Anthurium lactifructum Croat
SUMMARY
Epiphyte; stems less than 10 cm long, ca. 1 cm diam.; leaf scars 8 mm wide; roots moderately thin, green, relatively long; cataphylls 2-3 cm long, drying brown, weathering into fine, persistent fibers. LEAVES spreading; petioles 7-18 cm long, 3.5-4 mm diam., subterete, bluntly and shallowly sulcate; geniculum 1.5-2.2 cm long; blades elliptic to oblong-elliptic, coriaceous, long-acuminate at apex, obtuse to acute at base, 19.5-23.2 cm long, 6.5-9 cm wide, broadest at middle; upper surface matte to semiglossy, eglandular, lower surface semiglossy, dark glandular-punctate; midrib convexly raised at base above, more acute midway, diminishing and sunken at apex, convexly raised below; primary lateral veins 8-12 per side, departing midrib at 40° angle, etched into surface above, flat to prominulous below, straight to collective vein; interprimary veins scarcely visible on both surfaces, drying more or less as prominent as primary lateral veins on lower surface; collective vein arising from the base, etched into surface, equally as prominent as primary lateral veins. INFLORESCENCE spreading, longer than leaves; peduncle terete, 23-41 cm long, 3-4 mm diam., 3-4 times longer than petioles; spathe subcoriaceous, pale green, tinged red-violet, lanceolate, 2.8-4.5 cm long, 0.7-1.7 cm wide, broadest near base, cuspidate at apex, acute and weakly decurrent at base, inserted at ca. 45° angle on peduncle; spadix olive green, becoming lavender at anthesis, tapered toward apex, 4.5-9.5 cm long, 4-5 mm diam. near base, 3-4 mm diam. near apex; flowers 4-lobed, ca. 3.5 mm long, ca. 2.8 mm wide, the sides sigmoid; 5-6 flowers visible in the principal spiral, 7-8 visible in the alternate spiral; tepals matte to semiglossy, weakly punctate, densely and minutely papillate, the lateral tepals 1-1.2 mm wide, the inner margins broadly rounded, tinged purplish; pistils emergent, dark green tinged purplish; stigmas elliptic, ca. 0.4 mm long, more or less obscure, not exserted; lateral stamens emerging throughout, quickly followed by alternates in no apparent pattern; anthers white, 0.3 mm long, 0.6 mm wide, held at side of pistil, retracting after anthesis; thecae oblong, not divaricate; pollen white, quickly dispersing. INFRUCTESCENCE with white, subglobose, berries flattened at apex, sunken medially, ca. 6 mm long. 5-8.3 mm diam.; mesocarp thickly gelatinous; seeds usually 4, greenish white, bright green at apex, ca. 2.3 mm long, 1.4 mm wide, 1 mm thick, surrounded by a transparent sticky sac.
