Common name



Dead bark layered. Inner and outer blazes very fibrous.


Leaves phyllodineous. Leaf blades about 9-17 x 0.6-16 cm. Veins longitudinal, parallel, not anastomosing, generally 2-3 more prominent than the rest. A small gland normally visible on the upper side of the leaf blade-petiole junction.


Spikes about 3-8 cm long, on glabrous peduncles about 5-10 mm long, in axillary pairs. Calyx cylindrical, glabrous, about 0.8-1 mm long, apex sinuate. Corolla about 1.8-2.5 mm long, glabrous, lobes strongly reflexed, about as long as the tube. Stamens about 2.5-3.5 mm long. Ovary densely pubescent.


Pod +/- flat, sometimes raised over the seeds, coiled, up to 10 x 0.3-0.5 cm. Seeds (colour unknown) longitudinally or slightly obliquely oriented in the pod, about 3.5-5 x 2.5-3.5 mm. Funicle (colour unknown) folded many times beneath the seed to form an aril-like structure nearly as long as the seed.
