Sphagnum rentrvnm, Beauv. (S. intermedium^ Hoffm. of Manual.) 

 In similar situations. 



Sphagnum rigiduw, Sch. In similar situations. 



Sphagnum /enerum, (Aust.) Warnst. In similar, more open place. 

 Distinguished from the closely-related S. aeutifolium by the invo- 

 lute-pointed stem leaves, fibrillose throughout, with divided utricles, 

 and the narrow pores of the backs of leaves. Hitherto reported 

 only from New Jersey and Connecticut. 



ThuiJiitm scitum, (Beauv.) Aust. Stones and base of trees in woods, 

 near base in New Ashford. 



Hepaticae. 



Aneura latifrons, Lindb. On decayed logs at middle altitude. 



Cephalozia curvifolia, Dumort. Rather common on decayed wood at 

 various altitudes. Most abundant and well-fruited at middle alti- 

 tude with last. 



Cephalozia (/h<arieata, Dumort. This species was found in clefts of 

 dry rock at base of mountain, in Hopper. 



Cephalozia multiflora, Spruce. On decayed wood at various altitudes. 

 Especially common about the summit, where it occurs mixed with 

 other hepatics and mosses, and generally sterile.

 per, also on rock in woods of lower slope. 



Jungermantiia ineisa, Schrad. On ground near summit.

 tudes, with Cephalozia curvifolia. 



Jungermannia ventrieosa, Dicks. With Dicranum fuseeseens on de- 

 cayed stumps, just below the summit. The masses of minute 

 bodies borne on the tips of the leaves gave the mat of plants a 

 quite characteristic glaucous-green appearance. 



Marsupella emarginata, Dumort. On wet rocks, frequently in brook- 

 beds, at higher altitudes. 



Radula eomplanata, Dumort. On rocks and earth at base of moun- 

 tain in New Ashford, Williamstown, and North Adams.
