Isoetes acadiensis, Acadian quillwort, grows in shallow, slightly acidic, slow moving lakes and streams in the North-Eastern USA and Eastern Canada. It has skinny, narrow leaves that grow up to about 8 inches long. Acadian quillwort produces spores, not seeds, on a whorl of specialized leaves at the base of the plant that have a net-like texture on their surface. Acadian quillwort is of conservation concern because it is known from only 26 sites. Because of this is considered Near Threatened by the IUCN Red List Standards.
