About Thelypodium crispum Greene ex Payson
Thelypodium crispum is a species of flowering plant in the mustard family, commonly called crisped thelypody. It is native to the mountains and plateaus of Nevada and eastern California. It grows in areas with mineral-rich, alkaline soils, such as the margins of hot springs. This plant can be an annual, biennial, or short-lived perennial herb. It produces an erect, branching stem that reaches a maximum height between 10 centimeters and 1.2 meters. Its thick, waxy basal leaves are usually divided into lobes, while leaves growing higher on the stem are typically simple and have bases that clasp the stem. The inflorescence is a dense, spikelike raceme holding many white, greenish, or lavender flowers with very crinkly petals. The fruit is a cylindrical silique 1 to 2.5 centimeters long that contains several seeds.
