Pultenaea costata, commonly known as ribbed bush-pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to the Grampians National Park in Victoria. It is a spreading shrub with egg-shaped to lance-shaped leaves, and dense clusters of pea-like flowers.
Description
[edit]Pultenaea 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
[edit]Pultenaea costata was first formally described in 1921 by Herbert Bennett Williamson in the Proceedings of the Royal Society of Victoria from specimens collected near Mount William.[3][4] The specific epithet (costata) means "ribbed".[5]
Distribution and habitat
[edit]This pultenaea grows on the higher parts of the northern ranges of the Grampians in central western Victoria.[2]
