Description.
"Agonis grandiflora" is an erect, often straggly sbrub that typically grows to a height of and has many stems that are hairy at first, later glabrous. The leaves are sessile, linear, densely clustered, long and wide with a small point on the tip. The flowers are arranged singly or in groups of 2, 3 or 4 in upper leaf axils. There are bracts, and bracteoles long. The floral tube is long, the sepals broadly elliptic to broadly egg-shaped long. The petals are spatula-shaped, often suffused with pink, long and across. There are 22 to 35 stamens with filaments long. Flowering mainly occurs from September to November, and the fruit is a capsule long and wide.
Taxonomy.
"Agonis grandiflora" was first formally described in 1867 by George Bentham in his "Flora Australiensis". In 2007, Judith R. Wheeler and Neville G. Marchant transferred the species to the genus "Paragonis" as "P. grandiflora", and that name is accepted by the Western Australian Herbarium and the Australian Plant Census, but not accepted by Plants of the World Online.
Distribution and habitat.
This species grows in woodland and scrub in a few locations on the Darling Scarp in the Jarrah Forest and Swan Coastal Plain bioregions in the south-west of Western Australia.
