Eriogonum truncatum, the Mount Diablo buckwheat, is a small pink wildflower, believed to have been extinct since 1936 until its rediscovery in 2005. The species is only known to live on Mount Diablo in Contra Costa County, northern California. Mt. Diablo buckwheat is an annual plant growing between 150-750 millimetres (5. 9 in-2 ft 5. 5 in) high. It blooms with several dozen pinkish flowers, having a maroon line down the center of each petal. The flower stalks branch upward in a wishbone pattern, with flowers blooming at the joint and ends of the wishbone. The plant, an annual wildflower which dies after flowering and which is found at just one site, is still considered critically threatened. In December 2007 the Working Group seeded additional plots near the wild site.
