which penetrates into the substratum and thereby protects the sporophyte 
still more effectively. With this type of perigynium the perianth is almost 
invariably absent. 
The characters noted above are usually sufficient to distinguish the gen- 
era of the Jungermanniaceae. The antheridial branches and the sporo- 
phytes occasionally yield additional characters of interest. Both of these 
structures, however, are likely to be uniform or nearly so throughout large 
groups of genera, and their characters, therefore, are more frequently tribal 
or even ordinal in value rather than generic. Under the circumstances it is 
hardly necessary to discuss them at the present time. Yale University. 
ADDITIONS TO THE BRYOPHYTIC FLORA OF WEST VIRGINIA. 
A. LeRoy Andrews. 
The “ Preliminary Catalogue of the Flora of West Virginia,” published 
by Dr. C. F. Millspaugh in 1892 (W.Va. Exp. Stat. Bull. No. 24, pp. 311-537), 
contained a list of eighty-three species and varieties of mosses and twenty- 
seven of hepatics, collected at a few points, mostly in the vicinity of Morgan- 
town, in Monongalia County. A flora of the state embodying the results of 
later collections was published by Dr. Millspaugh in collaboration with Mr. 
L. W. Nuttall, who had made extensive collections and studies about 
Nuttallburg, in Fayette County (Publications Columbian Field Museum, Bot. 
Series, Vol. 1, pp. 65-276, 1896). In this list were noted six additional species 
of mosses and five of hepaticae. For both lists, as is explained in the intro- 
duction to the latter, the bryophytes had been gathered spasmodically and 
incidentally to the investigation of other plants. 
I have seen two papers of later date listing additions to the West Vir- 
ginia flora, viz.: “Some Plants of West Virginia,” by E. L. Morris (Proc. 
Biol. Soc. Wash., Vol. XIII., pp. 171-182, 1900), and “Some New and Addi- 
tional Records in Flora of West Virginia,” by C L. Pollard and W. R. 
Maxon (Proc. Biol. Soc. Wash., Vol. XIV., pp. 161-163, 1901). Of these the 
former mentions two additional hepaticae and four mosses, two of which are 
included in the previous lists. The latter includes as new, two hepatics and 
seven mosses, one a repetition from the preceding paper. 
From collections made mostly during the fall of 1903 and spring of 1904 
in the vicinity of Morgantown I am able to add the following. Those 
recorded from near Masontown are from Preston County; the others, unless 
expressly stated, from Monongalia County. The region of Chestnut Ridge 
was most productive in bryophytes, the territory westward being very poor 
in species. Chestnut Ridge enters West Virginia from Pennsylvania, its 
direction slightly southwesterly, its altitude approximately 2,000 feet, and 
represents, so far as Pennsylvania and northern West Virginia are concerned, 
the extreme western ridge of the Allegheny system. East of Morgantown 
this ridge is cut by the valleys of Decker’s Creek and the Cheat River, and 
the richest collecting grounds are along the mountain streams tributary to 
these rivers. Especially are the steams descending the western side of the 
ridge characterized by rapid falls and the presence in their beds of many
