Eucalyptus delegatensis, commonly known as alpine ash, gum-topped stringybark, white-top[3] and in Victoria as woollybutt,[4] is a species of tree that is endemic to southeastern Australia. It has a straight trunk with rough, fibrous to stringy bark on the lower half of the trunk, smooth white bark above, lance-shaped to curved adult leaves, flower buds in groups of between seven and fifteen, white flowers and barrel-shaped or hemispherical fruit.

Description

Eucalyptus delegatensis is a tree that typically grows to a height of 40–50 m (130–160 ft), sometimes to 90 m (300 ft), and forms a

capsule 6–11 mm (0.24–0.43 in) long and wide with the valves near rim level or enclosed in the fruit.[3][5][6][7]

Taxonomy and naming

Eucalyptus delegatensis was first formally described in 1900 by Richard Thomas Baker from a specimen collected by William Baeuerlen, (previously known as Wilhelm Bäuerlen) on "Delegate Mountain". The description was published in Proceedings of the Linnean Society of New South Wales.[8][9] The specific epithet (delegatensis) refers to the type location.[3]

In 1985 Douglas John Boland described two subspecies and the names have been accepted by the Australian Plant Census:

  • Eucalyptus delegatensis R.T.Baker subsp. delegatensis[10] that has broadly lance-shaped juvenile leaves and is found in New South Wales and Victoria;
  • Eucalyptus delegatensis subsp. tasmaniensis Boland[11] that has more or less round juvenile leaves with a short "drip-tip" and only grows in Tasmania.[12]

Distribution and habitat

Alpine ash is widespread and often dominant in grassy or wet

Victoria it occurs at altitudes between 900 and 1,500 m (3,000 and 4,900 ft) east of Mount Macedon. Subspecies tasmaniensis is endemic to Tasmania.[6][7]
