Description
editPultenaea divaricata is an erect shrub that typically grows to a height of up to 1 m (3 ft 3 in) and has stems that are more or less glabrous. The leaves are arranged alternately, linear to needle-shaped, 5–12 mm (0.20–0.47 in) long and about 0.5 mm (0.020 in) wide with a groove along the upper surface. The leaves are densely covered with small pimples and there are stipules about 2.5 mm (0.098 in) long at the base. The flowers are arranged in dense clusters of on the ends of branchlets with bracts about 2.5 mm (0.098 in) long. The flowers are 5–10 mm (0.20–0.39 in) long and sessile or on pedicels up to 0.5 mm (0.020 in) long with oblong bracteoles about 2 mm (0.079 in) long attached to the sepal tube. The sepals are 2–5 mm (0.079–0.197 in) long, the standard petal and wings are yellow to orange with red markings and the keel is yellow. The ovary is hairy and the fruit is a flattened pod about 5 mm (0.20 in) long.[2]
