Grevillea triternata is a dense, compact shrub that typically grows to a height of . Its leaves are divided, long, with 3 to 5 spreading lobes that are usually divided again, the end lobes sharply pointed, linear to narrowly triangular, long and wide. The edges of the leaves are usually rolled under, concealing most of the lower surface. The flowers are arranged in cylindrical or narrowly conical clusters on a rachis long, the flowers nearer the base of the rachis flowering first. The flowers are white with a cream-coloured to pale yellow style, the pistil long. Flowering occurs from August to December, and the fruit is a silky-hairy follicle long.[1] [2] [3]
Grevillea triternata was first formally described in 1830 by Robert Brown in Supplementum primum Prodromi florae Novae Hollandiae from specimens collected on mountains near Port Jackson.[4] [5] The specific epithet (triternata) means "divided into three parts", referring to the leaves.
This grevillea grows in forest and woodland in sandy soil in scattered populations in New South Wales, from the upper Hunter River and Bathurst to Coonabarabran and the Pilliga Scrub as well as on the Northern Tablelands.
