visited by botanists, lies within the area of the shale barrens, 

 which possess the most interesting portion of the state's flora, 

 including many endemics. These have since been discovered 

 in more remote districts, 100 miles or more from the original 

 locality. 



A number of varieties and forms of common plants were 

 described by Dr. C. F. Millspaugh from Morgantown during 

 the tenure of his stay there as Botanist of the Agricultural 

 Experiment Station. The types of these plants are, for the most 

 part, filed in the Herbarium of West Virginia University. A 

 few appear to have been lost in the various vicissitudes to which 

 the herbarium was exposed before it reached its present per- 

 manent quarters in Science Hall. 



Under each species in the list, the author has attempted to 

 give, usually quoted verbatim, the type locality, type number, 

 date of collection, and any other important data. Where pos- 

 sible the accepted name for each species is given when the name 

 listed has been found to be a synonym. Unless otherwise stated 

 the name is to be taken as representing a good species. 



Forty-five species, varieties and forms are here listed: 



^1. Polypodium vulgare forma hiserrata Millsp., Prel. Cat. Fl. 

 W. Va. p. 479, 1892. "A form found upon mossy boulders 

 along the Blackwater Fork of Cheat; with regularly doubly- 

 serrate divisions of the thinnish fronds," Millspaugh. 



y 2. Polypodium vulgare var. deceptum Maxon, Proc. Nat. Mus., 

 / 23:628. 1901. "Type in the U.S. National Herbarium. Smith- 

 sonian Institution, collected by E. L. Morris, No 1215, on 

 rocks along the Guyandotte River below Baileysville, Wyo- 

 ming County., W. Va.,. Alt. 1100-1250., August 13-19, 

 1900. This fern has already been briefly characterized by 

 Dr. Millspaugh as Polypodium vulgare forma hiserrata. The 

 name, biserratum being already preoccupied by a Mexican 

 fern it becomes necessary, in referring to the West Virginia 

 plant, to substitute a new name." (P. virginianum forma 

 acuminatum (Gilbert) Fernald, Rhodora 24: 141. 1922, fide 

 Wherry ms.).
