Acacia albida   (Ana tree)

A tree up to 20 m high with light-brown bark and hairy leaves 5-10 cm long with thorns at the base. Bears leaves only during the dry season. Light-yellow flowering spikes and crescent shaped or circular light-brown pods 10 cm long and 1-2 cm broad. Found chiefly along rivers. Prefers sandy soils. Pods readily eaten by game and stock, and leaves eaten by all farm animals except horses. No recorded indications of poisoning. Highly promising as a forage plant in areas with a prolonged dry season. A full-grown tree able to produce well over 100 kg of pods a year.
