Description

This is a small perennial herb forming a thick patch on the ground, the stems reaching about 20 centimeters in maximum length. The plant is coated in dense gray to white wavy hairs. The leaves are up to 10 centimeters long and made up of several oval-shaped leaflets. The inflorescence is a projecting or upright array of 12 to 26 pealike flowers. Each flower is white, often purple-tinted or purple-veined, and between 1 and 2 centimeters long. The fruit is a curved legume pod 1 to 2 centimeters long.

It is coated in very long white hairs and dries to a thick papery texture, the beans inside rattling with the wind.[2]
