Description

Astragalus bolanderi is a perennial herb producing erect, drooping, or creeping stems up to 40 centimeters long. The stems are mostly naked, with a sparse coat of long, wavy hairs and a few leaves on the upper parts. The leaves are up to 16 centimeters long and are made up of very widely spaced oval to nearly lance-shaped leaflets each up to 2 centimeters long. The leaflet has a hard midrib that ends in a point at the tip.

The inflorescence is a dense cluster of 7 to 18 pealike flowers. Each flower is between 1 and 2 centimeters long and is purple-tinted white. The fruit is an inflated, curved legume pod up to 3 centimeters long. It dries to a thick papery texture.
