the additional discovery of Gymnogramme triangularis^ Kaulf., and 

 Aspidiiim Filix-mas^ Swz., by the same indefatigable collector. The 

 first was collected in April on the Santa Catalina, and the last on 

 Mt. Washington, in the Santa Rita Mountains, in June, 1881. 



This discovery of A. Filix-mas so near to California ren- 

 ders its presence in that State probable, and will encourage Califor- 

 nia botanists to search for it. Some forms of A, rigidum^ van 

 argutum run very near to, and have frequently been mistaken for 



it, but no authentic specimens have as yet been received from Cali- 

 fornia. 



The species is most readily distinguished from argutum by the 

 character of the serrated margins, these never being spinulose as in the 

 latter species, which resembles A, spinulosum in this respect more 

 than it does Filix-mas, 



The under surface is usually more chaffy in Filix-mas than in ar- 

 gutum^ the laminae narrower below, and the scales at the base of the 

 stipes more or less ciliate-toothed, as pointed out by Prof. Eaton 

 in his splendid work on our North American Ferns. 



Mr. Pringle has also collected in Arizona, besides the ferns already 

 mentioned, Notholaena Grayi, N. Lemmoni, Gymnogramme hispida^ a 

 very pubescent form of Pellaeaatropurpurea, Clieilanthcs Lindheimeri, 

 C. Fendleri^ C. Fatoni^ and others,* \vhile among his ferns from 

 Oregon and California are Polypodium falcatum^ very large forms of 

 P. Scouleri^ Phegopteris alpestris and Aspidium Mohrioides. 



The excellence of Mr. Pringle's collections is now too well known 

 to need any special commendation. He will probably make some 

 arrangement before returning to the Pacific Coast (being at Char- 

 lotte, Vermont, at present) by which those who may desire sets of his 

 ferns can obtain them. 



An unusual form of Aspleniuni ebeneum, — From Miss Kate Fur- 

 bish, of Brunswick, Me., comes a very interesting form of this spe- 

 cies, one frond, measuring about 12 inches in length by 2 in breadth 

 across the middle, and having unusually narrow, deeply-serrated pin- 

 nae, I inch long, less than \ of an inch in breadth at the base, broad- 

 ening to about 3 lines at the centre where they are still more deeply 

 serrated, the lobes again serrated, and then tapering gradually into 

 an acute tip. The pinnae are obliquely set to the rachis, and some 

 of them lose their auricled bases altogether. 



The specimen is apparently one of those variations which are not 

 likely to occur twice upon the same plant, and it does not, therefore, 

 seem worth while to give it a name. Miss Furbish is rendering a 

 splendid service to the Maine flora by a series of admirably executed 

 and accurate analytical illustrations from nature, intended to include 



K- ^^p-/^l"Sle also collected, early in 18S1, a few specimens of the Woodsia 

 which Prof. Eaton has referred to W, Mexicana, Later, Mr. Lemmon sent the 

 same ern to me with the name W Plunnncrae attached, with a request that I should 

 describe and publish it. Ihis I declined to do. If now the fern which he has 

 published as a new species m the Botanical Gazette under that name is the same 

 plant, thenit is to be seriously challenged, and I do not believe it will stand The 

 ^^-m^ Woodsia had previously been collected by Mr. Rusby, Mrs. Ba-r Dr Palmer 

 and Dr. Parry. *^=»' ' x auuci
