198 Maxon : A new Asplenium 



Diego County, California, 1895, R. D. Alderson ; " "San 

 Miguel Mountain, San Diego County, Cal., Laura F. Kimball." 

 In herb. A. J. McClatchie, Phoenix, Arizona : " San Gabriel 

 Mountains, near Pasadena (Los Angeles County), Cal., A. Mc- 

 Clatchie."* 



■ 



In herb. Sadie F. Price, Bowling Green, Ky.: " Rancho de la 

 Nacion, near National City, Cal., 1892, L. F. Kimball." 



Its range then extends from Los Angeles and San Bernardino 

 Counties, Cal., southward into the peninsula of Lower California. 

 Miss Kimball finds it under overhanging rocks in the smaller 

 canons, mostly where there is considerable moisture, though oc- 

 casionally in situations more exposed to the sun. 



My 



excellent species by ob- 



serving several sheets of it in the National Herbarium labeled As- 



pL 



Moore. Upon examining Moore's 



figure of the variety inci$um % \ I was convinced that they were 

 by no means referable to this variety ; and a subsequent examina- 

 tion of typical incisnm contributed by Moore to the Eaton Her- 

 barium confirmed this belief. Since the Pacific coast "incisnm" 

 seems altogether distinct from any previously described species, I 



have ventured to assign to it the specific name ve$perttnum % in al- 

 lusion to its distribution on the western coast. 



The variety incisnm of Moore is nothing more than an ex- 

 tremely foliose, deeply incised form of the common maidenhair 

 spleenwort, comparable to the variety cambric um of Poly podium 

 vulgaris and like that variety always sterile. The only true in- 

 cisum I have seen from the United States is that collected by Mr. 

 C. C. Frost, near West Brattleboro, Vermont, in 1874, fronds of 

 which are preserved in the Eaton Herbarium and in the private 

 herbarium of Dr. A. J. Grout. They agree closely with typical 

 material of incisnm and are not to be distinguished from it. Mr. 



A. A. Eaton has sent me specimens of A. Trkkamanes, collected 

 in Tennessee by Mr. J. H. Ferris, which show considerable ap- 

 proach toward incisnm, but which, together with some fronds from 

 Bethany, West Virginia, collected by Mr. G. Guttenberg in 1877, 

 and preserved in the Eaton Herbarium, are merely incised forms 

 of typical A. Trichomancs.
