''Trifolium stoloniferum'', the running buffalo clover, is an endangered species of perennial clover native to the eastern and midwestern United States. From 1940 to 1985 it was believed to be extinct until two populations were discovered in West Virginia. Since then, more populations have been found in the US but it still remains one of the most imperiled plants in North America. ==Description== This plant has erect, unbranched flowering stems, typically tall. The apex of the stem is topped by a round flower head, subtended by two leaves. These apical leaves are typically larger than those found on stems without flowers. The flower heads are white, sometimes tinged with purple, and 2–2.5 cm diameter. Like other clovers, Running Buffalo Clover has leaves divided into three leaflets. It sends out long creeping runners (stolons) from its base, which grow along the ground and take root. The stems and leaves are hairless. It flowers from mid-May to June and fruits in July.
