Eucalyptus × lamprocalyx

Eucalyptus × lamprocalyx is a tree or shrub that is endemic to the Kimberley region of Western Australia. It has tessellated bark on its trunk and branches, sessile, broadly lance-shaped leaves arranged in opposite pairs, flower buds in groups of between seven and eleven and oval or urn-shaped fruit. It is considered to be a natural hybrid between Corymbia cadophora and C. polycarpa.

Description
Eucalyptus × lamprocalyx is a crooked, spreading tree or shrub that grows to a height of up to 6 m. It has tessellated greyish bark on the trunk and branches. Adult leaves are arranged in opposite pairs, sessile, the same greyish green on both sides, broadly lance-shaped, 120-250 mm long and 50-80 mm wide. The flower buds are arranged in groups of between seven and eleven on a thick or slightly flattened peduncle 12-25 mm long, the individual buds on thick pedicels up to 3 mm long. Mature buds are oval or pear-shaped, the floral cup 8-12 mm long and 8-10 mm wide and the operculum hemispherical, 4-5 mm long and 5-6 mm wide with a small point on the top. The fruit is a woody oval or urn-shaped capsule 30-40 mm long and 20-30 mm wide.

Taxonomy and naming
Eucalyptus × lamprocalyx was first formally described in 1834 by William Blakely who gave it the name Eucalyptus lamprocalyx and published the description in his book, A Key to the Eucalypts. The Australian Plant Census considers this tree to be a natural hybrid between Corymbia cadophora and C. polycarpa, but it does not yet have a name in the genus Corymbia.

Distribution and habitat
