Anthurium ceronii Croat

Epiphyte; stems pendent, ca. 20 cm long, to 1 cm diam.; internodes 0.5 - 1.5 cm long, 0.4 - 1.8 cm diam.; cataphylls 5 - 8 cm, green, 1-ribbed and acuminate at apex, persisting more or less intact at upper nodes, drying brown into brittle fibers at lower nodes. LEAVES with petioles 3.5 - 18 cm long, spreading-pendent, sheathed to between 1/2 and 3/4 their length; geniculum upturned, thicker and drying darker than petiole; blades oblong-narrow elliptic, (6.2)16 - 20 cm long, 4 - 8 times longer than petiole, 30 - 60 cm long, 2 - 4.5 cm wide, broadest at 2/3 to 3/4 the length from base, moderately coriaceous, narrowly acuminate with acumen 2 - 4 cm, attenuate at base, both surfaces matte, upper surface dark green, drying grayish, lower surface much paler, drying more brownish; midrib convexly raised above, much larger below; primary lateral veins 12 - 18 per side, departing midrib at 35° angle, raised slightly more below than above; interprimary veins only slightly less prominent than primary veins; collective veins arising from the base, with same prominence as primary lateral veins, 2 - 5 mm from margin. INFLORESCENCE spreading, shorter than leaves; peduncle 16 - 25 cm long, 3 mm diam., pale green, quadrangular, the margins winged; spathe spreading, subcoriaceous, yellowish green (B & K yellow green 8/10), linear or narrowly lanceolate, 6 - 10 cm long, 1 - 1.5 cm wide, broadest near base, inserted at a 60° angle on petiole, the apex acuminate with acumen inrolled, 5 mm long, the base margins meeting acutely at 50° angle, stipe 12 - 20 mm long in back; spadix olive-green (B&K yellow 5/5) at anthesis, paler (B&K yellow 7/7.5) prior to anthesis, long ellipsoid, scarcely, bluntly tapered at apex, curved upwards away from spathe, 6 - 13 cm long, 4 mm diam. at base and at middle, 3 mm diam. at apex, turning reddish, producing white berries; flowers slightly rhombic, 2.8 mm long, 2.2 - 2.4 mm wide, 5 in principal spiral, 3 in alternate spiral, the sides nearly straight to slightly sigmoid; tepals matte pre-anthesis, 1.2 mm wide, inner margins rounded, outer margins 2-sided, pistils raised before stamens emerge, green, stigma slitlike, raised, droplets appearing several days before anthesis, 0.5 mm long, slightly papillate; stamens emerge in unusual manner, the alternates preceding laterals by 2 spirals, barely emerging above tepal level, closely circling pistil but not obscuring pistil; anthers white; 0.6 - 0.7 mm long, 0.4 mm wide; thecae 0.2 - 0.3 mm wide; pollen white.
