THE CANADIAN NATCRALIST. 



[Sept. 



Woodsia Peruviana, shonld Chas. Wright's no. 2120 prove to be 

 that species, and a new Asplenium recently found by Prof. 

 Bradley in Tennessee. 



Mrs. Ly ell's third division, embracing all North America to the 

 west of the Rocky Mountains and north of Mexico, is well sepa- 

 rated into a botanical area, but, considering its extent and variety 

 of climate, its fern flora is small though in many respects pecu- 

 liar. Mrs. Lyell enumerates sixty species which number must, I 

 fear, be considerably reduced, inasmuch as a great part of the 

 range of mountains known as Sierra Madre is in (old) Mexico, 

 not in New Mexico, and while such States as that last named and 

 Colorada are common to both second and third areas, others, such 

 as Texas, Kansas, Missouri, and Nebraska, are wholly in the 

 second. The omissions should probably be as follows : — 



A. The eleven species above enumerated as belonging to the 

 second area not beina; known to occur on the west side of New 

 Mexico. 



B. Eight species not known on the west coast further north 

 than Mexico proper : — 



Adiantum Capilus-veneris (which, 

 however, occm*s on the east 

 side from Alabama south- 

 ward), 



Cheilauthes Seemanni 



microphylla (there is a 



Cheilanthes viscosa, 

 Polypodium Madrense, 

 Gjmnogramme tartarea, 



podophylla, 



Acrostichnm conforme. 



Kew tradition that this species 

 occurs in Texas, hut it needs 

 confirmation), 

 A few species should be added, some of which I enumerate :■ 



i^ephrodium fragrans (X. ^. 



America, Seemann), 

 dilatatum, (same locality 



and collector). 



Cheilanthes argentea (said to have 



been collected by a Russian 



botanist in Alaska), 

 Xewberrii Eaton (San Diego, 



Dr. Newberry and Prof.Wood), 

 Pellaea ( Sierras, 1869, Prof. 



Bolander — probably a new 



species). 



The scanty fern flora of the west coast may be seen from 

 the following list copied from " A Catalogue of the Plants of San 

 Francisco," by H. N. Bolander, 1870, which is said to include 

 all the ^' species found about a hundred miles north and south of 



San Francisco, and as far east as Mount Diablo " : —

 Californicum,
