Quillwort (Lycophytes)
Isoetes is closely related to plants that made most of our coal. It has underground corms, organs with a unique ‘fuzzy morphology’ which are both root- and shoot-like. Sacs at the bottom of each quill-like leaf produce large female and small male spores. Isoetes is usually found among stones at the bottom of clear ponds.
