Philodendron is a large genus of flowering plants in the Araceae family, consisting of about 900 species according to TROPICOS (a service of the Missouri Botanical Garden). Other sources quote different numbers of species: S.J. Mayo reports about 350-400 formally recognized species, whereas Croat lists about 700. Regardless of number of species, the genus is the second-largest member of the arum family. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo or 'love' and dendron or 'tree'. They are commonly called by their generic name. Philodendron species can be found in many diverse habitats in the tropical Americas and the West Indies. Most occur in humid tropical forests, but can also be found in swamps and on river banks, roadsides and rock outcrops.
