Thelypteris Schmidel

THELYPTERIS Schmidel, 1762

Rhizome dictyostelic, paleate; lamina us. pinnate, sts setose; veins all free or the lowest of adjacent segs uniting at or near sinus. Sori dorsal, us. small; indusium reniform-cordate or absent; spores bilateral. Copeland (Gen. Fil. 1947, 136) as against Alston (Kew Bull. 1932, 309) argues that Thelypteris Schmidel is invalid, and that Lastrea Bory, 1824, should be adopted.
