Regelia is a genus of flowering plants in the family Myrtaceae. This genus is composed of small leaved, evergreen shrubs and trees which are endemic to Australia. Five of the six species are endemic to the south-west of Western Australia, the other species endemic to Kakadu National Park in the Northern Territory (R. punicea). Species range from 1-6 meters in height.[1] They are noted for bearing essential oils.[1] Typically showy blooms are aggregate inflorescences which take the form of heads or spikes depending upon the species. Fruits are a woody, 3-valved capsule which often split upon maturity.
Etomology and taxonomy
The genus was first formally described by J.C.Schauer in 1843 who gave it the name Regelia in honour of German gardener and botanist Eduard August von Regel.
Regelia is closely related to Melaleuca, both have stamens which are fused into clusters. The primary difference between the genera is that in Regelia the anthers are attached at the base and in Melaleuca they are attached at the side.[2] These genera are also closely related to Beaufortia, Calothamnus and Eremaea.[2]
Species
There are currently six recognized species of Regelia. All are endemic to small geographic regions in southwestern or north-central Australia.
- Regelia ciliata Schauer is a rigid spreading shrub which grows 1.3 m to 1.5 m across, it has with tiny wedge shaped leaves, and paper-like bark on the stems.[3]
- Regelia cymbifolia (Diels) C.A.Gardner is a much branched, upright shrub of about 2 meters in height, and bearing tiny wedge shaped leaves. It blooms in the spring, producing clusters of many small heads.
- Regelia inops (Schauer) Schauer is an upright but often spreading shrub which can grow to 0.75–2.5 m and has tiny wedge shaped leaves.[4]
- Regelia megacephala C.A.Gardner is a rare, 2-5 meter tall Shrub, which larger (but still small) rounded leaves.[5]
- Regelia velutina (Turcz.) C.A.Gardner (Barrens regelia) is the showiest and largest member of the genus is a large shrub or small which can grow up to 6 meters. It is noted for growing on very poor dry soils and having large flower heads.[6]
- Regelia punicea (N.Byrnes) Barlow is an unspecialized member found in the Northern Territory. This species was recently reassigned from genus Melaleuca.[7]
