Description edit
Persoonia trinervis is an erect, sometimes spreading shrub that typically grows to a height of 0.3–1.8 m (1 ft 0 in – 5 ft 11 in) with young branchlets that are densely covered with greyish to rust-coloured hair. The leaves are spatula-shaped, or lance-shaped with the narrower end towards the base, 15–70 mm (0.59–2.76 in) long and 3–10 mm (0.12–0.39 in) wide with three or six prominent parallel veins and sometimes twisted through up to two complete turns. The flowers are arranged singly or in groups of up to four, each flower on a densely hairy pedicel 1–3.5 mm (0.039–0.138 in) long with a scale leaf at the base. The tepals are yellow, 8.5–16 mm (0.33–0.63 in) long and densely hairy on the outside. Flowering occurs from September to December and the fruit is a smooth, oval drupe.[2][3][4][5]
