Common names
Glycine, Perennial soybean, Soya, Tinaroo glycine, Tropical legume.
A climbing plant with twining or scrambling stems up to 4.5 m long. Its stems, leaves and fruit vary from being relatively hairless to having a dense covering of rusty velvet hairs. Its alternately arranged leaves have three oval leaflets (1-10 cm long and 0.6-7 cm wide). Its small white to mauve pea-shaped flowers (about 1 cm long) are borne in elongated clusters. Its elongated pods (1.5-3.5 cm long) are turned downwards and turn dark brown or blackish when mature.
Impact
Impact
Glycine (Neonotonia wightii) is regarded as an environmental weed in Queensland and northern New South Wales. It is also seen as a potential environmental weed or "sleeper weed" in other parts of northern Australia. This species can infest extensive areas of open land and rainforest margins where it smothers grasses and other understorey vegetation, and sometimes even shrubs and smaller trees. It reduces the amount of light reaching these plants, eventually even killing them, and prevents the regeneration of native species. Its growth is most prolific in tropical and sub-tropical climates where the annual rainfall is between 750-1500 mm.Glycine (Neonotonia wightii) is currently of most concern in south-eastern Queensland, and during a recent study it was ranked among the top 20 most invasive environmental weeds in this region. It appears on numerous local environmental weed lists in south-eastern Queensland (i.e. in Ipswich City, Gold Coast City, Maroochy Shire, Beaudesert Shire, Cooloola Shire and Redland Shire) and is regarded as a threat to ecosystem integrity in conservation areas in Springbrook, on the Gold Coast hinterland.Glycine (Neonotonia wightii) is also listed as an environmental weed in the Townsville City Council region and as an undesirable plant in the Wet Tropics World Heritage Area in northern Queensland. In New South Wales, glycine (Neonotonia wightii) is sporadically naturalised in coastal districts, mainly north from the Bellingen area.
