It is a low, cushion-like shrub with overlapping, keeled, linear leaves and small pink flowers arranged singly in upper leaf axils.

Micromyrtus blakelyi is a spreading, cushion-like shrub that typically grows to a height of 30–60 cm (12–24 in), its young branches densely woolly-hairy.

The flowers are more or less sessile and arranged singly in upper leaf axils, forming loose clusters near the ends of branches with bracteoles at the base.

[2][3][4][5][6][7] Micromyrtus blakelyi was first formally described in 1983 by John Green in the journal Nuytsia from specimens collected by Erwin Gauba[note 1] between Hornsby and Gosford in 1958.

[3] This species grows in shallow depression in sandstone rocks in shrubby woodland near the Hawkesbury River, from Maroota to Cowan, north of Sydney.
