Cotyledons ovate to orbicular, about 12-17 x 12-18 mm with a few hairs on the upper surface along the venation and margin. Usually one pair of cataphylls produced before the first pair of true leaves. First pair of true leaf blades ovate, much smaller than the cotyledons, each with a spine about 8 mm long in the axil. At the tenth leaf stage: leaf blade ovate, about 3-5 mm long, apex acute, acuminate or shortly aristate, sharp, base rounded, obtuse, glabrous on the upper surface, each leaf with a simple, up to 1 cm long, axillary spine. Petioles and stems densely clothed in short looping or arched hairs. Seed germination time 119 to 144 days.
Although this species is suspected of being poisonous to stock there is little or no evidence to substantiate the claim. Everist (1974).
