Calytrix fraseri was first formally described in 1834 by the botanist Allan Cunningham in 1834 in the journal Botanical Magazine, from specimens colleced by Charles Fraser near the Swan River.[3] [4] The specific epithet (fraseri) honours the collector of the type specimens.[5]
Pink summer calytrix grows on sandplains, coastal dunes and granite outcrops between Horrocks Beach and Bunbury and inland as far as Kondinin in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australia.
