Indigofera pratensis

Scientific NameIndigofera pratensis
CategoriesNitrogen FixerShrub
Common Name(s)Forest Indigo
FamilyFabaceae, Subfamily Faboideae

Description

"Perennial, ascending up to ca 60cm tall,with pale sparse to dense appressed hairs. Leaflets 13-21,..." (Stanley, T.D. and Ross, E.M., 1983)

Notes

Indigofera pratensis has exellent potential for rehabilitation works. Like other Indigofera species, its seed is forgiving to work with being easy to spread and having long viability. The distribution of the taxon covers large areas where rehabilitation works could take place and this includes Central Queensland mining areas and busy coastal areas. The nitrogen fixing properties of the plant will also attract interest where the building of soil fertility is an aim. Productivity of wild stands is a limitation for seed collectors and cultivation may be required to aid commercialisation of the seed. Notable wild cropping is likely when considerable early season rain occurs after winter burning of forest areas. Indigofera pratensis appears to often be confused with Tephrosia species such as Tephrosia brachyodon, Tephrosia rufula and others. Indigofera species have pods which are terete, meaning they are roughly circular in cross-section or cylindrical. Taxa from the Tephrosia genus have flattened pods. Seed morphology is also distinct.

Historical Notes

Distribution

Indigofera pratensis is found in coastal and inland areas of Queensland. It may occur as far as 600km west of the coastline in southern areas however it also occurs right across northern Queensland, northern parts of the Northern Territory and Western Australia.
