Banksia audax is a species of shrub that is endemic to Western Australia. It has fissured, grey bark, woolly stems, hairy, serrated leaves and golden orange flower spikes.
Banksia audax is a shrub that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has fissured, grey bark and branches densely covered with woolly hairs. The leaves are wedge-shaped, hairy on both sides, Шаблон:Cvt long and Шаблон:Cvt wide with serrated edges. The serrations are triangular, Шаблон:Cvt long and sharply pointed. The flower spike is erect, on a short side branch, oval-cylindrical and Шаблон:Cvt in diameter as the flowers open. The flowers are golden orange, each with a perianthШаблон:Cvt long and hairy on the outside. Flowering occurs from November to January and there are up to forty elliptic follicles in the spike, each Шаблон:Cvt long, Шаблон:Cvt high and Шаблон:Cvt wide and hairy.[1][2][3]
Taxonomy and naming
Banksia audax was first formally described in 1928 by Charles Gardner from specimens he collected in 1926.[4][5] Gardner gave it the specific name "audax", meaning "bold" in Latin, in recognition of its "boldness" in growing so far inland.[3][6]
This shrub belongs to subgenus Banksia, section Banksia, series Cyrtostylis. It has no close relatives. B. benthamiana (Bentham's banksia) and B. laevigata (tennis ball banksia) are taxonomically closest to it, but these are both larger shrubs without lignotubers.
Distribution and habitat
Banksia audax occurs from near the town of Southern Cross, south almost to the coast. It occurs amongst heath and in mallee communities, growing in sandy yellow loam.[1][2][3]
