It is an erect, short-lived perennial shrub with lyrate or lobed leaves, egg-shaped to elliptic in outline with toothed edges, and leafy racemes of bluish-purple flowers.
Goodenia macmillanii is an erect, short-lived perennial shrub that typically grows to a height of . The leaves are lyrate or lobed, egg-shaped to elliptic in outline with toothed edges, long and wide on a petiole long.

Goodenia macmillanii was first formally described by Victorian Government Botanist Ferdinand von Mueller in 1859 in Fragmenta Phytographiae Australiae, from specimens collected near the "McAllister River".[4] [5] The specific epithet (macmillanii) honours Gippsland pioneer and explorer Angus McMillan.[3]
Pinnate goodenia grows on rocky slopes in the valleys of the Macalister, Snowy and Deddick Rivers.[6]
The species is listed as "vulnerable" on the Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria.[7]
The species may be grown in shade or sun, and is somewhat drought tolerant though it performs best in moist situations. It can withstand light to moderate frosts and prefers a sandy loam although it may be grown in rocky or clay-based soils. It may also be grown as a container plant in standard potting mix. Plants may be propagated by division.[3]
