Description

Grevillea longicuspis is a shrub that typically grows to a height of 0.6–1 m (2 ft 0 in – 3 ft 3 in), its branchlets and leaves partly covered with glandular hairs. Its leaves are egg-shaped in outline, 25–80 mm (0.98–3.15 in) long and 120–60 mm (4.7–2.4 in) wide on a petiole 5–14 mm (0.20–0.55 in) long, and are usually divided with four to eight sharply-pointed triangular teeth or lobes. The flowers are arranged in more or less spherical to oval clusters on the ends of branches or in upper leaf axils on a rachis 3–18 mm (0.12–0.71 in) long, each flower on a pedicel 2.0–3.5 mm (0.079–0.138 in) long. The flowers are red and glabrous, the style red to pinkish- or lemony-cream, the pistil 6.5–9.5 mm (0.26–0.37 in) long. Flowering occurs from August to December and the fruit is a glabrous, oblong follicle 9.5–12.5 mm (0.37–0.49 in) long.[2][3]
