Rozefelds, A.C. & Pellow, B. (2000) Nordic Journal of Botany 20(4): 435-440. Type: SFR 144, Fantail LA, [Mount Windsor State Forest], 16 14'S 145 5'E, Altitude 960 M, Gray 2668, 8 July 1982.

Lenticels usually quite visible and numerous. Blaze darkens on exposure. Bark or 'gum veins' often visible in transverse sections of the stem.


Leaflet blades about (5-) 8-15 (-22) x 2.5-5 (-11.5) cm. Densely pubescent on veins on undersurface. Stipules large broad and strongly dentate, about 9-11 x 8-11 mm with a conspicuous midrib. Stipules held more or less at right angles to the twig to form a skirt or flange.


Flowers about 6-8 mm diam. Each petal truncate or bilobed at the apex, usually tipped with two glands. Stamens ten, dimorphic, the longer ones alternating with the petals. Disk orange-yellow, quite large and conspicuous.


Fruits with stellate hairs, 3-4 winged, fruits + wings about 20 x 15 mm. Wings conspicuously reticulately veined.


Cotyledons oblong, about 10-14 x 3-6 mm, hairy on the upper surface, stipules 2 and deeply bifid. At the tenth leaf stage: leaf blade obovate, margin serrate; hairy on the upper surface; stipules 2 deeply bifid, gradually becoming 4 in older growth, shortly petiolate, margins serrate; petiole and stem densely hairy. Seed germination time 14 to 25 days.

Distribution and Ecology

Endemic to NEQ and widely distributed throughout the area north from Julatten. Altitudinal range from near sea level to 1100 m. Grows in well developed rain forest on a variety of rock types but tends to be more common along creeks and gullies.
