REPORT OF THE STATE BOTANIST I9II 21 



SPECIES NOT BEFORE REPORTED 



Acer carolinianum Walt. 

 Troupsburg, Steuben co. May. This species is readily distin- 

 guished from Acer rub rum L., the red maple, when in fruit. 

 The wings are nearly parallel or convergent, but in the red maple 

 they are divergent. They are also nearly or quite fully developed 

 when the leaves are yet partly expanded. The leaves are usually 

 only three lobed and are more hairy, specially beneath, than in the 

 red maple. On account of the three lobed leaves it was named 

 Acer rubrum var. t r i d e n s in Wood's Class Book of Botany 

 It has generally been neglected by botanists but it certainly seems 

 worthy of recognition. The station here reported is the only one in 

 our State known to me and is north of its previously recorded range.
