''Syngonium'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 is a genus of flowering plants in the family Araceae, native to tropical rain forests in southern Mexico, the West Indies, Central and South America.〔(Kew World Checklist of Selected Plant Families )〕 They are woody vines growing to heights of 10–20 m or more in trees. They have leaves that change shape according to the plant's stage of growth, and adult leaf forms are often much more lobed than the juvenile forms usually seen on small house plants. ==Cultivation== ''Syngonium'' species are often grown as house plants, usually only in the juvenile foliage stages. ''Syngonium podophyllum'' is the most commonly cultivated species, and is often referred to simply as ''Syngonium.'' For successful growth, a winter minimum temperature 16 °C to 18 °C (60 to 65°F) must be maintained, rising to 20 °C to 30 °C (68 to 86°F) during the growing season. They require high humidity, including misting the leaves regularly, and good light, but not direct sunlight; they will tolerate low light levels. Water freely from spring to autumn, sparingly in winter. Feed regularly in spring and summer. If juvenile foliage is preferred, cut off all the climbing stems that develop — the plant will remain bushy, rather than climb, and the leaves will be more arrow-shaped. Repot every second spring. Propagation is by cuttings or air layering. ;Species〔 #''Syngonium angustatum'' Schott - Mexico, Central America, Colombia; naturalized in Bahamas, Netherlands Antilles, Bismarck Archipelago #''Syngonium armigerum'' (Standl. & L.O.Williams) Croat - Costa Rica #''Syngonium atrovirens'' G.S.Bunting - Venezuela, Ecuador, Bolivia #''Syngonium auritum'' (L.)
