14 THE WEST VIRGINIA FLORA 



As in the preliminary catalogue, all species that have been 

 described from known West Virginia types are republished in full. 



SPECIAL FEATURES OF THE FLORA. 



The distribution of plants within the boundaries of the State 

 is wonderfully comprehensive. Canada places representatives of 

 her boreal flora upon its Alleghanian mountain tops, some that 

 have even passed by the States of New York, New Jersey, Penn- 

 vania, Delaware and Maryland in the transit ; the Southern States 

 contribute to its flora through the influence of the mysterious 

 New River on the southeast ; the great trunk lines of railway, as 

 well as the open condition of the western border line along the 

 Ohio River, give entrance to individuals of a migratory character 

 from the Western Plains ; and from some not readily accountable 

 reason many Eastern forms, and even coast line species stray 

 within its limits. 



Of the noteworthy species we connect in Anemone trifolia, 

 L., Canby's and Curtiss' Virginian stations with Knipe's Penn- 

 sylvanian, and that in a direct and sequential manner through 

 the State. Our elevations for this species range from 850 to 

 2,300 feet. Trautvetteria Carolinensis (Walt.), Vail, is to be 

 found along all such mountain rills as are deeply shaded, at alti- 

 tudes above 1,000. We extend the Manual distribution of Caltha 

 palustris, L., southward nearly one degree, by finding it quite 

 plentiful in the mountains of Randolph County, where Isopyrum 

 trifoliatum (L.) Britt., keeps it company. Helleborus viridis, L., 

 has its most western station on the north branch or the Potomac 

 River, in Hardy County, whence it was first reported to Dr. Gray 

 by Dr. Gamble, of Moorefield. Aconitum uncinatum, L., is at 

 home all along the banks of Cheat River, at altitudes varying 

 from 780 to 3,550 feet. Both species of Actaea are to be met 

 with on the higher Alleghanies, where Cimicifuga Americana, 

 MX., is the principal representative of the tribe. 



Magnolia Fraseri, Walt., is a striking vernal feature of the 

 whole Alleghanian region, while tripetala and acuminata are 

 common. Berberis Canadensis, Mill, becomes a veritable weed 

 in many fields in the southern portion of the State, vying with 

 Pap aver dnbium, L., and Glaucmm Glauciuin (L.), Karst, in the
