Anthurium bradeanum Croat & Grayum

Epiphytic; stem very short, 0.5-1.5 cm diam.; roots moderately dense, descending, green, pubescent, moderately slender and elongate, tapered, 2- -4 mm diam.; cataphylls subcoriaceous, lanceolate, 6-9 cm long, acuminate at apex, light green, drying tan (B & K red 9/10), persisting semi-intact, eventually as linear fibers. LEAVES erect-spreading to spreading; petioles 6-32(40) cm long, 5-7 mm diam., ± quadrangular, occasionally D-shaped, flattened to rounded adaxially, the margins sharply raised but not winged, sharply 2-3-ribbed abaxially (sometimes rounded), the surface pale-speckled; geniculum paler and thicker than petiole, becoming fissured transversely with age, 0.8-2.5 cm long; blades subcoriaceous, elliptic to oblanceolate-elliptic to obovate-elliptic, less than 5 x longer than wide, long-acuminate at apex (the acumen apiculate), acute to abruptly attenuate at base, (20)25- 60 cm long, 8.5-21 cm wide, broadest at or above the middle, the margins weakly undulate, both surfaces glossy to semiglossy, medium green above, paler below, drying green, semiglossy to matte; midrib flat at base, becoming convexly raised toward the apex, pale-speckled, paler than surface above, sharply 2-ribbed and higher than broad at base, becoming convexly raised toward the apex, paler than surface below; primary lateral veins (5)10-15 per side, departing midrib at 30-40° angle, 2 straight to the collective vein or weakly arcuate-ascending, moderately sunken, becoming weakly sunken toward the margin above, prominently and convexly raised below, paler than surface above and below; tertiary veins weakly visible above, slightly darker than surface below; collective vein arising from near the base or about the middle of the blade, sunken above, raised below, less prominent than primary lateral veins, 1-3 mm from margin. INFLORESCENCES erect-spreading to spreading, usually shorter than leaves; peduncle 21-58 cm long, equalling or 2-3 x longer than petioles, several-angled to subterete with prominent sharp rib abaxially, conspicuously pale-speckled; spathe boat-shaped, about as long as spadix and hooded over it (directed at ca. 180° angle to peduncle), coriaceous, dark green, somewhat discolored along margins, ovate, cucullate, 2.5-6(9) cm long, 2.1-4 cm wide, inserted at 50-70' angle on peduncle, abruptly to gradually acuminate at apex, rounded to truncate at base, decurrent on petiole; spadix deflexed, pale yellow-green to lemon-yellow to creamy-white, (occasionally brownish), sessile, clavate, 1.9-5 cm long, 8-10 mm diam., directed at ca. 90° angle from peduncle; flowers 4-lobed, 1.6- 2.2 mm long, 2-2.5 mm wide, the sides jaggedly sigmoid; 16-20 flowers visible in principal spiral, 13-16 in alternate spiral; tepals matte, conspicuously papillate; lateral tepals 0.6-0.9 mm wide, the inner margins straight to convex and turned up against pistil; pistils emergent to 0.5 mm, white to pale greenish white; stigma 0.2 mm long, brushlike, droplets appearing 2-3 days before stamens emerge, persisting for 2 weeks; stamens emerging in a complete sequence, emerging well above tepals then retracting; lateral stamens soon followed by 3rd and 4th stamens, arranged in tight cluster above pistil; filaments whitish, exserted, 0.3- 1 mm long, 0.2-0.3 mm wide; anthers pale yellow, 0.3- 0.4 mm long, 0.5-0.6 mm wide; thecae ellipsoid; pollen pale yellow fading to white, sweet-scented. INFRUCTESCENCE spadix 5-11 cm long; berries greenish yellow to white (also reported as reddish), obovoid, sharply pointed at apex, 4-4.3 mm long, 2.5 mm diam.; seeds 2 per berry, yellowish brown, oblong-ovoid, flattened, 3.2-3.5 mm long, 1.5-1.9 mm diam., 1.1-1.2 mm thick.
