Description

Persoonia teretifolia is an erect, often spreading shrub that typically grows to a height of 0.5–3 m (1 ft 8 in–9 ft 10 in) with smooth bark and branches covered with greyish hairs when young. The leaves are linear, 15–70 mm (0.59–2.76 in) long, 0.9–1.5 mm (0.035–0.059 in) wide and curved upwards. The flowers are arranged in groups of up to twenty on a rachis up to 100 mm (3.9 in) long that continues to grow after flowering, each flower on a pedicel 2–6 mm (0.079–0.236 in) long with a leaf or a scale leaf at its base. The tepals are bright yellow, 9–13 mm (0.35–0.51 in) long with the side tepals asymmetrical and the lower tepal sac-like. Flowering mostly occurs from October to February.[2][3][4][5]
