Prostanthera galbraithiae

Prostanthera galbraithiae, commonly known as Wellington mint-bush, is a flowering plant in the family Lamiaceae. It is endemic to Victoria in Australia.[2]


The species is a subshrub or shrub to between 0.1 and 2 metres high.[3] It has aromatic, sessile leaves which are usually strongly revolute and 8–15 mm long and 2–3 mm wide.[3] The flowers are deep-mauve to purple with maroon spots in the centre and appear in September and October in the species native range.[2][3]


The species was first formally described by botanist Barry J. Conn in 1998 in Telopea.[1] The species epithet is named for Jean Galbraith, a member of the Latrobe Valley Field Naturalists, who co-discovered the species and advocated for its protection.[3]

Distribution and habitat[edit]

The species occurs on sandy soils over clay on the Gippsland plains in Holey Plains State Park.[3] It is associated with Eucalyptus obliqua woodland with a heathy understorey including species such as Acacia oxycedrus, Epacris impressa, Lepidosperma concavum, Leptospermum myrsinoides and Platylobium obtusangulum.[3] It can become locally common after fire.[3] However, a population at Dutson Downs appears to have become extinct due to overly-frequent fires.[2]
