Descurainia incana is a species of flowering plant in the mustard family known by the common name mountain tansymustard. It is native to much of North America, including most of Canada, the western United States, and Baja California. It is known from many types of habitat. It is a biennial herb with a slender, greenish, often hairy stem sometimes exceeding a meter tall. The leaves are narrowly to widely oval in shape, the lower ones lobed and sometimes compound, the upper generally unlobed. The mustardlike inflorescence is a series of developing fruits beneath an elongating cluster of small bright yellow flowers. The fruit is a thin, pointed silique up to 2 centimeters long.

<i>Descurainia</i> Genus of flowering plants in the cabbage family Brassicaceae

Descurainia is a genus of plants in the family Brassicaceae which are known commonly as the tansymustards. The genus name commemorates French botanist and herbalist François Descurain (1658–1749). The plants are similar in appearance to other mustards, sending up long erect stems and bearing small yellow or whitish flowers. Many species are noxious weeds. Some species are toxic to livestock and become a nuisance when they grow in grazing fields. Plants of this genus are found worldwide in temperate regions. Descurainia sophia,, is the type species of Descurainia.

Descurainia californica is a species of flowering plant in the family Brassicaceae known by the common name Sierra tansymustard. This plant is native to western North America from California to Wyoming. It is a resident of varied habitats from mountain forest to sage scrub. This spindly mustardlike plant has a single thin stem which branches and may reach over half a meter in height. Its sparse leaves are divided into two to four pairs of dull green lobes each one to six centimeters long. The tiny bunched flowers at the tip of each stem are bright yellow. The fruit is a tiny podlike silique on a straight pedicel. Pedicels holding fruits stick out from the stem at intervals.

<i>Descurainia pinnata</i> Species of flowering plant

Descurainia pinnata is a species of flowering plant in the family Brassicaceae known by the common name western tansymustard. It is native to North America, where it is widespread and found in varied habitats. It is especially successful in deserts. It is a hardy plant which easily becomes weedy, and can spring up in disturbed, barren sites with bad soil. This is a hairy, heavily branched, mustardlike annual which is quite variable in appearance. There are several subspecies which vary from each other and individuals within a subspecies may look different depending on the climate they endure. This may be a clumping thicket or a tall, erect mustard. It generally does not exceed 70 centimeters in height. It has highly lobed or divided leaves with pointed, toothed lobes or leaflets. At the tips of the stem branches are tiny yellow flowers. The fruit is a silique one half to two centimeters long upon a threadlike pedicel. This plant reproduces only from seed. This tansymustard is toxic to grazing animals in large quantities due to nitrates and thiocyanates; however, it is nutritious in smaller amounts. The flowers are attractive to butterflies. The seeds are said to taste somewhat like black mustard and were utilized as food by Native American peoples such as the Navajo.
