shasta orthocarpus

Orthocarpus pachystachyus is a rare species of flowering plant in the broomrape family known by the common names Shasta owl's-clover and Shasta orthocarpus. It is endemic to central Siskiyou County, California, where it is so rarely seen it was thought to be extinct until 1996, when eight individuals were located. The plant grows in an isolated wilderness but since it apparently only occurs on one single hillside it is considered very vulnerable to extinction.
