Regelia cymbifolia is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a much branched shrub bearing tiny, wedge shaped leaves and clusters of deep pink to purple flowers on the ends of its branches in spring.

Description

[edit]

Regelia cymbifolia is much branched shrub which grows to a height of 2 m (7 ft). The leaves are arranged in alternating pairs (decussate), so that they make four rows along the stems. They are egg-shaped, usually less than 4 mm (0.16 in) long, curved with their lower half pressed against the stem and have a prominent mid-vein.[2]

The flowers are deep pink to purple and arranged in small clusters on the ends of branches that continue to grow after flowering. There are 5 sepals, 5 petals and 5 bundles of stamens. Flowering occurs between August and November and is followed by fruit which are woody capsules.[2][3]

Taxonomy and naming

[edit]

Regelia cymbifolia was first formally described in 1905 by Ludwig Diels in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie and tentatively given the name Beaufortia ? cymbifolia.[4][5] In 1964, Charles Gardner recognised the specimen as Regelia cymbifolia in Journal of the Royal Society of Western Australia.[6] The specific epithet (cymbifolia) is from the Latin cymba meaning "a boat" and -folius meaning "leaved".[2][7]

Distribution and habitat

[edit]

Regelia cymbifolia occurs in a restricted area near the Stirling Range in the Avon Wheatbelt, Esperance Plains and Jarrah Forest biogeographic regions.[2] It grows in sand on undulating plains.[8]

Conservation

[edit]

Regelia cymbifolia is classified as "Priority Four" by the Western Australian Government Department of Parks and Wildlife[3] meaning that it is rare or near threatened.[9]

Use in horticulture

[edit]

Regelia cymbifolia is not well known in cultivation but has been grown in Kings Park.[2]
