Tetradymia tetrameres is a species of flowering plant in the aster family known by the common name fourpart horsebrush[1] and dune horsebrush. It is native to the Great Basin, where it occurs in western Nevada and just over the border in Mono County, California. It is a plant of dry scrub and sand dunes. It is a bushy, woolly shrub with many erect, spineless branches. It is the largest of the horsebrushes, growing up to two meters in height.[2] The soft, woolly leaves are narrow and threadlike, growing up to 4 centimeters long. Shorter leaves occur in clusters around the primary leaves. The inflorescence bears 4 to 6 flower heads which are each enveloped in four or five woolly phyllaries. Each head contains up to four or five light yellow flowers each around a centimeter long. The fruit is a hairy achene which may be up to a centimeter long, including its pappus of long bristles.
