Description

Grevillea sessilis is shrub or small tree that typically grows to a height of 2–6 m (6 ft 7 in – 19 ft 8 in). Its leaves are 50–160 mm (2.0–6.3 in) long and pinnatipartite with 5 to 18 narrowly egg-shaped or oblong lobes 25–80 mm (0.98–3.15 in) long and 4–12 mm (0.16–0.47 in) wide. The flowers are arranged in cylindrical clusters along a rachis 50–180 mm (2.0–7.1 in) long, the pistil 17.5–31 mm (0.69–1.22 in) long. The flowers are white with a creamy-white or yellowish green style with a green tip. Flowering occurs from April to December and the fruit is a hairy follicle 12.5–15 mm (0.49–0.59 in) long.[2]
