Grevillea montis-cole is a straggling to open, semi-erect shrub that typically grows to high and wide, the branchlets with a few shaggy hairs. The leaves are egg-shaped, long and wide in outline and divided with 5 to 15 spreading lobes that are in turn divided with 2 to 5 lobes, the end lobes narrowly oblong, long, wide and sharply pointed. The edges of the leaves and leaflets are rolled under and the lower surface has a few woolly hairs. The flowers are arranged on one side of a rachis long and are silky- to shaggy-hairy, the
pistil long. The flowers are greenish to fawn on the outsided, dull purplish inside, with a bright red
style. Flowering occurs from October to March and the fruit is a woolly- or silky-hairy
follicle long. ==Taxonomy==
