This species was first formally described in 1858 by Ferdinand von Mueller who gave it the name Calycothrix megaphylla in his Fragmenta phytographiae Australiae from specimens collected by Augustus Charles Gregory.[2] [3] In 1867, George Bentham transferred the species to Calytrix as C. megaphylla in his Flora Australiensis.[4] [5] The specific epithet (megaphylla) means 'large-leaved'.[6]
This species of Calytrix grows in heath and heathy woodland on sandstone on sandplains on the McAdam Range and in western Arnhem Land in the Northern Territory.[7]
Calytrix megaphylla is listed as of "least concern" under the Territory Parks and Wildlife Conservation Act.
