Regelia megacephala is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a taller shrub than others in its genus, with small, rounded leaves and clusters of purplish-red flowers from October to December.
Regelia megacephala is an erect, straggly shrub which grows to a height of 2–5 m (7–20 ft). Its leaves are small and are arranged in alternating pairs (decussate) so that they make four rows along its long stems. [2]
The flowers are mauve and arranged in dense heads 15 mm (0.6 in) across on the ends of long stems which continue to grow after flowering. There are 5 sepals, 5 petals and 5 bundles of stamens. Flowering occurs from September to December and is followed by fruit which are woody capsules. [2]
Regelia megacephala was first formally described in 1964 by the Australian botanist, Charles Gardner in Journal of the Royal Society of Western Australia. [1] The specific epithet (megacephala) means "large-headed". [3]
Regelia megacephala grows in red sand on rocky quartzite hills in the Avon Wheatbelt and Swan Coastal Plain biogeographic regions. [2] [4] It is closely associated with Coomberdale chert which is mined for the production of silicon and is threatened by mining activity. [5] [6]
Regelia megacephala is classified as "Priority Four" by the Western Australian Government Department of Parks and Wildlife [4] meaning that is rare or near threatened. [7]
Regelia megacephala is not often seen in cultivation but is frost hardy, will grow in full or partial sun and is suitable for narrow gardens. [2] [8] Its commercial potential for export as a Christmas flower has been assessed. [9]

Regelia is a genus of flowering plants in the family Myrtaceae and is endemic to the south-west of Western Australia. The genus is composed of five species of small leaved, evergreen shrubs which have heads of flowers on the ends of branches which continue to grow after flowering.

Eremaea is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to the south-west of Western Australia. Little study of the genus as a whole had been undertaken until Roger Hnatiuk researched Eremaea and published a paper in 1993, A revision of the genus Eremaea (Myrtaceae) in Nuytsia. The first species to be described was Eremaea pauciflora in 1837 and by 1964, the number of species known had increased to 12. Hnatiuk recognised 16 species, 5 subspecies and a number of varieties.
