Eucalyptus pauciflora subsp. debeuzevillei, commonly known as Jounama snow gum,[2] is a mallee or small tree that is native to a few mountain peaks in south-eastern Australia. It has smooth, shiny bark, glossy green lance-shaped to egg-shaped leaves, flower buds in groups of between nine and fifteen, white flowers and hemispherical or conical fruit. It differs from other subspecies of E. pauciflora in having angular flower buds.
Eucalyptus pauciflora subsp. debeuzevillei is a mallee or tree that typically grows to a height of 12 m (39 ft) and forms a lignotuber. The branchlets are usually glaucous. The bark is smooth, grey, white, cream-coloured or light brown and often has insect scribbles. Young plants and coppice regrowth have dull bluish green or glaucous, egg-shaped to broadly lance-shaped leaves that are 60–90 mm (2.4–3.5 in) long and 30–55 mm (1.2–2.2 in) wide and petiolate. Adult leaves are broadly lance-shaped to lance-shaped or curved, 75–180 mm (3.0–7.1 in) long and 16–50 mm (0.63–1.97 in) wide on a petiole 12–25 mm (0.47–0.98 in) long. The flower buds are arranged in leaf axils in groups of between nine and fifteen on an unbranched peduncle 4–13 mm (0.16–0.51 in) long, the individual buds on pedicels up to 2 mm (0.079 in) long. Mature buds are club-shaped to oblong, 8–12 mm (0.31–0.47 in) long and 4–6 mm (0.16–0.24 in) wide with a conical operculum. Flowering has been recorded in December and January and the flowers are white. The fruit is a woody cup-shaped, barrel-shaped or conical capsule 8–13 mm (0.31–0.51 in) long and 7–12 mm (0.28–0.47 in) wide with the valves near rim level or below it. Subspecies debeuzevillei differs from others in the species in having mature buds that are strongly angular.[2][3]
