Micromyrtus blakelyi is a spreading shrub in the myrtle family. It is found near the Hawkesbury River, north of Sydney. It usually grows in depressions and crevices in Hawkesbury Sandstone. The shrub grows to a height of 0.3 to 0.6 metres, and has a cushion-like appearance. Flowering occurs from August to October (early Spring). It is a rare plant, listed in New South Wales as vulnerable. The shrub was first collected by botanists in 1958, and it was named in honour of William Faris Blakely. * See also another rare related Sydney species: Micromyrtus minutiflora
