Template:Short description Template:Use dmy dates Template:Speciesbox
Grevillea baueri, commonly known as Bauer's grevillea,[1] is a species of flowering plant in the family Proteaceae and is endemic to the coastal ranges of south-eastern New South Wales. It is a low, spreading to erect shrub with mostly oblong to egg-shaped leaves with red to pink and cream-coloured or yellow flowers.
Description
Grevillea baueri is a low, spreading to erect shrub that typically grows to a height of up to Template:Cvt. Its leaves are simple, oblong to egg-shaped, Template:Cvt long and Template:Cvt wide with the edges turned down or rolled under, the lower surface more or less glabrous. The flowers are arranged in groups of eight to eighteen near the ends of branches or in leaf axils on a rachis Template:Cvt long, and are red to pink and cream-coloured to yellow near the tip, with a red style. The pistil is usually Template:Cvt long, the ovary covered with long hairs. Flowering mainly occurs in winter and spring and the fruit is a hairy follicle Template:Cvt long.[1][2][3]
Taxonomy
Grevillea baueri was first formally described in 1810 by botanist Robert Brown in Transactions of the Linnean Society of London.[4][5] The specific epithet honours brothers Franz and Ferdinand Bauer who were both noted botanical illustrators from Austria.[3]
In 1986, Donald McGillivray described two subspecies of G. baueri and the names are accepted by the Australian Plant Census:
- Grevillea baueri subsp. asperula McGill.[6] is often an open plant with leaves Template:Cvt wide, the upper surface rough with many granules, and has branched, down-curved flower groups;[7][8]
- Grevillea baueri R.Br. subsp. baueri[9] is often a compact plant with leaves Template:Cvt wide, the upper surface mostly smooth, and has simple, erect flower groups.[10][11]
Distribution and habitat
Subspecies asperula grows in heath or open woodland from near Nerriga to near Nowra and the northern edge of the Budawang Range and subsp. baueri is found in woodland and heath between Camden, Picton, Mittagong and Bundanoon in the coastal ranges of south-eastern New South Wales.[7][8][10][11]
Conservation status
Grevillea baueri is listed as Vulnerable on the IUCN Red List of Threatened Species. It has a limited distribution which is likely severely fragmented and the number of mature individuals, as well as the quality and extent of habitat are declining.[12]
Use in horticulture
This species has attractive foliage and flowers although the latter blacken after maturity, which can detract from the overall appearance. It is frost hardy in Australia and preferes a position with reasonable drainage and in full sun or partial shade. Plants are propagated by cuttings.[3]
