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.
Taxonomy and namingEdit
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. The specific epithet is derived from the neo-Latin word graniticus, relating to granite, referring to the usual habitat of this species.
