Crowea angustifolia is a flowering plant in the family Rutaceae, which is endemic to Western Australia. It is an erect shrub growing to 3 m high by 1 m in diameter with white or pink flowers in spring.[1]
Description
C.angustifolia is a variable shrub, from 0.3 - 3.5 m high, erect or spreading and diffuse. The leaves are narrow and linear (especially var. angustifolia) to oval with toothed edges (especially in var. platyphylla). Flowers occur singly in the axils of the leaves from September to December and are white or pink with five petals, five sepals and ten stamens in separate rings around the central ovary.
Taxonomy
C. angustifolia was described by James Edward Smith in 1808 from a specimen collected by "Mr Menzies, found near King George's Sound".[2][3] The specific epithet (angustifolia) is derived from Latin, angustus = narrow and folium = leaf.[4]
Two varieties are recognised:[2]
- C. angustifolia var. angustifolia Benth.(1863)
- C. angustifolia var. platyphylla Benth. = C. angustifolia var. dentata R.Br ex Benth. Gebert
Distribution and habitat
The species is endemic to the south western corner of Western Australia, in the Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions growing on sandy soils, gravel, granite, ridge tops, slopes and outcrops (although var. platyphylla is absent from the Swan Coastal Plain).[5]
