INFLORESCENCES 4-6 per axil; peduncle 7 cm long, 4 mm diam., green, semiglossy, drying blackish; spathe 4.5 cm long, tube 6 x 7 mm diam., pale green throughout inside, drying blackish brown; spadix 4.1 cm long, 5 mm diam. at middle, 4 mm diam. at apex; male portion length 1.4 cm, female portion length 1.6 cm; pistillate portion pale green; pistils 4-locular, 1 mm long, 0.7-1.0 mm diam.; style broadly rounded on the margins; stigma weakly stalked, 0.4-0.5 mm diam., the stigmatic papillae erect to spreading; ovules basal, 1 per locule, contained within a translucent envelope that fills the entire locule, this 0.5-0.6 mm long, 0.3-0.4 mm diam., the ovule proper filling most of the translucent envelope, and about 1/3 of its total length is funicle.
Philodendron edwinii is endemic to Colombia, known only from the type locality in Caquetá Department in the region of Florencia on the eastern slopes of the Cordillera Orientale at 900 m in a Tropical wet forest life zone.
