Physaria fendleri is a species of flowering plant in the family Brassicaceae known by several common names, including Fendler's bladderpod,[2] popweed,[2] and lesquerella.

It requires less irrigation than many other crops, due to its adaptation to life in an arid region.

[4] If the plant becomes more widely cultivated and breeding and refinement techniques are improved, the oil could be used in a number of industries, including cosmetics, coatings, plastics, and lubricants.

Breeding may also favor other characteristics in this species, such as its capacity for cultivation in other climates, male sterility to allow better control of pollination, and tolerance for a wider array of soil types.

The mash is high in protein, and has a similar proportion of various amino acids to the soybean.
