Eucalyptus calyerup
Eucalyptus calyerup is a tree that is endemic to a small area in the south-west of Western Australia. It has rough, fibrous bark on the lower part of the trunk, smooth bark above, elliptic to lance-shaped adult leaves, flower buds in groups of seven, creamy-yellow flowers and conical to bell-shaped fruit.
Description
Eucalyptus calyerup is a tree that typically grows to a height of 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 of the trunk. Young plants have leaves that are bluish green, egg-shaped, long and wide. Adult leaves are egg-shaped to elliptic, sometimes lance-shaped, the same glossy green on both sides, long and wide on a petiole long. The flower buds are arranged in groups of seven in leaf axils on a flattened peduncle long, the individual flowers on a pedicel long. Mature buds are long, 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 long and wide on a pedicel long.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. The specific epithet refers to the type location. The ending -ensis is a Latin suffix "denoting place, locality country".This species is possibly a stabilised hybrid between E. occidentalis and E. platypus, although the latter species does not occur in the same location.
