Distribution : Connu seulement de la localité type, la rivière Mataroni où il a été collecté plusieurs fois. Egalement largement diffusé en culture par les amateurs d'Araceae, tant dans des collections privées (y compris en Guyane française) que dans des jardins botaniques publics (comme par ex. à Brest, Nancy, Utrecht, Miami, Rio de Janeiro [Sitio Burle Marx]).

Etymologie : "The presumed hybrid is named in honor of Mr. Joep Moonen who discovered it in 1990 and has had it in cultivation for many years. Moonen, a professional photographer and naturalist, is one of the best authorities on the Araceae of the Guianas, having studied and traveled widely in the region. He is the owner of Emerald Jungle Village, tourist facility in French Guiana. Joep is also a Volunteer Research Associate of the Missouri Botanical Garden’s Aroid Research Program"

Taxonomie : Hybride naturel supposé entre Philodendron bipennifolium Schott 1855 et P. pedatum (Hook.) Kunth 1841.
"The plant is believed to be a natural hybrid between Philodendron pedatum (Hook.) Kunth and P. bipennifolium Schott, both of which occur in the area. They are both members of subgenus Philodendron section Schizophyllum (Schott) Engl., a small group of species with pinnately lobed leaf blades. Philodendron × joepii is very rare in nature. Plants in culture in the wet tropics regularly flower but there is no evidence that mature and viable fruits are developed. This adds to the theory that it is a natural hybrid. Since the presumed hybrid is a part of the Amazonian flora and has been collected several times, it is deemed worthy of a name."
