Underwood : A new Adiantum from New Mexico 47 



not seen in plants collected in Texas by Newberry and by Holden 



(C), nor in those collected by Hall (Y), nor in those collected 



in southern California by Stout (Y), and by Thayer (U), nor in 



those collected by MacDougal in Arizona in 1891 (U), which 



agree more nearly with the common European forms of A. capil- 



lus-veneris. Professor Earle has fortunately collected this fern in 

 some quantity. 



Columbia University, i Jan. 1900.
