Eucalyptus roycei is a mallee or a small tree that typically that grows to a height of 2–6 m (6 ft 7 in – 19 ft 8 in) and forms a lignotuber. It has rough fibrous or flaky greyish bark at the base, smooth greyish to cream-coloured bark above. Young plants and coppice regrowth have egg-shaped to lance-shaped leaves that are 60–125 mm (2.4–4.9 in) long and 30–60 mm (1.2–2.4 in) wide. Adult leaves are the same shade of dull greyish green on both sides, lance-shaped to curved, 65–140 mm (2.6–5.5 in) long and 18–30 mm (0.71–1.18 in) wide, tapering to a petiole 10–30 mm (0.39–1.18 in) long. The flower buds are arranged in leaf axils in groups of seven or nine on an unbranched peduncle 9–28 mm (0.35–1.10 in) long, the individual buds on pedicels 2–6 mm (0.079–0.236 in) long. Mature buds are cylindrical to oval, 14–21 mm (0.55–0.83 in) long and 8–11 mm (0.31–0.43 in) wide with a conical to rounded operculum and a four-sided floral cup. Flowering occurs between January and March and the flowers are white, cream-coloured or pale yellow. The fruit is a woody, cylindrical to barrel-shaped, four-sided capsule 15–30 mm (0.59–1.18 in) long wide with the valves below the level of the rim. [2] [3] [4]
Eucalyptus roycei was first formally described in 1970 by Maisie Carr, Denis Carr and Alex George in Proceedings of the Royal Society of Victoria . The type specimen was collected near Hamelin Pool in 1966 by Eleanor Marion Scrymgeour and Maisie Carr. [5] [6] [7] The specific epithet (roycei) honours Robert Dunlop Royce who was a member of the staff of the Western Australian Herbarium. [6]
Shark Bay mallee is found on sand plains in the Gascoyne region centred around Shark Bay where it grows in red calcareous sandy soils. [2] The mallee is part of the tree heath community found in Shark Bay at the overlap of the South West botanical province and the Eremaean botanical province. Associated species include Eucalyptus beardiana , Grevillea rogersoniana , Acacia drepanophylla , Banksia ashbyi and Grevillea rogersoniana . [8]
