Ferns from the Southwest 109 



Some recently described Ferns from the South- 

 west. 1 



WILLIAM R. MAXON. 



Rather more than a year ago, in a short article en- 

 titled "New Southwestern Ferns," 2 Professor Leslie 

 N. Goodding published descriptions of four supposed 

 new species and one new variety of ferns from Cochise 

 County, Arizona, and of one species from the State of 

 Sonora, Mexico, all of these being based upon specimens 

 of his own collecting. Recently Professor Goodding 

 has very courteously presented the type specimens of 

 these to the United States National Museum, in order 

 to render them more readily accessible to botanists 

 generally, and has also forwarded specimens of other 

 uncommon ferns from the same region. Notes upon 

 these are presented herewith. Unfortunately all of 

 those described as new by Professor Goodding actually 

 pertain to species previously recognized, though one 

 of them is new to the United States. Of the other 

 species several are of more than ordinary interest from 

 their comparative rarity.
