Iliamna remota Greene (Kankakee mallow, Malvaceae) is listed as endangered in Illinois and is endemic to Langham Island in the Kankakee River, Kankakee County, Illinois. Information on ways to break seed dormancy of I. remota would be useful for restoration and management. The purpose of this study was to determine if hot water at different temperatures and for different lengths of time would break seed dormancy. Seeds were dipped for 60 seconds into water at 70, 80, 90 or 100 degrees C with 22 degrees C dips as a control. In another trial, seeds were dipped into 80 degrees C …
