In Mackenzie’s exhaustive treatment of the Cariceae in North American Flora 18: 1-478, there are sixty four species of Carex of which Kentucky specimens are stated to have been examined. Below are listed seventeen species of Cariceae (Cymophyllus and 16 Carex) not definitely referred to Kentucky by Mackenzie. Some of these have been found in Kentucky previous to the writer’s collections, but are included here for convenience in assembling a list of Carices of Kentucky.
