Shawia avicenniifolia, commonly known as mountain akeake, is a flowering plant in the family Asteraceae.[2] It is endemic to New Zealand where it is found on the southern coastlines of the South Island and on Stewart Island.[3] It is classified as Not Threatened.[4]
Description
Mountain akeake is a small, bushy shrub or tree that grows up to 6 metres tall[5] and 3 metres wide.[3] It has thin, papery bark[6] and angular branchlets covered in white tomentum.[5] Leaves are oblong-lanceolate in shape.[5] They are dark green in colour with a downy, white underside.[2] Leaf length varies between 5–10 cm long and 3–5 cm wide.[7]
Flowers are clustered and daisy-like with white rays and purple central disks. They emerge between November and February and have a sweet scent.[3][5] Flowers are about 5 centimetres wide and carried in clusters of three to ten.[3] The flowers develop into fluffy seeds.[2]
Taxonomy
The species was first described in 1846 by Étienne Raoul as Shawia avicenniifolia[8] and transferred to the Olearia genus by Joseph Dalton Hooker in 1864.[2][9][9] Recent phylogenetic and morphological data has led to the reinstatement of the genus Shawia, including S. avicenniifolia.[10][1]
