Araceae
Anthurium pendens Croat
SUMMARY
Pendent epiphyte; stems ca. 10 cm long, 1-2.5 cm diam.; internodes to 2 cm long, shorter near apex; leaf scars 1.2 cm wide, often obscured by persistent cataphyll fibers; roots moderately thin, green; cataphylls moderately thick, 7-10 cm long, drying tan, weathering into coarse reticulate fibers. LEAVES pendent: petioles 8-22 cm long, 4-5 mm diam., terete, with reddish brown glands on surface; geniculum 0.5-1 cm long; blades coriaceous, narrowly linear-oblanceolate, long-acuminate at apex, acute at base, 41-75 cm long, 3-12.5 cm wide. usually broadest above middle; both surfaces matte to semiglossy, sparsely and inconspicuously glandular-punctate (conspicuous on drying); lower surface scarcely paler than upper surface; midrib acutely raised above, flat at apex, convexly raised below; primary lateral veins 8-12 per side, departing midrib at 10-20° angle, scarcely visible above or below, prominulous on drying; interprimary veins scarcely visible, drying as prominent as primary lateral veins; collective vein arising from the base, 3-15 mm from margin. INFLORESCENCE spreading to pendent, much shorter than leaves; peduncle terete, 4.5-15 cm long 3.5-5 mm diam., as long as petioles; spathe thin, greenish white, oblong to oblong-lanceolate, 7-7.5 cm long, 1.5-2.5 cm wide, broadest at middle, abruptly acuminate at apex, obtuse to rounded at base, inserted at 35° angle on peduncle, usually withering early and deciduous; spadix pink, turning greenish brown before anthesis, 12-18 cm long, 5-8 mm diam. near base, 4-6 mm diam. near apex, the flowers square to rhombic, 2.9-4 mm wide, 2.9-3.5 mm long, the sides straight to sigmoid parallel to spirals, sigmoid perpendicular to spirals, 5-6 flowers visible in the principal spiral, 7-8 flowers visible in the alternate spiral; tepals semiglossy, the lateral tepals 1.8-2 mm wide, the inner margins broadly rounded; pistils weakly emergent; stigmas ellipsoid 0.4-0.6 mm long, with a small droplet apparent before stamens emerge; stamens emerging in a scattered manner usually beginning at the base but the laterals soon scattered throughout spadix, exserted on thin, clear filaments ca. 2 mm long, retracting to hold anthers close against pistil; anthers white, 0.5-0.6 mm long, 0.6-0.7 mm wide; thecae ovate, moderately divaricate; pollen white. INFRUCTESCENCE pendent; spathe deciduous; spadix to 22 cm long with berries exserted; berries orange (B & K. Yellow 8/2.5), depressed globose, 5 mm long, 5 mm diam.; mesocarp gelatinous, yellow with numerous raphide cells; seeds (1-)2, pale yellow, ovoid, 2-2.7 mm long, 1-1.6 mm wide, with brownish appendage at base.
