Eucalyptus luteola

Eucalyptus luteola is a species of mallee that is endemic to a small area of Western Australia. It has smooth grey bark with rough greyish ribbons near the base, linear to narrow lance-shaped adult leaves, flower buds in groups of eleven to thirteen, lemon-coloured flowers and cylindrical to barrel-shaped fruit.

Description
Eucalyptus luteola is a mallee that typically grows to a height of 1 to 5 m and forms a lignotuber. It has smooth grey bark with rough and greyish ribbons at the base. Young plants have egg-shaped to lance-shaped leaves that are up to 70 mm long and 30 mm wide. Adult leaves are the same shade of slightly glossy green on both sides, linear to narrow lance-shaped, 60-95 mm long and 8-15 mm wide, tapering to a petiole 7-17 mm long. The flower buds are arranged in leaf axils on a flattened, unbranched peduncle 10-17 m long, the individual buds on pedicels 3-5 mm long. Mature buds are spindle-shaped, 18-19 mm long and 3-4 mm wide with a horn-shaped operculum about three times as long as the floral cup. Flowering occurs from February to April and the flowers are lemon-coloured. The fruit is a woody cylindrical to barrel-shaped capsule 6-8 mm long and 5-7 mm wide.

Taxonomy and naming
Eucalyptus luteola was first formally described in 1991 by Ian Brooker and Stephen Hopper from a specimen collected by Hopper near Lake King in 1985. The description was published in the journal Nuytsia. The specific epithet (luteola) is a Latin word meaning "pale yellow", referring to the flower colour.

Distribution and habitat
This mallee is found in undulating country between Hyden and Ravensthorpe where it grows in sandy soils.
