Roundleaf Cassia: Wynn
(Chamaecrista rotundifolia)

Roundleaf cassia is a short-lived perennial, nitrogen-fixing shrub, growing up to 1 m tall. It is adapted to sandy soils and semi-arid environments. It provides good quality forage for livestock and is used as a legume in mixed grass/legume pasture systems.

Primarily used as a pasture legume but it has potential use as a forage crop. It has been successfully introduced as a self-seeding annual into drier regions of northern Queensland, Australia that receive only about 600 mm of annual rainfall.
