Physaria fendleri is a species of flowering plant in the family Brassicaceae known by several common names, including Fendler's bladderpod, popweed, and lesquerella.
Physaria is a genus of flowering plants in the family Brassicaceae. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy annual and perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name.
Physaria chambersii is a species of flowering plant in the family Brassicaceae known by the common name Chambers' twinpod. It is native to the southwestern United States, where it grows in desert woodland and plateau habitat. It is a perennial herb growing from a taproot and producing a clumpy rosette of stems up to 15 centimeters long, growing erect and falling over in fruit. The plant is covered in a silver-white coat of hairs. The leaves in the rosette are rounded to oval, up to 6 centimeters long by 2 wide, and smaller, spoon-shaped leaves are located along the stems. The inflorescence is a raceme of four-petalled golden yellow flowers. The fruit is an inflated pod which may be over a centimeter long. It is notched and divided into two chambers, each containing 4 seeds.
Paysonia perforata, known by the common name Spring Creek bladderpod, is a rare species of flowering plant in the mustard family.

Physaria obcordata is a rare species of flowering plant in the family Brassicaceae known by the common name Dudley Bluffs twinpod. It is similar in appearance to the more common Piceance twinpod, but can be distinguished by looking at the leaves through a hand lens. The Piceance twinpod, Physaria acutifolia has stellate hairs when viewed through a hand lens while Physaria ocordata has markings that look like a satellite dish, or a circle with a dot in the middle. It is endemic to Colorado, where it is found only in the Piceance Basin in Rio Blanco County. It is threatened by the loss and degradation of its habitat. It is a federally listed threatened species of the United States.

The basal leaves are up to 6.5 centimeters long and sometimes toothed, and there are smaller leaves higher on the stem. The inflorescence is a raceme of flowers at the tip of the stem. The mustardlike flower has four orange to bright yellow petals each up to a centimeter long. The fruit is a plump, hairy, rounded capsule containing flat orange seeds.
Leavenworthia crassa is a species of flowering plant in the mustard family, Brassicaceae, known commonly as the fleshy-fruit gladecress.

Physaria kingii is a species of flowering plant in the family Brassicaceae known by the common name King bladderpod. It is native to western North America from Utah to Baja California, where it grows in dry and rocky habitat, such as deserts and adjacent mountain slopes.
