Corymbia bloxsomei, commonly known as yellowjack, yellow jacket or yellow bloodwood,[1] is a species of tree that is endemic to inland, south-eastern Queensland. It has thick, rough scaly bark on the trunk and larger branches, lance-shaped or curved adult leaves, flower buds in groups of seven, nine or eleven, creamy white to pale yellow flowers and barrel-shaped, urn-shaped or spherical fruit.
Corymbia bloxsomei is a tree that typically grows to a height of and forms a lignotuber. It has soft, rough, scaly or tessellated yellowish to brownish bark on the trunk and almost to the smaller branches. Young plants and coppice regrowth have leaves that are paler on the lower surface, egg-shaped to elliptical, long and wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped or curved, long and wide, tapering to a petiole long. The flower buds are arranged on the ends of branchlets on a branched peduncle long, each branch of the peduncle with seven, nine or eleven buds on pedicels long. Mature buds are oval to cylindrical, about long and wide with a variably-shaped operculum. Flowering has been recorded in June and December and the flowers are creamy white to pale yellow. The fruit is a woody barrel-shaped, urn-shaped or spherical capsule long and wide with the valves enclosed in the fruit.[2] [3]
Yellowjacket was first formally described in 1925 by Joseph Maiden in the Journal and Proceedings of the Royal Society of New South Wales and given the name Eucalyptus bloxsomei.[4] [5] In 1995, Ken Hill and Lawrie Johnson changed the name to Corymbia bloxsomei.[6] [3] The specific epithet (bloxsomei) honours "Herbert Schreiber Bloxsome".
Corymbia bloxsomei grows in forest on flat or sloping areas from near Mundubbera to Chinchilla, especially in the Barakula State Forest.
This eucalypt is classified as of "least concern" under the Government of Queensland Nature Conservation Act 1992.[7]
