Tetraneuris herbacea
Also called Lakeside Daisy, Eastern Four Nerved Daisy
Tetraneuris herbacea is a rare species of flowering plant in the aster family known by the common names eastern fournerved daisy, lakeside daisy, fournerved starflower, and Manitoulin gold. It is native to and endemic to the Great Lakes region in North America, where it is present in Ontario, Ohio, Michigan, and Illinois. It is threatened by habitat destruction and degradation by several forces, including limestone quarrying, recreational activity, fire suppression, and construction. It is a federally listed threatened species of the United States and of Canada.
Tetraneuris herbacea is known from just a few natural and introduced populations. In Ontario there are about 20 populations all located at the shores of Lake Huron on the Bruce Peninsula and Manitoulin Island. In Ohio, the plant only occurs naturally in Ottawa County, where it can be found at the Lakeside Daisy State Nature Preserve, a protected area named in its honor. There is an introduced population on Kelleys Island, Ohio, as well. In Illinois, naturally occurring lakeside daisies were last seen in 1981, and today the daisies occurring there are introduced populations in nature preserves. In Michigan there is one population in Mackinac County on the Upper Peninsula, which may or may not be naturally occurring.
