BRYOPHYTES OF THE MT. GREYLOCK REGION, — III. 



A. Le Roy Andrews. 



The mountain surface still yields returns for further eflfort 

 expended, more slowly it is true, but each newly found species is of 

 proportionately enhanced interest. The species listed below were 

 collected on several trips made during the past spring and summer. 

 Special attention paid to the closely related genera, Bryum and 

 Webera, brought to light several good species, otherwise results are 

 more or less "scattering," 



Ragged Mountain is a spur of the mountain mass, of irregular 

 contour and altitude, running in a generally northerly or slightly 

 northeasterly direction, from the Bellows Pipe to North Adams, 

 forming the eastern wall of the Notch. The eastern slopes of the 

 mountain in Adams, as well as those of Ragged Mountain, show 

 several species of more or less southern tendency. The Notch is 

 perhaps in even greater degree than the Hopper, the abode of 

 surprises, generally, though not always, of northern species, the 

 isolated character of its moss and hepatic flora corresponding with 

 our knowledge of New England mountain flora generally and offer- 

 ing a hint to collectors upon other mountains. 



I again add brief notes as to altitude, distribution, etc. The 

 species not previously reported are the following: 



Musci. 



AmblystegiuM varium (Hedw.) Lindb. Decayed spot on tree at 

 middle altitude. This is of the typical form, which, as occurring 

 here and in the vicinity, generally is very distinct from the one 

 variously treated as variety or species, orthodadon, which Prof. 

 Cheney, however, considers unworthy of distinct treatment. 



Anacamptodon splachfioides (Froelich) Brid. A specimen with a 

 single capsule mixed with the last. Also on a decayed spot in beech- 

 tree at higher altitude, full-fruited. This species, though not fre- 

 quently met with, proves to be of general distribution in the vicinity. 



Brachythecium laetum (Brid.) Br. & Sch. On wet bank in Notch, 

 lower altitude.
