Micromyrtus placoides is a species of the flowering plant in the family Myrtaceae and is endemic to the inland areas of Western Australia.

The sepals are egg-shaped, 0.5–0.6 mm (0.020–0.024 in) wide and green with deep reddish-brown to white edges.

The petals are white, broadly egg-shaped with the narrower end towards the base and about 2 mm (0.079 in) long.

[2][3] Micromyrtus placoides was first formally described in 2006 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Malcolm Eric Trudgen near Tallering Peak in 1978.

[2][3] Micromyrtus placoides is listed as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
