4. ADIANTUM 



1. Adiantum pedatum var. aleuticum Ruprecht, Distrib. Crypt. 

 Vase, in Imp. Ross., p. 49. 1845. 



Type locality. — Unalaska and Kadiak.

 Peninsula, Quebec.

 138; Yosemite Valley and mountains, Torrey 597; rocks north of 

 Farewell Gap, Tulare County, 11,300 feet, Purpus 5674. 



This variety is a rare fern in the Sierra : besides the above reported

5. ASPLENIUM 



1. Asplenium filix-foemina var. cyclosorum Ruprecht ; D. C. Eaton 

 in U. S. Geog. Surv. W. 100th Merid., vol. 6, p. 331. 1879. 



Athyrium cyclosorum Ruprecht, Beitr. Pflanzenk. Russ. Reich., vol. 3, p. 41. 

 1845. 



Type locality. — " Petropawlowski ! et Unalaschka ! Kadiak!" 



Range. — Alaska to California and Arizona, east to Nebraska. 

 Siberia. 



Zone. — The few specimens seen of this fern do not warrant zonal 

 assignment. 



Specimens examined. — Glen Alpine, McGregor 172; ravine near 

 Fallen Leaf Lake, Tahoe, 6,300 feet. Smiley 364. 



The typical Lady Fern {A. filix-foemina Bernh.) is abundant in 

 moist shady places in the Transition zone of both the Sierra and the 

 Coast Range, but does not rise above that level. 



The form noted by Miss Eastwood at East Lake and other places 

 in the mountains of Tulare County and referred by her^^ to Athyrium 

 cyclosorum striatum Gilbert (List N. M. Pterid., p. 32, 1901) has 

 not been seen by me.
