have two species less of the ferns proper and two more 

 species of the fern allies. 



Our total number is the same as theirs with only 

 about half the area to collect from. If the Vermont list 

 is surprising, what shall we say for Connecticut? Of 

 the varieties omitted Nephr odium spinulosum var. dila- 

 tatum should probaby have been included, but as au- 

 thorities disagreed in regard to our material it seemed 

 better to err on the safe side and leave it out. Other 

 species that might be looked for are Asplenium Bradleyi 

 in the western part of, the state, and Schizcea pusilla in 

 sandy ground along the shore ; some species can prob- 

 ably be added also in the genus Isoetes, 



BOTRYCHIUM M ATRIC ARI^FOLIUM A. Br 



An Enquiry into the Relationships between Botrychium 

 Neglectum Wood, Botrychium Matricaria folium A. 

 Braun, and Botrychium Ramosum Ascherson. 



By George E. Davenport. 



The subject of this note involves two propositions. The 

 first relating to the identity of American and European 

 plants, and the second to the identity of Botrychium 

 ramosum and B. Matricaria folium, and the question of 

 priority of names. In regard to the first there has been 

 not the shadow of a doubt in my own mind, and I am 

 very glad that Mr. Gilbert has received an object lesson 

 from abroad that has convinced him that the two are 

 identical. (See Fern Bulletin for July, 1905.) In 

 support of this position I offer here some comparative 

 figures from specimens selected, out of many, from an 

 extensive geographical range that will, I believe, con- 

 vince the most skeptical of its truth. (See frontispiece.) 

 Now. I do not mean to assert, even with this convincing 

 evidence of their positive specific identity, that there are 

 no differences between American and European plants, 

 because precisely the same differences are to be found
