Text:"Cannot separate this species from A. ramosum, Beauv."
Comment:Bailey cites "Domin. Prodr. p. 62 (under Arthopteris)" [i.e. K.Domin, Biblioth. Bot. 20(85): 62 (1914)]. Bailey had apparently seen page proofs of Domin's work but Arthropteris submarginale Domin had not yet been validly published.
