Scientific Name
Syngonium neglectum Schott
Synonyms
Syngonium podophyllum Schott (misapplied)
Family
Araceae
Common Names
arrowhead vine, goosefoot, syngonium
Origin
Native to Mexico, where it is widespread.
Naturalised Distribution
Naturalised in south-eastern Queensland, and possibly more widely naturalised throughout the coastal districts of eastern Queensland.
Notes
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 neglectum has been mistaken for Syngonium podophyllum in the past, it may also be much more widespread in other parts of Queensland.
