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 . It has tessellated grayish bark on the trunk and branches. Adult leaves are arranged in opposite pairs, sessile, the same greyish green on both sides, broadly lance-shaped, long and wide. The flower buds are arranged in groups of between seven and eleven on a thick or slightly flattened peduncle long, with the individual buds on thick pedicels up to long. Mature buds are oval or pear-shaped, the floral cup long and wide, and the operculum hemispherical, long and wide, with a small point on the top. The fruit is a woody oval or urn-shaped capsule long and 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 This eucalypt grows in woodland in the western Kimberley region of Western Australia.
