Anthurium cabuyalense Croat & J. Rodr.

Epiphyte; internodes short, 3 cm diam; cataphylls persisting as reddish brown fibers. Leaves spreading-pendent; petioles subterete, obscurely sulcate adaxially, 30–38 cm long, ca. 5 mm diam., firm and flexible; blades oblong, 72–80 cm long, 9–10 cm wide, 7.6–8 times longer than wide, moderately coriaceous, moderately bicolorous, dark green and weakly glossy and somewhat velvety above, medium glossy and weakly glossy below; the surface somewhat undulate, glandular-punctate both above and below, more sparsely so above; midrib convex and paler on both surfaces; primary lateral veins up to 30, flat and only weakly visible, drying weakly raised, scarcely more conspicuous than the interprimary veins; interprimary veins several between each primary lateral vein; tertiary veins obscure; collective veins arising from the lower 1/3 of the blade, 1–6 mm from the margin, weakly sunken above, flat and darker than the surface below, more conspicuous than the primary lateral drying weakly raised on both surfaces. Inflorescences spreading-pendent; peduncle 32 cm long, tinged purplish; spathe green, linear-lanceolate, 10.5 cm long, 11 mm wide, abruptly acuminate at apex, inserted at ca 45 degree angle, spreading at about a 90 degree angle to the peduncle; the margins rolled under along their entire length, meeting acutely at base, weakly decurrent; spadix subsessile, dark green, directed at a 105 degree angle; stipe 1–2 mm in back, 6 mm long in the front; flowers rhombic, 2.6–3 mm long, 1.8–2 mm wide, 6–7 visible per spiral; lateral tepals 1.8–2 mm wide, the inner margin straight to broadly convex; stamens emerging at the surface of the tepals; anthers broadly ovate, 0.4 mm wide. Infructescence not seen.

Anthurium cabuyalense is known only from the type locality in premontane wet forest at 700 m elevation. It is distinguished by its long petiolate spreading﷓pendent leaves with subvelvety oblong blades and long petiolate dark green inflorescence. The species is similar to A. pallidiflorum at the ENDESA reserve but that species differs in having blades which are velvety on the upper surface, rounded at the base and they are not glandular-punctate on either surface. Anthurium cabuyalense is also very similar to another undescribed member of sect. Porphyrochitonium from the Río Nangaritza valley in Zamora-Chinchipe Province. It also has elongate blades and long petioles but it differs in having blades only 5.5 times longer than wide rather than over 8 times longer than wide.

Anthurium cabuyalense is a species of plant in the family Araceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
