Anthurium cotobrusii Croat & R.A.Baker

Terrestrial or often epilithic; stem usually less than 15 cm long, 1-3 cm diam.; roots descending, greenish or grayish brown, smooth to weakly pubescent, moderately thick and elongate, to 6 mm diam.; cataphylls subcoriaceous, lanceolate, 4.5-11 cm long, acute at apex, green, sometimes tinged with purplish, drying light brown, persisting semi-intact, eventually as fine linear fibers. LEAVES erect to spreading; petioles 15-65 cm long, 4-7 mm diam., ± terete, weakly sulcate to flattened adaxially, rounded abaxially; geniculum thicker than petiole, (1)3-5 cm long; blades subcoriaceous, narrowly ovate to triangular, long-acuminate at apex (the acumen downturned, weakly apiculate), shallowly and broadly cordate at base, 16-65 cm long, 9.5-33 cm wide, broadest at base, the margins weakly undulate; anterior lobe (13)18-30(37) cm long, the posterior lobes (5)7-13(15) cm long, directed upward and slightly inward, narrowly rounded at apex; sinus arcuate to broadly parabolic when flattened, hippocrepiform when not, (4)7-9 cm deep; upper surface semiglossy, dark to medium green, lower surface glossy to semiglossy, conspicuously paler, both drying matte to weakly glossy, yellowish green; midrib obtusely raised at base, becoming more sharply raised and then sunken at apex above, obtusely to convexly raised and more prominent below; basal veins 3-5 pairs, all free to base or 3rd-4th coalesced 4-6 cm, weakly raised to flat above, weakly raised and darker than surface below; posterior rib naked, gradually curved to almost straight, turned up on outer margin; primary lateral veins 4-8 per side, departing midrib at 50-60° angle, broadly arcuate, sharply to weakly raised or weakly sunken above, weakly raised to flat and darker than surface below; interprimary veins obscure above, flat and darker than surface below; tertiary veins obscure above, weakly visible below; reticulate veins obscure above and below; collective vein arising from one of the uppermost basal veins or one of the lowermost primary lateral veins, sunken above, slightly raised and darker than surface below, almost as prominent as primary lateral veins, 3-8 mm from margin. INFLORESCENCE erect-spreading; peduncle (4)20-60 cm long, 4-10 mm diam., (0.7)l-1.7 x as long as petiole, terete; spathe reflexed, subcoriaceous, green to pale green or green with purplish veins or heavily suffused with purple on inner surface, sometimes tinged with purple only at base, ovate to narrowly ovate, weakly boat-shaped to flat, (2.5)5-15 cm long, (1.7)2.7-4.5 cm wide, inserted at 60-90° angle on peduncle, acuminate at apex (the acumen inrolled), acute to rounded or shallowly cordate at base; stipe 1-2 cm long in front, 2-6 mm long in back; spadix green to brownish green to dark purple- violet, cylindroid to weakly tapered, erect to curved, (2.5)5-25 cm long, 7-15 mm diam. near base, 3-7 mm diam. near apex; flowers ± 4-lobed, 3.5-5 mm long, 3.5-4 mm wide; 3-6 flowers visible in principal spiral, 7-10 in alternate spiral; tepals sparsely punctate, more densely so near the margins, semiglossy to matte, the inner margins broadly convex; pistils emergent, matte, green; stigma linear, purple-violet or green, ca. 0.6 mm long, with brush like papillae; droplets appearing 1-3 weeks before stamens emerge, sometimes persisting when 1st and 2nd stamens are opening; stamens weakly exserted, in a tight cluster above pistil; filaments whitish, soon retracting, 0.4 mm long, 1 mm wide; anthers orange to yellowish, 0.6-0.9 mm long, 1 mm wide; pollen pale orange fading to white, yeasty-scented. INFRUCTESCENCE erect spreading; spathe persisting; spadix 12-18 cm long, 1.5-2 cm diam.; berries pale orange (B & K yellow-red 8/7.5), obovoid, darker and rounded at "apex with radial ridges, 12-1 5 mm long, 8-1 1 mm diam.; mesocarp juicy, orange; seeds usually 2 per berry, oblong-ellipsoid, 6.5-7.5 mm long, 2.5-4 mm diam., encased in flattened, translucent envelope that projects up to 3 mm beyond the apex of the seed and up to 1 mm beyond the lateral margins.
