THE FERN BULLETIN 



have been passed over as an extreme form of the spe- 

 cies, but found growing in Colorado where, so far as 

 known, A. Bradleyi does not occur the conclusion may 

 be reached that it is entitled to specific rank and 

 this is helped out by the difference in size and the gen- 

 eral outline of the fronds, though there are many that 

 insist that it is merely a form of A. Bradleyi that has 

 been produced by the changed conditions under which 

 it grows. In order that the problem may be better 

 judged we present herewith a drawing of the fern, the 

 first, so far as we are aware, that has been published. 



The most noticeable characteristics of the fern are 

 the small size of the fronds, the triangular blades 

 nearly twice pinnate, the triangular pinnae, and the 

 short dark stipes. The rachis is generally pale green 

 and the rootstock clothed in dark brown hairs. 



Viewed by itself we are inclined to call it a good 

 species but we confess to a strong desire to know what 

 would happen if plants were grown from its spores and 

 given more suitable surroundings. Our frontispiece 

 is from specimens collected at the type locality by Prof. 

 E. Bethel and kindly communicated by Mr. W. A. 

 Povser. The illustration is about natural size. 



NOTES ON THE PTERIDOPHYTA OF SOUTHERN 

 NEW BRUNSWICK. 



BY A. B. KLUGH, M. A. 



The region covered by these notes is the St. Croix 

 River Valley and the territory in the vicinity of Pas- 

 samaquoddy Bay in Southern New Brunswick. The 

 greater part of the region was originally covered by 

 a coniferous forest formation consisting largely of 

 Picea Canadensis (white spruce) with which Betula 

 alba papyrifcra (paper birch) was intermingled. At
