Description

Synaphea divaricata is a tufted shrub with stems up to 70 cm (28 in) and covered with silky or shaggy hairs. The leaves are pinnatipartite and more or less flat, with up to three lobes, each with three to five lobes on a petiole 50–160 mm (2.0–6.3 in) long. The flowers are yellow and borne in moderately crowded spikes 10–50 mm (0.39–1.97 in) long on a peduncle 25–120 mm (0.98–4.72 in) long. The perianth has a narrow opening, the upper tepal 4.4–4.8 mm (0.17–0.19 in) long and 1.5–2.0 mm (0.059–0.079 in) wide, the lower tepal about 3.0 mm (0.12 in) long. The stigma is more or less egg-shaped with a shallow notch, thickened on the back, 0.8–0.9 mm (0.031–0.035 in) long and wide. Flowering occurs in August and September. [2] [3]
