Description
Eucalyptus calyerup is a tree that typically grows to a height of Шаблон:Convert and rarely forms a lignotuber. It has smooth pale cream to pale pink bark above a dark grey stocking of rough bark on the lowest Шаблон:Cvt of the trunk. Young plants have leaves that are bluish green, egg-shaped, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are egg-shaped to elliptic, sometimes lance-shaped, the same glossy green on both sides, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven in leaf axils on a flattened peduncle Шаблон:Cvt long, the individual flowers on a pedicel Шаблон:Cvt long. Mature buds are Шаблон:Cvt long, Шаблон:Cvt wide with a horn-shaped operculum that is narrower than, but about twice as long as the floral cup. Flowering occurs between October and December and the flowers are creamy yellow. The fruit is a woody, conical to bell-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide on a pedicel Шаблон:Cvt long.[1][2][3]
Taxonomy and naming
Eucalyptus calyerup was first formally described in 2002 by Nathan K. McQuoid and Stephen Hopper from a specimen collected from near Calyerup Rocks, east of Jerramungup. The description was published in the journal Nuytsia.[4] The specific epithet (calyerup) refers to the type location. The ending -ensis is a Latin suffix "denoting place, locality [or] country".[3][5]
This species is possibly a stabilised hybrid between E. occidentalis and E. platypus, although the latter species does not occur in the same location.[3]
Distribution and habitat
This eucalypt is found around rocky outcrops in the Great Southern region of Western Australia between Katanning and Jerramungup where it grows in sandy-loam soils over granite.[1]
Conservation
This species is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[1] meaning that it is known from only one or a few locations which are potentially at risk.[6]
Use in horticulture
Eucalyptus calyerup has been used extensively by the local Landcare group and has been shown to be resistant to lerp attack.[3]
