S. pungens is the most common species of the genus in Missouri. The plant can be difficult to ID because it closely resembles a few more species in the state and is a variable plant. Its triangular stems and creeping rhizomes will help you begin to make an ID. Other distinguishing characteristics are best seen with a lens or dissecting microscope.
