of larger growth. Common in canons where there is plenty of shade 

 and moisture. 



Gymiwgramine triangularis, Kaulf. Commonly known as "Gold 

 backs," from the golden color of the spores. Grows in crevices of 

 rocks and is a great favorite in cultivation. 



NotJiolacna Newberryi, Gray. Sometimes called "Silver Fern," as 

 it is very white and tomentose underneath. It grows from four to six 

 inches high on the mountain side. 



AdianttiDi emarginatinn, Hook. Larger than ^. Capillus- Veneris, 

 L. , and with the segments of the fronds not incised. Common in 

 canons in damp places. 



\]'oodwardia radicans. Smith. A very imposing fern growing 

 from four to six feet high in large clumps. Common along streams in 

 shady canons. —Jos. F.James, Cincinnati. 



"Systematic Fern-List." — A classified list of the known ferns 

 of the United States of America, by Daniel C. Eaton, New Haven, 

 Conn. September 7, i88<>. First edition. 



This neat and timely "Fern-List," by the author of the "Ferns 

 of North Ame ica," is most welcome, and will be warmly received by 

 all fein students. The species and genera are arranged in tribes and 

 the geographical range noted. All the recent additions, including 

 Notholcena nivea (for which New Mexico should be added to the 

 range) and N. Lemnioni. discovered since the completion of the two 

 volumes of Ferns of North America, are given. 



The List is designed for exchanges, and will not only serve its 

 purpose admirably, but help to familiarize students with the changes 

 in nomenclature adopted by the author in his fern book, although the 

 necessity for some ^f them is certainly to be regretted. 



It was so much e isier, for example, to write Ophioglossum bul- 

 bosuni than O. crotalophoroidcs I and then Michaux's name had become 

 so well established, and was, withal, so exceedingly appropriate that 

 it seemed a pity to disturb it. But the law of priority is inexorable, 

 and we must write Walter's name whether we like it or not. It may 

 not be out of place here to state that the recent collection of two very 

 distinct forms of Asplcnium myriophyllum, by Miss Reynolds, makes it 

 almost certain that we shall have to recognize the presence of Asple- 

 nium rhizflphyllum, Kunze in Florida, and reduce rfiy?-iophylliim to the 

 rank of a variety of that species with Hooker. I have the authority 

 of Mr. Baker for saying that Miss Reynolds' two forms represent those 

 two ferns as they have them in the Kew Herbarium, thus rendering 

 this further change in our nomenclature probable. 



Hooker here, as in the larger work n ferred to, is given as au- 

 thority for Aspidium spinulosuni var dilatatum, but it appears from some 

 notes published in the Canadian Natuialisf, by D. A. P. Watt, of 

 Montreal, that Aspidium dilatatum was first reduced to a var. o{ spin- 

 ulosum under Folystichum in "Hand-book i Skandinaviens Flora," 

 p. 398, by Hartmann, and the name Aspidium spinulosuni var. dilata-
