Syngonium angustatum Schott
Syngonium podophyllum Schott (misapplied)
arrowhead vine, fivefingers, goosefoot, syngonium
Native to Mexico and Central America (i.e. Belize, Costa Rica, Guatemala, Honduras and Nicaragua).
Naturalised in south-eastern Queensland, and possibly more widely naturalised throughout the coastal districts of eastern Queensland.
Also naturalised overseas in south-eastern USA (i.e. Florida) and on some Pacific islands.
Syngoniums (Syngonium spp.) are regarded as environmental weeds in Queensland, where they invade urban bushland, riparian vegetation, coastal environs, open woodlands and closed forests. Until recently Syngonium podophyllum was thought to be the only problem species in Queensland, but there are actually three closely related species present in this state (i.e. Syngonium podophyllum, Syngonium neglectum and Syngonium angustatum ).
Field observations indicate that all three species are equally invasive and common in bushland in south-eastern Queensland. Since Syngonium angustatum has been mistaken for Syngonium podophyllum in the past, it may also be much more widespread in other parts of Queensland.
