Native to South America (i.e. Venezuela, Brazil, Bolivia, Peru, northern Argentina, Paraguay and Uruguay).
Naturalised in many parts of eastern Australia (i.e. in south-eastern and northern Queensland and in the coastal districts of northern and central New South Wales).
Silverleaf desmodium (Desmodium uncinatum) was introduced as a fodder crop and has now become a weed of creekbanks (i.e. riparian areas), roadsides, fencelines, forest margins, disturbed sites, waste areas and plantation crops (e.g. sugarcane). It is regarded as an environmental weed in south-eastern Queensland, where it is listed among the top 100 most invasive plants species, and on the New South Wales North Coast.
Silverleaf desmodium (Desmodium uncinatum) spreads into forest margins and along creeks where it trails over shrubs and groundcovers, but it does not climb into trees. It has also been reported to ensnare and kill native wildlife (e.g. frogs, birds, lizards and microbats) that easily become stuck to its stems and fruit.
