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 rubrum 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. tridens 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. 



Aecidium atriplicis Shear

 A trip lex patula hastata (L.) Gray. Orient Point, Suf- 

 folk co. May. R. Latham. 



Anthyllis vulneraria L. 



Introduced. Cobbs Hill reservoir. Rochester. September. 

 Miss Florence Beckwith. Determined by P. A. Rydberg. 



Armillaria pinetorum Gill. 

 Decaying wood. North Elba, Essex co. September. This species 

 of Armillaria is easily distinguished by its small size, scaly cap 

 and stem and very small spores. It differs from the European plant 

 in growing on wood.
