From Wikipedia, the free encyclopedia
Eriogonum apricum is a species of wild buckwheat known by the common name Ione buckwheat. This rare plant is endemic to the Sierra Nevada foothills of California, where it is known from fewer than ten occurrences in Amador County. This plant grows on and is named for the Ione Formation, a local geologic formation of the iron-rich oxisol soil type. It is a state and federally listed endangered species. This is a small perennial herb growing in patches no more than 25 centimeters wide and tall. Its straggly erect stems are mostly naked and reddish or brown in color, and they have a few tiny, round, fuzzy leaves toward the base. Atop each thin branch of the stem is an inflorescence with minute flowers each only a few millimeters wide. There are two varieties of this plant; var. prostratum is sometimes called Irish Hill buckwheat. Threats to the survival of this species include mining, agriculture, development, and erosion.
