This species was first described in 1852 by Nikolai Turczaninow who gave it the name Thryptomene obovata in the Bulletin de la Classe Physico-Mathématique de l'Académie Impériale des Sciences de Saint-Pétersbourg from material collected by James Drummond.[2] [3] In 1985, John Green transferred the species to Micromyrtus as M. obovata .[4] The specific epithet (obovata) means "inverted egg-shaped", referring to the shape of the leaves.[5]
Micromyrtus obovata grows on hills, slopes and flats between Wubin, Lake Grace and Southern Cross in the Avon Wheatbelt, Coolgardie, Esperance Plains, and Mallee bioregions of south-western Western Australia.
