Byrnes, N.B. (1981) Austrobaileya 1(3): 385. Type: Cook District: S F R 310, Goldsborough L.A., 17 deg 15 S 145 deg 45 E, 18 Jan 1878, B.Hyland 3657RFK; holo: BRI.


Hard, narrow, brittle, orange-brown stripes in the blaze. Sometimes small amounts of clear exudate are produced from the inner blaze, exudate darkens on exposure.


Leaf blades about 3-8.5 x 1-3.5 cm. Small oil dots visible with a lens. Glands normally present on the margin of the leaf blade just above its junction with the petiole (normally 1 or 2 glands on each side).


Flowers about 20 mm long. Stamens ten. Ovary fused to one side of the floral tube. A bilobed gland-like structure also attached to the floral tube opposite the ovary. Ovules about 14-20 in each flower.


Fruits two or 4-winged, wings formed from two bracteoles in the flower. Fruits about 18-25 x 18-25 mm overall, including the wings. Wings papery, venation +/- radiating from the centre.


Cotyledons much wider than long, about 7 x 14 mm, +/- truncate at the apex. Venation obscure but 3 veins usually visible radiating from the base. First pair of leaves small, +/- orbicular. At the tenth leaf stage: young shoots clothed in pale +/- prostrate hairs, leaves +/- lanceolate, apex acute, base attenuate; oil dots small, visible only with a lens. Seed germination time 76 days.
