Bladderpod Mustard or Gordon's Bladderpod

Bladderpod mustard is also known as Gordon's bladderpod (lesquerella gordonii).

The USDA website shows that it can be found in Arizona, New Mexico, Texas, Kansas, Oklahoma and Virginia. We found it along the I-10 freeway in Arizona outside of Quartzite.

It has a yellow flower with four rounded petals,

followed by round, green to reddish, pea-sized seedpods with slender, pointed tips.

The leaves are grayish green and covered with fuzzy hair. The stems are also hairy.
