Polyctenium fremontii

Polyctenium fremontii, the desert combleaf, is a small and compact plant native to the western United States. It is named both in English and Greek for its deeply lobed leaves, which almost appear to be pinnately compound. It takes the other portion of its scientific name from John C. Frémont. Leaves have forked hairs, and the distal end of the leaf often has a single hair at the very tip. As is characteristic of the broccoli family, the white flowers have four petals in the shape of a cross. The flowers appear in clusters at the ends of the stems. This plant is among the first plants of sagebrush country in the inland western U.S. to bloom in spring. It is found on the banks of seasonal streams and similar places. ...read more on Wikipedia.
