Pimelea sessilis is an erect shrub that typically grows to a height of with dense tufts of hair in its leaf axils. The leaves are sessile to almost stem-clasping, narrowly elliptic to almost round, long and wide. The flowers are arranged in heads on a peduncle long, surrounded by 4 broadly elliptic to almost round involucral bracts long and wide, each flower on a pedicel long. The flower tube is long, the sepals long, and the stamens are longer than the sepals. Flowering occurs from August to October.[1] [2] [3]
Pimelea sessilis was first formally described in 1988 by Barbara Lynette Rye in the journal Nuytsia from specimens collected near Kalbarri in 1985.[4] The specific epithet (sessilis) means "sessile".[5]
Pimelea sessilis grows in shrubland between Tamala Station and Yandanooka in the Avon Wheatbelt, Carnarvon, Geraldton Sandplains and Yalgoo bioregions of Western Australia.
Pimelea sessilis is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
