Description
editPultenaea costata is a spreading shrub that typically grows to a height of up to 1 m (3 ft 3 in) and has stems that are hairy when young. The leaves are egg-shaped to lance-shaped, 7–15 mm (0.28–0.59 in) long and 2–5 mm (0.079–0.197 in) wide tapering to a sharp, down-curved point and with dark brown stipules about 7 mm (0.28 in) long at the base. The flowers are arranged in dense clusters of five to eight surrounded by bracts about 8 mm (0.31 in) long with two points on the tip. Bracteoles about 8 mm (0.31 in) long are attached to the base of the sepal tube. The sepals are about 9 mm (0.35 in) long and joined at the base, the lobes hairy. The standard petal is 13–15 mm (0.51–0.59 in) wide and the ovary is covered with long hairs. The fruit is a pod surrounded by the remains of the sepals.[2]
Taxonomy and naming
