This species was first formally described by Ferdinand von Mueller who gave it the name Calycothrix creswellii in his Fragmenta Phytographiae Australiae from specimens collected by Jess Young.[2] [3] In 1893, Benjamin Daydon Jackson transferred the species to Calytrix as C. creswellii in the Index Kewensis.[4] The specific epithet (creswellii) honours C.F.Creswell.[5]
This species is found on sandplains in the Lake Barlee district in the Coolgardie and Murchison bioregions of inland Western Australia.
This species of Calytrix is listed as "Priority three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions meaning that it is poorly known and known from only a few locations but is not under imminent threat.[6]
