Cataphylls, 4-6 produced before the first true leaves or reduced leaves. First true leaves narrowly elliptic, apex apiculate, base obtuse. Stipules about 0.7 mm long, purplish. At the tenth leaf stage: leaf blade narrowly elliptical, apex acute with a thickened point, base obtuse. Midrib and main lateral veins slightly raised on the upper surface. Stipules narrowly lanceolate, about 0.8 mm long. Seed germination time 18 days.
This species has been used as drought fodder and is highly regarded in this capacity. However, the high levels of tannin have caused problems in sheep under experimental conditions. Everist (1974).
Aborigines of the Broome district in Western Australia used the bark medicinally. Cribb (1981).
