Araceae
Anthurium coclense Croat
SUMMARY
Usually epiphytic, frequently terrestrial, weakly rooted, 0.5-1.5 m tall; stem elongate, 30-75 cm long, 6-25 mm diam., dark olive green, minutely fissured, turning grayish green; internodes 1-5 cm long; roots few at each node, scaly; cataphylls moderately thin, 6-15 cm long, apiculate at apex, drying yellowish (B & K Yellow 9/2.5), remaining intact or weathering and soon deciduous. LEAVES with petioles (3-)5-57 cm long, 4-9 mm diam., terete to oval, flattened to bluntly sulcate near apex; geniculum 1.5-4 cm long, shaped like the petiole with sharper edges; blades oblong-oblanceolate to elliptic or ovate-elliptic, moderately thin, gradually long-acuminate at apex to abruptly acuminate (the acumen flat, acicular at apex, sometimes downturned), obtuse to narrowly rounded or weakly lobed at base, (18-)28-51 cm long, (3-) 10-26 cm wide, broadest above the middle, the larger blades sometimes noticeably inequilateral with one side to 3 cm narrower than the other; both surfaces semiglossy; midrib obtuse at base above, becoming more acute, diminishing and sunken at apex, paler than surface, sharply raised below, paler than surface; primary lateral veins 6-16 per side, departing midrib at 40-50° angle, straight to arcuate-ascending to collective vein, sunken or weakly raised in valleys above, raised below; interprimary veins few, mostly continuous to the collective vein, sunken above, raised below; collective vein arising from one of the lowermost primary lateral veins, sometimes higher, mostly 3-10 mm from margin. INFLORESCENCE spreading-erect, much shorter than leaves; peduncle 3-35(-50) cm long, 2.5-5 mm diam., subquadrangular, striate, flat to rounded adaxially, the ridges closer and more prominent abaxially, one-fourth to one-half as long as petioles; spathe subcoriaceous, green (B & K Green 7/2.5 to Yellow-green 5/5) at anthesis, both spathe and peduncle sometimes heavily tinged with purple, usually reflexed, narrowly lanceolate to ovate-oblong, 1.5-7 cm long, 0.9-2.5 cm wide, broadest slightly below the middle, abruptly acuminate at apex, rounded at base, inserted at 45° angle on peduncle; stipe to 5 mm long; spadix green to dark green (B & K Yellow-green 5/7.5 to Green 5/5) at anthesis, 2-10.5 cm long, 3-7 mm diam. at base, 2-6 mm diam. at apex, flowers 4-lobed, 2-2.4 mm long, 2.4-2.8 mm wide, the sides jaggedly sigmoid, ca. 10 flowers visible in the principal spiral, ca. 7 flowers visible in the alternate spiral; tepals semiglossy, minutely papillate, darker along the outer margins, weakly punctate or epunctate, with scattered droplets, the lateral tepals 1-1.3 mm wide, the inner margins turned up against the pistil, the outer margin 3- or 4-sided; pistil emergent ca. 0.5 mm before anthesis; stigma round, minutely brush-like, with a minute droplet briefly apparent several days before first stamens emerge; stamens emerging one at a time in a scattered pattern beginning near the base, exserted 0.7-0.8 mm above the tepals; filaments fleshy, transparent, the exposed part longer than the anther, narrowly acute; anthers held erect, 0.4-0.5 mm long, 0.4-0.6 mm wide, pale yellow, widely spaced; thecae scarcely divaricate, oblong-elliptic, opening flat; pollen pale yellow (B & K Yellow 9/5) fading white. INFRUCTESCENCE spreading; spathe persisting, to 8 cm long; spadix to 15 cm long, 2 cm diam.; berries ovoid, acute at apex, reddish becoming dark purple-violet, to 7.5 mm long, 5 mm wide; seeds 2, ovoid-ellipsoid, brown (B & K Yellow 4/2.5), weakly flattened, 3.2-3.8 mm long, 2.2-2.5 mm wide, 1.3-1.5 mm thick.
