Scientific Name: Agalinis skinneriana
Taxonomy Group: Vascular Plants
COSEWIC Range: Ontario
COSEWIC Assessment Date and Status Change: November 2010
COSEWIC Status: Endangered
COSEWIC Status Criteria: B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)
COSEWIC Reason for Designation: A highly restricted annual species of tallgrass prairie known in Canada from only two populations in southwestern Ontario. Recent losses of subpopulations have resulted in a decline in range, habitat area and quality, and number of mature individuals.
COSEWIC History of Status Designation: Designated Endangered in April 1988. Status re-examined and confirmed Endangered in April 1999, May 2000, and November 2010.
SARA Status: Schedule 1, Endangered
Date of Listing (yyyy-mm-dd): 2003-06-05

Image of Skinner's Agalinis
Skinner's Agalinis is an annual herb which measures 10 to 60.5 cm in height. The stem is pale green and may have a few branches near the top. The leaves measure 5 to 20 mm in length and 0.5 to 1 mm in width, and have rough short hairs. The flower is bell shaped and measures 10 to 17 mm in length. The corolla of the flower is pink to white, with pale yellow lines and pale red spots; there are fine hairs on the exterior surfaces of the flower. The capsules are round; the yellow to tan seeds measure 0.5 to 1 mm in length.
Distribution and Population
Skinner's Agalinis occurs in eastern U.S.A. and in extreme southwestern Ontario. In 1987, there were 11 sites known on Walpole and Squirrel islands in Lambton County, Ontario, and one small site in neighbouring Essex County. Only five of the Lambton sites still contained specimens in 1997; the current status of the Essex site is unknown.
Skinner's Agalinis grows in dry prairies, open woods, rocky open glades, bluffs or pockets among sand dunes, where the soil is shallow.
In Canada, Skinner's Agalinis flowers from August to mid-September. The fruit matures in late September or October. This plant reproduces mainly through seeds.
Loss of habitat and human disturbances are the main limiting factors for Canadian populations of Skinner's Agalinis. In addition, the prairie remnants on the delta islands are subject to changes in water levels, invasion by competitive species, and changes in species composition resulting from fire suppression.
The Skinner's Agalinis is protected under the federal Species at Risk Act (SARA). More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.
The Skinner's Agalinis occurs on land belonging to the Walpole Island First Nation, which is federal land protected under SARA. It is protected elsewhere by the Ontario Endangered Species Act. Under this Act, it is prohibited to kill, harm, harass, or collect this species, or to destroy its habitat.

COSEWIC Annual Reports
COSEWIC Annual Report - 2010 - 2011 (2011-09-09)Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”. COSEWIC held two Wildlife Species Assessment Meetings during the past year assessing the status or reviewing the classification of a total of 92 wildlife species.
