Philodendron ilsemanii

Philodendron ilsemanii is a name published in the Gardeners' Chronicle in 1908 for a plant in cultivation. Several checklists treat it as a misapplied name for Philodendron ornatum, a large climbing philodendron of northern and western South America and Brazil. With no wild records under this name, care is based on P. ornatum and on warm, wet-forest climbers generally.
