Known in the Chicago Region from a single specimen collected in cindery sandy soil. Occurence in the Chicago region: non-native Etymology: Silene probably comes from the Greek word sialon, meaning saliva, referring to the sticky secretion on many of these plants. It may also have come from the word seilenos, referable to Silenus-a foam-covered, drunken character in Greek Mythology. Conica means cone-shaped.
