Anthurium collinsii Croat

Terrestrial; stems elongate, 10 cm or more long; leaf scars obscured by persistent cataphylls, cataphylls 2.5-3 cm long, drying medium brown, weathering into fine fibers. LEAVES erect-spreading; petioles 18-21 cm long, 2-3 mm diam., terete; blades ovate, moderately thin; long-acuminate at apex, rounded to weakly subcordate at base, 13-15 cm long, 8-9 cm wide; both surfaces semiglossy, glandular-punctate; midrib raised above and below (dry); primary lateral veins 10-12 per side, departing midrib at 45-50° angle, prominulous above and below (dry); interprimary veins visible above, obscure below (dry); collective vein arising from near the base, 6-7 mm from margin, raised above and below, loop-connecting primary lateral veins, forming an acute angle with margin near apex. INFLORESCENCE shorter than leaves; peduncle 14-16 cm long, 1-2 cm diam., shorter than petioles; spathe reddish, thin, lanceolate, ca. 2 cm long, 6-8 mm wide, acuminate at apex, acute at base; spadix reddish, 3-4 cm long, ca. 3 mm diam. at base, 2 mm diam. at apex, the sides sigmoid, 3-4 flowers visible in the principal spiral, 4-5 flowers visible in the alternate spiral; tepals semiglossy, lateral tepals 0.4-0.6 mm wide, the inner margins convex; pistils emergent; stigmas exserted, brush-like; stamens exposed just above tepals; anthers persisting after anthesis, ca. 0.2 mm long, ca. 0.5 mm wide; thecae ovoid, slightly divaricate. INFRUCTESCENCE with berries (immature) globose, purplish in upper half, greenish in lower half; mesocarp with numerous punctiform, whitish raphide cells; seeds (immature) 4, oblong, light brown, 2 mm long, 1 mm wide, conspicuously flattened, slightly tapered toward apex (point of attachment), rounded at base, enveloped in a flattened, transparent sack that is longer and broader than the seed itself.
