About Astragalus didymocarpus Hook. & Arn.
Astragalus didymocarpus Hook. & Arn. is a slender, hairy annual herb. It can grow erect to around 30 centimeters (12 inches) tall, grow drooping, or spread flat on the ground to form a spreading clump. Its leaves reach up to 7 to 8 centimeters (2.8 to 3.1 inches) long, and are composed of narrow to oblong leaflets. The inflorescence is a cluster of up to 30 purple-tinted white flowers, each less than 1 centimeter (0.39 inches) long. The inflorescence is covered in long black and white hairs. The fruit is a small, spherical legume pod that dries to a stiff, papery texture. In the Mojave Desert, this plant is foraged by desert tortoises (Gopherus agassizii), and makes up a significant part of their diet.
