In the preparation of this list I have consulted various local floras and other reports of the State, especially Paine’s “Catalogue of Plants Found in Oneida County and Vicinity;” the Annual Reports of the State Botanist, “The Flora of the Upper Susquehanna,” and the files of the Fern Bulletin. I have also been favored with many notes from the State Herbarium sheets by Professor Peck himself; while my own herbarium and that of Dr. J. V. Haberer, of Utica, have been exceedingly useful in fixing definite localities. The plan I have followed is to include along with the species only such varieties as seem to be most important and distinct. Mr. Bush in _The Torrey Bulletin_ for June, 1903, enumerates 59 species and varieties of ferns found in Texas. This compares well with our list of 64 species and varieties in New York State, of which only 18 of these are common to both States. Mr. Reverchon’s list for Texas, published in the Fern Bulletin, April, 1903, gives 51 ferns and 15 allies, or 66 in all. The present list includes 53 species and 12 varieties of ferns, and 23 species and 7 varieties of fern allies. If we take Bush’s ferns and Reverchon’s allies, there are 74 species and varieties known in Texas, or 20 less than I have enumerated in New York. Ophioglossaceae. _Botrychium lanceolatum_ Angs. Open upland woods in the eastern part of State. Not reported from western part. Scarce. _Botrychium matricariaefolium_ A. Br. In same localities with _B. lanceolatum_, but more plentiful. _Botrychium obliquum_ Muhl. Grape fern. Abundant in pastures and woodlands, especially in the central part of the State. _Botrychium obliquum dissectum_ Clute. In similar places with _B. obliquum_ and always associated with it. Frequent. _Botrychium obliquum f. elongatum_ Gilbert & Haberer. Scarce in pastures, eastern New York. _Botrychium obliquum Habereri_ Gilbert. Scarce. Mohawk Valley, Catskill Mts., and probably occasional elsewhere. _Botrychium obliquum intermedium_ Clute. Pastures. Occasional in the eastern part of the State. _Botrychium obliquum matricarioides_ Gilbert. Beaver Lake. Lewis Co.; Whitestown: _Gilbert_. I have seen no other specimens from this State, but Dr. Underwood cites “Northern New England and New York.” (_Osmunda matricariae_ Schrank.) _Botrychium obliquum Oneidense_ Clute. Pastures and open woods. Occasional. _Botrychium obliquum tenuifolium_ Gilbert. Field near top of mountain. Shandaken, Ulster Co., _Mary F. Miller_. As I possess tracings of Dr. Underwood’s type specimens of B. _tenuifolium_ Und., I am able to say that these specimens from Shandaken match the tracings completely. (_B. tenuifolium_ Und.) _Botrychium Onondagense_ Underwood. Within a radius of five miles from Syracuse. The stations there are the only ones known in the State. _Botrychium simplex_ E. Hitchcock. Damp meadows and sandy swamps in Central and Northern New York. Also Wading River. L. I., _E. F. Miller_.
