm wide, broadest at base; anterior lobe (8.5)25-41 cm long, margins convex to straight; posterior lobes 6-18 cm long, from sinus to outermost point; the sinus usually parabolic, sometimes arcuate with petiole decurrent, broader than deep, rounded at apex; the upper surface matte to semiglossy, the lower surface matte; midrib bluntly and weakly raised above, convexly raised below; basal veins 2-5 pairs, the second to fifth coalesced to 8 cm; posterior rib straight, naked, turned up on outer margin; primary lateral veins 9-11 per side, departing midrib at 45°-50° angle, usually straight, loop-connecting to collective vein, sunken and nearly obscure above, flat below; collective vein arising from one of the lowermost basal veins, sunken above, flat below, 2-6 mm from margin. INFLORESCENCE erect-spreading, longer than leaves; peduncle 25-50(86) cm long, terete, sometimes faintly tinged with purple; spathe moderately thin, lanceolate, pale green, tinged reddish at base, 5-9 cm long, 0.9-1.5 cm wide, long-acuminate at apex, acute to rounded at base, inserted on peduncle at 50°-70° angle; stipe 4-20 mm long in front, 1-15 mm long in back; spadix green, tinged red-violet along inner margins of tepals, 6-13 cm long, 6-8 mm diam. at base, 2-4 mm diam. at apex; flowers rhombic to sub-4-lobed, 3.5-3.7 mm long, 3-3.5 mm wide, the sides ± straight to gradually sigmoid; 4-5 flowers visible in the principal spiral, 4-10 flowers visible in the alternate spiral; tepals matte, minutely punctate, abundant droplets when stamens begin to emerge, lateral tepals 1.4-1.6 mm wide, the inner margin straight to convex, ± transparent; pistils emergent to 4 mm, white to pale green with minute purple punctations; stigma linear, ca. 0.5 mm long; stamens emerging slowly from the base in a ± complete sequence, lateral stamens first followed by alternates, the basal spirals complete as lateral stamens emerge above middle, exserted on short filaments, ca. 0.2 mm long, soon retracting and held in a circle at edge of pistil; anthers tan, 0.5-1 mm long, 0.7-1.2 mm wide, inclined over pistil; thecae ellipsoid, slightly divaricate; pollen white to pale yellow. INFRUCTESCENCE pendent; berries red, obovoid, 6-7 mm long, 4 mm wide.
