Calothamnus lehmannii, commonly known as dwarf claw flower, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a low-lying, sometimes ground-hugging shrub with long, thin, cylindrical leaves and clusters of red flowers that are smaller than any others in the genus Calothamnus.

Description

Calothamnus lehmannii grows to a height of about 0.5 metres (1.6 ft). Its leaves are 10–25 millimetres (0.4–1 in) long and circular in cross section.[1][2]

The flowers are arranged in small clusters and partly buried in the corky bark of the stems. They are red and have 4 sepals, 4 petals and 4 claw-like bundles of stamens, all less than 10 millimetres (0.4 in) long. The upper two bundles contain only 4 or 5 stamens and the lower ones are reduced to a single stamen. Flowering occurs between August and October and is followed by fruits which are woody capsules.[1][2]

Taxonomy and naming

Calothamnus lehmannii was first formally described by Johannes Schauer in 1843 in Dissertatio phytographica de Regelia, Beaufortia et Calothamno.[3] The specific epithet (lehmannii) honours the German botanist, Johann Lehmann.[4] (In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca johannis-lehmannii.)[4]

Distribution and habitat

Calothamnus lehmannii occurs in and between the Bowelling and Stirling Range districts in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Warren biogeographic regions.[1][2] It grows in sandy soils on plains and hillsides.[5]

Conservation

Calothamnus lehmannii is classified as "not threatened" by the Western Australian government department of parks and wildlife.[2]
