Partly because of their grace and beauty, and partly because of the small number of species in any given locality and of their singular mode of growth and development, this group of plants has, to me, for many years been of more than common interest. Muscatine County is honored with about twenty-two species of ferns. As a rule these plants seek damp and shaded spots, and it would seem as if some of them will not thrive unless certain conditions of soil, water and exposure are secured. Hence, a rough, rocky region, with springs and more or less swampy ground would, most likely, be rich in individuals and in species of this interesting family.
