Boronia latipinna is an erect, woody shrub that grows to a height of 2.5 m (8 ft) and is hairless apart from parts of its flowers.

The flowers are pink or white and are arranged in groups of between three and twenty five or more in leaf axils or on the ends of the branches.

The groups are on a peduncle 5–13 mm (0.2–0.5 in) long, individual flowers on a pedicel of a similar length.

[2][3] Boronia latipinna was first formally described in 1957 by James Hamlyn Willis who published the description in The Victorian Naturalist from a specimen collected by Herbert Bennett Williamson on the summit of Mount Dulwil.
