Leguminosae
Common names
Coolan, cooba, umung, black sally wattle, willow, black mattle.
Characteristics
Fairly large tree; grows mainly on river and creek channels
and in levee soils; bark dark grey, almost black, furrowed; wood dark but
fairly soft; leaves grey-green, often slightly succulent, with a prominent
midrib; flowers pale yellow, in balls; pods thick and fleshy, froth if
shaken in water; seeds black with a prominent red aril. It is abundant
in the 375- to 625-mm rainfall belt, but extends almost to the coast. Leaves
are eaten to some extent, but are not widely used. They contain large amounts
of tannin and have been suspected of poisoning hungry cattle. The pods
are rich in saponin (Everist, 1969).
