1902] Andrews, — Bryophytes from Mt. Greylock 29 



A LIST OF BRYOPHYTES FROM THE MT. GREYLOCK 



REGION. 



A. LeRoj' Andrews. 



Our knowledge of the distribution of bryophytes depends upon 

 collections made at points so widely separated and is, therefore, of so 

 general a nature as compared with that of the higher orders of plant 

 life that a list from a limited region may furnish something of interest 

 in the way of a comparison and possibly fill desirably an occasional 

 gap. From this standpoint the results of collecting done upon Mt. 

 Greylock during the past summer seem worthy of passing note. 

 The specimens were taken from the northern portion of the moun- 

 tain-mass, at various points in the townships of Williamstown, New 

 Ashford, North Adams and Adams, and will give at least a fair idea 

 of the prevailing species. For the sake of definiteness I will confine 

 the list to the mountain region, from brook-beds at base to its sum- 

 mit. 



Locally its mosses and hepatics are of great interest as occurring, 

 particularly in higher altitudes, in so many species not found else- 

 where in the vicinity, and several will be noticed to be uncommon in 

 the state. The mountain lacks alpine conditions and therefore alpine 

 species. Subalpine sorts are, however, well-represented, the flora on 

 the whole, as may be seen by comparison with the Vermont lists, 

 resembling in a marked degree that of the Green Mountain region of 

 that state. 



Comparatively little collecting has been done in western Massa- 

 chusetts, especially in Berkshire County. A short list of Berkshire 

 bryophytes forms a part of Chester Dewey's plant-list for the county 

 in the History of Berkshire County published in 1828. I know of no 

 later attempt to treat systematically either the mosses or hepatics of 

 the region. The same list was incorporated in Prof. Hitchcock's 

 Geological Report of Massachusetts published in 1835. 



The nomenclature of the following list follows as closely as possible 

 that of Lesquereux and James' Manual and Prof. Underwood's treat- 

 ment of Hepatics in 6th edition of Gray's Manual.
