Eucalyptus granitica

Eucalyptus granitica is a tree that typically grows to a height of 20 m (66 ft) and forms a lignotuber. It has hard or soft, dark grey to black ironbark on the trunk and branches. Young plants and coppice regrowth have stems that are more or less square in cross-section and leaves that are more or less sessile, lance-shaped, 60–110 mm (2.4–4.3 in) long and 1–20 mm (0.039–0.787 in) wide. Adult leaves are lance-shaped, more or less the same glossy green on both sides, 70–150 mm (2.8–5.9 in) long and 13–32 mm (0.51–1.26 in) wide on a petiole 10–20 mm (0.39–0.79 in) long. The flower buds are usually arranged in groups of seven on a branched peduncle, 3–11 mm (0.12–0.43 in) long, the individual buds on pedicels 2–4 mm (0.079–0.157 in) long. Mature buds are oval, 4–6 mm (0.16–0.24 in) long and about 3 mm (0.12 in) wide with a conical to rounded operculum. Flowering has mostly been recorded between July and September and the flowers are white. The fruit is a woody cup-shaped or barrel-shaped capsule 4–6 mm (0.16–0.24 in) long and 3–6 mm (0.12–0.24 in) wide with the valves near or below rim level.[2][3]

Eucalyptus granitica was first formally described in 1991 by Ken Hill and Lawrie Johnson from a specimen collected near Atherton on the road to Herberton. The description was publish in the journal Telopea.[3][4] The specific epithet is derived from the neo-Latin word graniticus, relating to granite, referring to the usual habitat of this species.[3]

Granite ironbark is common on undulating country, growing in granite and volcanic soils from the Atherton Tableland to Paluma.[2][3]

This eucalypt is classified as "least concern" under the Queensland Government Nature Conservation Act 1992.[5]
