Description

Eucalyptus hawkerii is a mallee or slender tree that typically grows to a height of Шаблон:Cvt. It has rough, scaly or fibrous bark on the lower half of its trunk, smooth light grey to brownish bark above. Young plants have lance-shaped to narrow elliptical leaves that are dull bluish green, slightly paler on the lower side, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. Adult leves are lance-shaped, sometimes curved, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on an unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are oval to spindle-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with a conical operculum about half as long as the floral cup. Flowering occurs in autumn and the flowers are white. The fruit is a woody, more or less cylindrical or barrel-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves below rim level.[1][2]

Taxonomy and naming

Eucalyptus hawkeri was first formally described in 2004 by Kevin Rule from a specimen collected on Mount Arapiles and the description was published in the journal Muelleria.[3] The specific epithet honours the park ranger, Peter Hawker, for his contribution to the understanding of this species.[2]

Distribution and habitat

This mallee is only known from the Mt. Arapiles area and nearby reserves where it grows in remnant woodland.[1][2]

The total population of the species is estimated at around 1,300 individuals spread over 10 main sub-populations. The population is thought to currently be stable although it is severely fragmented. The International Union for the Conservation of Nature listed it as a vulnerable species in 2019.[4]
