Pultenaea luehmannii is a diffuse, more or less prostrate sub-shrub with slender, glabrous, trailing branches. The leaves are narrow elliptic, 5–17 mm long and 1–3 mm wide with the edges rolled under. There is an inconspicuous stipules about 1.5 mm long at the base of the leaves, and pressed against the stem. The flowers are arranged in groups of three to six. The sepals are 4–5 mm long and hairy with bracteoles about 2 mm long attached to the base of the sepal tube. The standard is yellow to orange and 7–8 mm long, the wings are yellow and the keel is dark brown. Flowering occurs from October to November and the fruit is an egg-shaped, sparsely hairy pod.

Pultenaea luehmannii was first formally described in 1905 by Joseph Maiden in The Victorian Naturalist from specimens collected in 1904 in the Grampians National Park by Herbert Williamson. The specific epithet (luehmannii) honours Johann George Luehmann.
