Epiphytic or terrestrial, 56-120 cm tall; stems usually short, stout, 2-3 cm diam., cataphylls turning brown, remaining intact, eventually splitting; petioles 10-70 cm long, (5-)8-9 mm diam., broadly sulcate above sheath, more deeply sulcate near apex with acute margins, rounded abaxially; blades ovate to narrowly ovate, coriaceous, semicrect or spreading from petioles, truncate to subcordate or cordate at base, 15-50 cm long, 12.5-37 cm wide. Inflorescence erect to spreading; peduncle (23-)30-88 cm long, 5-10 mm diam., terete, frequently mottled with purple, two-thirds to three times longer than petioles; spathe coriaceous, green tinged with purple, narrowly ovate-oblong to oblong-lanceolate, (5-)8-14 cm long, (1-)2.8-3.9 cm wide, stipe 5-25 mm long; spadix violet purple, (6-) 12-2 5 cm long, (6-)8-13 mm diam. at base; immature berries white, oblong-linear, square in cross-section, ca. 10 mm long; mature berries purple-violet, 1.3-1.5 cm long, ovoid and prominently beaked, the basal portion 6.5-8.5 mm diam., round in cross-section, the beak reddish violet. See Croat (1983: 310) for a more complete description.

The species ranges from Costa Rica to Colombia (mountains of northwest Choco adjacent to Panama) at elevations of 350 to 1,800 m. It occurs only along the central cordillera. In Panama, the species has been collected in premontane wet, tropical wet, and lower montane wet forest from Cerro Colorado in Chiriquí Province to the Cerro Jefe region in Panama Province and then appears again only near the Colombian border in Darien. Anthurium lentii is in section Digitinervium and can be recognized by its thick, distinctively bicolorous, heavily punctate, truncate to cordate leaf blades with several heavy, prominently ascending basal veins. Another distinctive feature includes the prominently exserted pistils.
