Andersonia macranthera is a spindly erect, or straggling shrub that typically grows to a height of more than . Its leaves are pointed egg-shaped to linear, mostly long and wide with the ends curved backwards. The flowers are arranged with about twelve leaves and bracteoles on the flower stalk. The sepals are lance-shaped, about long and blue or pink when dried. The petals are pink, pinkish blue or pinkish purple and red, forming a tube shorter than the sepals, with lobes about half as long as the petal tube and bearded in the lower half. The stamens are about long and longer than the petal tube, the anthers longer than the filaments.[1]
Andersonia macranthera was first formally described in 1864 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae.[2] [3] The specific epithet (macranthera) means 'large' or 'long anthers'.[4]
This species of Andersonia grows in sand on sandplains near Esperance in the Esperance Plains and Mallee bioregions of south-western Western Australia.
Andersonia macranthera is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
