Coryphopteris Holttum.

A genus of about 47 species (the exact size and circumscription still somewhat uncertain), perennial herbs, of Asia and e. North America (only our one species).

ID notes:Coryphopteris simulata has a superficial similarity to (and grows in similar, saturated habitats as) the more common Thelypteris palustris var. pubescens. Coryphoteris simulata has veins of the pinna-lobes unbranched, the lower leaf surface with sessile, reddish, resinous glands, and the lower surface of the costae lacking scales (vs. veins of the pinna-lobes mostly Y-forked, lower leaf surface lacking glands, and lower surface of the costae with persistent ovate scales in Thelypteris palustris var. pubescens).
