19. NET-VEINED CHAIN FERN
Woodwardia angustifolia
Swampy places from Maine to Florida, in wet woods near the coast.
Sterile fronds.—Twelve to eighteen inches high, pinnatifid with minutely toothed divisions united by a broad wing.
Fertile fronds.—Taller than the sterile, once-pinnate; pinnæ much contracted; fruit-dots in a single row each side of the secondary midribs; indusium fixed by its outer margin, opening on the side next the midrib.

The Woodwardias are associated in my mind with sea-air, pine-trees, and the flat, sandy country near Buzzard's Bay, Mass. Both species were met with in one walk not far from the shore.
