Thryptomene hubbardii is a species of flowering plant in the family Myrtaceae and is endemic to a small area in the west of Western Australia. It is a spreading shrub with crowded broadly egg-shaped leaves with the narrower end towards the base, and flowers with five pale pink petals and nine or ten stamens.
Thryptomene hubbardii is a spreading shrub that typically grows to high and wide. Its leaves are crowded on the branchlets, pointing upwards or pressed against the stem, broadly egg-shaped with the narrower end towards the base, long and wide on a petiole long. The flowers are arranged in small clusters of two to four pairs of flowers on a peduncle long with bracteoles long that remain until the fruit falls. The flowers are in diameter with broadly heart-shaped sepals long and keeled. The petals are usually pale pink, long and there are nine or ten stamens. Flowering occurs from August to December.[1]
Thryptomene hubbardii was first formally described in 2014 by Barbara Lynette Rye and Malcolm Eric Trudgen in the journal Nuytsia from specimens collected by near Mullewa by Bronwen and Gregory Keighery in 2004.[2] The specific epithet (hubbardii) honours Richard T. Hubbard, who prepared a detailed but unpublished manuscript for the Myrtaceae of Western Australia.
This thryptomene grows in tall shrubland and mallee woodland from the East Yuna Nature Reserve to Indarra Springs Nature Reserve in the Avon Wheatbelt and Geraldton Sandplains biogeographic regions of Western Australia.
Thryptomene hubbardii is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife meaning that it is poorly known and from only one or a few locations.[3]
