Wilson, Peter G. & Hyland, B.P.M. (1988) Telopea 3(2): 258. Type: Qld, State Forest Reserve 755, Barong Logging Area, 17 deg 31 S 145 deg 50 E, Gray 400, 23.3.1977; holo: QRS; iso: NSW, UNSW.


Blaze very finely layered.


Numerous small oil dots visible with a lens. Leaf blades rather large, about 15-24 x 6-8 cm, petioles short, about 0.5-1 cm long.


Stamens aggregated in long, linear bundles which are completely free from one another.


Capsules not woody, almost papery. Cotyledons in the embryo are separate, but each cotyledon is reflexed from the top of the petiole and then folded back on itself and crumpled and folded.


Cotyledons about 20-25 mm wide, truncate at the apex with about 5-7 veins radiating from the petiole. At the tenth leaf stage: leaf blade obovate, apex acuminate, base cordate; terminal bud, petiole and stem densely clothed in reddish brown hairs. Seed germination time 9 to 27 days.
