172 TREES OF NEW ENGLAND. 



: 



Acer Saccharum, Marsh. , var. barbatum, Trelease. Cha: 

 acteristic trees (Cheshire County, N. H.), with small, fir: 

 deep green, three-lobed leaves, appear very distinct, but many 

 transitions are noted between this and the typical Acer 

 Saccharum. (Rhodora, III, 234.) 



Acer Sacckarum, Marsh., var. nigrum, Britton. Occasional 

 in alluvium of the Cold river (Cheshire county, N. H.). The 

 large, dark green, " flabby " leaves, with closed sinuses and 

 with densely pubescent petioles and lower surfaces, quickly 

 distinguish this tree from the ordinary forms of the sugar 

 maple. (Rhodora, III, 234.) 



Fraxinus Pennsylvania, Marsh., var. lanceolata, Sarg. 

 Common along the Connecticut at Walpole, K H. (M. L. 

 Fernald in lit., September, 1901.)
