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-richoxisol soil type. It is a state and federally listedendangered 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 aninflorescence 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.External links
