Argyrochosma (J. Smith) Windham. Powdery Cloak Fern.
A genus of about 30 species, of s. North America, Central America, South America, and the West Indies. Traditionally treated as a component of Notholaena (or sometimes Pellaea) (Tryon, Tryon, & Kramer in Kramer & Green 1990), but best recognized as a separate genus (Windham in FNA 1993b, Windham 1987, Gastony & Rollo 1998). Molecular studies show that this group is more closely related to Pellaea and Astrolepis than to Notholaena.
ID notes: Argyrochosma has highly compound leaves (3-5-pinnate) with tiny ultimate segments (these < 4 mm wide) that may or may not have a dense covering of farina (waxy powder) on the lower surface. Our species occur on or associated with calcareous rock outcrops.
