Description
editAstragalus bicristatus is a perennial herb sprawling outwards with stems to a maximum length approaching half a meter. The leaves are up to 14 centimeters long and are made up of very widely spaced narrow linear leaflets. The stems and foliage have sparse grayish hairs, giving them a rough texture. The inflorescence is a loose array of up to 20 pealike flowers. Each flower is between 1 and 2 centimeters long and is purple-tinted white to light greenish yellow.[3]
Its bloom period is between the months of May and August.[2]
The fruit is a hanging capsule 2 to 4 centimeters long and curved or crescent-shaped. It is fleshy when immature and leathery to woody when dried.[4]
