Description

Eucalyptus comitae-vallis is a mallee, rarely a tree, that typically grows to a height of 2 to 7 metres (7 to 23 ft) and forms a lignotuber. The bark is rough, ribbony and grey on the trunks and larger branches then smooth and pinkish grey yellow-green above. Leaves on young plants and coppice regrowth are dull, greyish, 55–80 mm (2.2–3.1 in) long and 10–20 mm (0.39–0.79 in) wide and always have a petiole. Adult leaves are linear to narrow lance-shaped, the same more or less glossy green on both sides, 60–100 mm (2.4–3.9 in) long and 6–15 mm (0.24–0.59 in) wide on a petiole 8–15 mm (0.31–0.59 in) long. The flower buds are arranged in groups of seven, nine or eleven in leaf axils on a peduncle 6–12 mm (0.24–0.47 in) long, the individual buds on a pedicel 2–6 mm (0.079–0.236 in) long. Mature buds are cylindrical to narrow pear-shaped, 5–6 mm (0.20–0.24 in) long and 3–4 mm (0.12–0.16 in) wide with a rounded to flattened operculum with a short beak. Flowering occurs from February to April and the flowers are white. The fruit is a woody, barrel-shaped to conical or cup-shaped capsule 5–8 mm (0.20–0.31 in) long and 5–7 mm (0.20–0.28 in) wide on a pedicel 2–8 mm (0.079–0.315 in) long and with the valves at rim level.

Taxonomy

Eucalyptus comitae-vallis was first formally described in 1923 by Joseph Maiden from a specimen collected from Comet Vale by John Thomas Jutson. The description was published in Maiden's book, A Critical Revision of the Genus Eucalyptus. The specific epithet (comitae-vallis) is the latinised version of the type location.

In 1934, William Blakely described Eucalyptus brachycorys but the name is considered by the Australian Plant Census to be a synonym.

Distribution

Comet Vale mallee is mainly found between Menzies and Kalgoorlie in the Mid West, Wheatbelt and Goldfields-Esperance regions of Western Australia where it grows in sandy-clay-loamy soils in open shrubland.

Conservation status

This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
