Gymnostoma australianum L.A.S.Johnson
Oak grain in the wood.
What appear to be needle-like leaves are really twigs and the true leaves (in whorls of four) are just visible to the naked eye when the needles are broken at a joint. Oak grain in the twigs.
Cones about 7-10 x 8-10 mm, with a broad bract beneath each pair of bracteoles. Samaras about 7-8 mm long.
Cotyledons reniform to orbicular, +/- 3-5 mm diam., 3 or 4 veins radiate from the petiole. First leaves minute, triangular, opposite or in a whorl of four. At the tenth leaf stage: leaves minute, triangular, clasping the stem, in whorls of four.
Distribution and Ecology
Endemic to NEQ, restricted to Thornton Peak and its environs. Altitudinal range from near sea level to 1350 m. Grows in association with rain forest but usually in situations where full rain forest development is arrested, e.g. along watercourses subject to flood damage or on mountain tops.
Shrub (woody or herbaceous, 1-6 m tall)
