Anthurium campii Croat

Terrestrial or epiphytic; stem short, 3.5-5.5 cm diam.; roots dense, upper ones ascending, lower ones descending, whitish to grayish, woolly-pubescent, moderately tapered, ca. 3-12 cm long, 4- 5 mm diam.; cataphylls thickly coriaceous, lanceolate, 22-40 cm long, obtuse at apex, medium green, drying medium brown, persisting intact or semi-intact, eventually as coarse linear fibers. LEAVES erect-spreading; petioles (3)17-23 cm long, (6)lO-15 mm diam., thicker than broad to D-shaped to trapezoidal or C-shaped, sharply to broadly V-sulcate adaxially with the margins raised, sharply 2-9-ribbed abaxially; geniculum conspicuously thicker than petiole, 1-2.5 cm long; sheath 9-13 cm long; blades coriaceous to subcoriaceous, broadly oblanceolate to oblong-elliptic, rounded to obtuse or sometimes acute at apex, acute at base, (46)90- 145 cm long, 23-37 cm wide, broadest above the middle, the margins slightly undulate; upper surface matte to semiglossy, dark green, lower surface semiglossy to glossy, paler; midrib broadly convex at base, becoming flat-raised toward the middle and narrowly convex at the apex above, trapezoidal and 3-ribbed at base, becoming acutely angled and then convex toward the apex below; primary lateral veins 14-40 per side, departing midrib at 50-70° angle, straight or slightly arcuate to the collective vein, convexly raised above, less conspicuously so below; interprimary veins sometimes present, inconspicuous to almost as conspicuous as primary lateral veins; tertiary veins darker than surface and flat below, moderately indistinct; reticulate veins prominulous above and below (or not visible) on drying; collective vein arising from or near the base, equally as prominent as primary lateral veins, 1-13 mm from margin. INFLORESCENCES erect; peduncle (36)50-85 cm long, (3)5-6 mm diam., 2.5-3(6) x as long as petiole, terete to bluntly or sharply multiribbed; spathe spreading, with the margins curled under, subcoriaceous, medium green, becoming yellowish, oblong-lanceolate, (7)13-20 cm long, 1.3-2 cm wide, broadest near the base, inserted at 30° angle on peduncle, shortly acuminate at apex, acute at base; spadix medium green, sessile or shortly stipitate, cylindroid to long-tapered, erect to curved, (8)12-23 cm long, 5-9 mm diam. near base, 3-4 mm diam. near apex; flowers rhombic, 1.7-2.6 mm long, 1.1-1.9 mm wide, the sides straight to smoothly sigmoid; 6- 13 flowers visible in principal spiral, 5-7 in alternate spiral; tepals matte; lateral tepals 1-1.3 mm wide, the inner margins rounded, erose, the outer margins 2-sided; pistils weakly emergent; stigma ellipsoid to broadly ellipsoid; anthers tan, 0.5-0.6 mm long, 0.6-0.7 mm wide; thecae oblong, not divaricate; pollen yellow fading to white. INFRUCTESCENCE (immature): spreading(?); spathe reflexed and persistent, green; spadix 22-30 cm long, 1.4 cm diam.; berries light purple; pericarp with raphide cells; seeds unknown.
