Asplenium nephelephyllum Copel. Phil. Journ. Sci. Bot. 9: 440. 1914. Copeland's specimens of A. nephelephyllum (Faurie 266 from Waimea, Kauai) match the type of A. dissectum Brack. [i.e., A. schizophyllum] very well. His concept of A. schizophyllum, as evidenced by specimens so named in his herbarium, evidently is based on plants which I would refer to A. sphenotomum, and those which he calls A. sphenotomum I would call A. sphenotomum var. connectens, i.e. plants merely bipinnate-pinnatifid rather than tripinnate. The true A. dissectum is quadripinnate, with monosorous ultimate segments and dareoid sori. It is known only from Kauai and is evidently of very restricted distribution.
