Summary

Philodendron rio-pretense C.A.S.Bat. & M.L.Soares belongs to the subgenus Philodendron. This newly described species is similar to P. carinatum and P. wurdackii but differs from these species primarily due to a combination of the following characteristics: persistence of the prophyll (twisted); stipe short, locules 4 – 7, ovules 1 – 2 and funiculus with trichomes. Notes on the habitat, geographic distribution and conservation status are also provided.
