Among my favorite plants are the quillworts, or Isoetes. Though little known outside of botanist circles, the quillworts are a fascinating and unusual family of non-flowering plants.

In California, there are a total of 6 fully recognized species of Isoetes. Three of these are aquatic plants, and must be continually submerged under water. Two are found in vernal pool systems, and are able to survive desiccation during the hot summer months. One of the species is fully terrestrial, but is still found in mostly wet habitats.
