Hyland, B.P.M. (1989) Australian Systematic Botany 2: 236. Type: B. Hyland 7755: State Forest Reserve 143, South Mary Logging Area, 10.x.1974 (QRS, holotypus).

Stem

Blaze odour usually noticeable, somewhat pine-like (Pinus spp.). A thin cream or pale brown layer normally visible under the subrhytidome layer before the first section of the outer blaze.

Leaves

Twigs terete or fluted, clothed in straight, appressed, white or pale brown hairs when young but +/- glabrous at maturity. Leaf blades about 5-8.7 x 1.5-2.6 cm, green or slightly glaucous on the underside, clothed in straight, appressed, pale brown hairs when young, sometimes becoming almost glabrous when older. Midrib depressed or flush with the upper surface. Petioles flat or channelled on the upper surface. Oil dots visible with a lens.

Flowers

Flowers opening quite widely, the tepals eventually becoming reflexed at or after anthesis. Tepals about 1.6-2.4 mm long. Staminal glands absent. Staminodes usually present, three, not differentiated into a head and stalk.

Fruit

Fruits ellipsoid to globular but more commonly depressed globular, usually also laterally compressed, about 43-55 x 40-61 x 35-55 mm on the longer and shorter axes. Seed about 32-42 x 25-42 x 29-48 mm. Cotyledons cream or yellowish.

Seedlings

First pair of leaves narrowly elliptic, about 80-105 x 20-30 mm. At the tenth leaf stage: leaves elliptic, glabrous on the upper surface, undersurface sometimes slightly glaucous; oil dots small, numerous, visible with a lens. Seed germination time 33 to 182 days.

Distribution and Ecology

Endemic to NEQ, restricted to the Mt Spurgeon-Mt Lewis area. Altitudinal range from 600-1300 m. Grows in well developed upland and mountain rain forest on soils derived from granite.

Natural History & Notes

This species grows large enough to produce millable logs but is not utilized. Wood specific gravity 0.80. Hyland (1989).
