Ball Department of Botany, Erindale College, University of Toronto, Mississauga, Ontario L5L 1C6 Ball, Peter W. 1978. Occurrence of Carex carevana in Canada. Canadian Field-Naturalist 92(2): 197-198. Carex careyana is a rare sedge in Canada. It was first recorded by Klugh (1906) from Guelph, Ontario. MacKenzie (1935) and Soper (1949) also mentioned the occurrence of this species in Ontario, but both of these records seem to have been based on the specimens collected by Klugh. The species has also been recorded from one locality in southern Quebec (near Sweetsburg) cf., Raymond 1941), but no confirmatory specimens have been seen, and Rouleau (1946) throws some doubt on its occurrence in that province. Boivin (1967) excluded C. careyana from the Canadian flora, but in a personal communication (1976), he stated that he has subsequently traced ma- terial collected by Klugh in 1905 and 1906 in the her- baria of Queen's University, Kingston (QK) and the University of Guelph (OAC). None of these specimens give any precise details of the locality, other than Guelph, but a previously untraced specimen in the herbarium of the National Museum of Canada (CAN) gives the location as Dairy Bush, Ontario College of Agriculture, Guelph. In addition to the locality discovered by Klugh the species has previously been collected from two other localities in southern Ontario. Curiously enough, both collections were made by A. A. Wood in Middlesex County in 1934. One, correctly determined as C. careyana, was from Strathroy, the other from Poplar Hill about 10 km east of Strathroy. This second specimen was originally determined as C. platyphylla, but this determination was corrected by Boivin in 1974. Both specimens are preserved in the herbarium of the Biosystematics Research Institute, Ottawa (DAO). This investigation was prompted by the discovery of a fourth locality for this species in Ontar
