INFLORESCENCES 1-6 per axil; peduncle 7-12 cm long, 4-9 mm diam. at middle, white on lower 1/2, pale green above, coarsely whitish streaked onto base of tube; spathe 12-17 cm long, 1.5-2 cm diam. on tube, erect, coriaceous, semiglossy, glabrous; spathe tube deep burgundy within, dark purple outside, 5-7 cm long, 2-3.5 cm diam.; spathe blade broadly lanceolate, broadly acuminate at apex, white inside, at least at tip, often tinged reddish violet on base of blade pale yellow-green outside, at least at tip, often tinged dark purple at base; spadix 10-14 cm long; pistillate portion cylindroid, 2.1-3.1 cm long, 11-14 mm diam.; staminate portion tapered, 6-8 cm long, 10-12 mm diam. at base, 6-8 mm diam. at apex, moderately tapered at apex; sterile staminate portion broadest at base, narrowest near apex, 2.5-3.5 cm long, 12-14 mm diam. at base, 8-11 mm diam. near apex; staminate flowers 1.1-1.3 mm long, 1.0-1.2 mm wide, irregularly shaped; sterile staminate flowers 2.7-3.2 mm long, 0.9-1.6 mm wide, irregularly shaped; pistils 3.0-3.2 mm long, 1.1-1.3 mm diam.; stigma 1.1-1.3 mm diam.; locules 5 per ovary; ovules 0.1-0.2 mm long, numerous in each locule.


Philodendron verrucapetiolum ranges from Colombia (Narino) to adjacent Ecuador (Carchi), at 1,780-2,010 m in Premontane wetforest. At La Planada, this species is apparently relatively frequent and widespread, having been collected near the summit of the hill above La Posada in the small patch of forest between the two pastured areas, along the trail to El Hondon beginning at Quebrade EI Tejon, in virgin cloud forest along Sendero La Vieja, and along the trail to the summit of the hill behind the Centro de Cientificos.
