SHORTER NOTES 



JuNGERMANNiA IN New HAMPSHIRE. — All four species of the 

 genus Jungertnannia hitherto reported from New England have 

 been collected by the writer at Waterville, New Hampshire, 

 during 1906 and 1907. This, while a non-calcareous region, is 

 well supplied with all the bryophytes to be expected there. 



The commonest is J. lanceolata L., reported from all the New 

 England States. By living on rocks or humus, it is independent 

 of the underlying geological formations ; but the other three are 

 rock- and talus-growing plants, and avoid limestone at that. As 

 J. lanceolata is unmistakable when fertile, it is herewith dismissed. 



New Hampshire is the only state from which the subalpine/. 

 sphaerocarpa Hook, is reported. It is found at Waterville on wet 

 granite ledges, facing north, at 2,500 feet altitude, and with 

 abundant perianths. It is a delicate plant, of a clear light-green, 

 without much trace of purple ; and it grew mixed with Marsu- 

 pella einarginata (Ehrh.) Dum., Lophozia alpcstris (Schleich.) 

 Evans, etc. 



The other two species were on granite rocks in Mad River, at
