Dryopteris sori II: D. marginalis

One more Dryopteris post tonight. This is Dryopteris marginalis, the Marginal Wood Fern, so named for the sori that are found along the margins of the pinnules, as you can see in the top two photos. D. marginalis is perhaps my favorite species in the group; its sori are beautiful and make it easy to identify, and the fronds range in hue from a bright green to an almost iridescent bluish color. The lower photos show two lovely crown-shaped specimens in dry, rocky woods atop Glass Mountain in South Carolina.
