Calothamnus montanus is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an erect shrub with short, needle-shaped leaves and red flowers with four stamen bundles. (In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca georgi.)[1]
Calothamnus montanus is a shrub growing to a height of about 2m (07feet) with stems that are hairy at first but become glabrous and thick over time. Its leaves are needle-like, mostly NaNmm long and NaNmm wide and circular in cross section.[2]
The flowers have 4 sepals and 4 petals. The stamens are partly red, partly green and are arranged in 4 claw-like bundles, each about NaNmm long. The petals are NaNmm long. Flowering occurs from October to January and is followed by fruits which are woody, flattened spherical capsules, NaNmm long and partly buried in the stem.
Calothamnus montanus was first formally described in 2010 by Alex George from a specimen found in the Stirling Range National Park.[3] The specific epithet (montanus) is "from the Latin montanus (montane), in reference to the occurrence".
Calothamnus montanus occurs in the Stirling Range National Park in the Esperance Plains biogeographic region where it grows in soil derived from metamorphic rocks.[4]
Calothamnus montanus is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
