Taxonomic CommentsAll Isoetes species are quite grass-like, with numerous very slender and grass-like leaves growing from a common base. Most importantly, they are swollen at the base, where the megaspores are present, the key structure for separation of species. The leaves are terete (rounded) and hollow. For identification, see the key in Weakley (2018).
