Eucalyptus rudderi is a tree that typically grows to a height of 30–40 m (98–131 ft) and forms a lignotuber. It has rough, fibrous or flaky grey bark on the trunk and branches. Young plants and coppice regrowth have stems that are square in cross-section, and narrow lance-shaped, dull green leaves that are 35–50 mm (1.4–2.0 in) long and 5–10 mm (0.20–0.39 in) wide. Adult leaves are the same shade of green on both sides, lance-shaped, 70–130 mm (2.8–5.1 in) long and 12–25 mm (0.47–0.98 in) wide, tapering to a petiole 8–15 mm (0.31–0.59 in) long. The flower buds are arranged on the ends of branchlets in groups of seven on a branched peduncle 5–10 mm (0.20–0.39 in) long, the individual buds on pedicels 3–4 mm (0.12–0.16 in) long. Mature buds are oval, about 3 mm (0.12 in) long and 2–3 mm (0.079–0.118 in) wide with a conical operculum. Flowering occurs from March to April and the flowers are white. The fruit is a woody barrel-shaped or hemispherical capsule 3–4 mm (0.12–0.16 in) long and 4–5 mm (0.16–0.20 in) wide with the valves near rim level. [2] [3] [4]
Eucalyptus rudderi was first formally described in 1905 by Joseph Maiden in Proceedings of the Linnean Society of New South Wales . The type specimen was collected by Augustus Rudder (1928–1904) at Cundletown. [5] The specific epithet (rudderi) honours the collector of the type material. [6] [7]
Rudder's box grows in shallow soil on steep slopes in forest in the Taree-Karuah area. [3] [4]
