Thelypodium milleflorum is a species of flowering plant in the mustard family
known by the common name manyflower thelypody. It is native to western North America, particularly the Great Basin
and surrounding plateau, desert, and foothill habitat, where it grows in sagebrush
and scrub. It is a biennial herb producing many erect stems, often approaching two meters in height. The stems are hairless, sometimes hollow and inflated, and often waxy in texture. The basal leaves have oblong to lance-shaped blades with toothed edges, and sometimes divided into segments. The large inflorescence
is a dense, spikelike raceme
of mustardlike flowers with white petals. The fruit is a narrow, flat silique
up to 8 to 10 centimeters long.
