Urn Gum (Eucalyptus urnigera)
Description
E. urnigera is an evergreen tree that typically grows to a height of 5 to 15 metres (16 to 49 ft), although specimens up to 45 m (148 ft) have been recorded in sheltered lower altitude positions. The spread of the tree is typically to 10 metres (33 ft). The tree often has a gnarled appearance in exposed areas and has a lignotuber. However in more sheltered and lower altitude sites it grows tall and straight. This is very obvious on the road leading up to Lake Fenton in the Mount Field National Park. The bark is deciduous, peeling in flakes, the branches are smooth, grey, orange-tan to olive green over cream. Branchlets are often glaucous. As with most eucalypts juvenile leaves are distinct from adult leaves in both arrangement and shape. The juvenile leaves are opposite, sessile, orbate to elliptical, apex either rounded on mucronulate (with a small tip) and a crenulated (finely notched or scalloped) margin, 3 to 6 centimetres (1.2 to 2.4 in) long. The leaves range from being dark green (sheltered environment) to highly glaucous in exposed areas. Adult leaves are alternate, petiolate, narrow-lanceolate to ovate, dark green, glossy and coriaceous (leathery). They are typically 6 to 12 cm (2.4 to 4.7 in) long and 1.2 to 4 cm (0.47 to 1.57 in) wide. Lateral veins diverge at angles of 25-60 degrees.
