ADDITIONS TO THE AEBOKESCENT FLOKA OF 

 NORTH CAROLINA 



By W.W.Ashe 



It was not intended by the authors* of the "Trees of North Caro- 

 lina" to include all the trees in the State, since it is stated in the in- 

 troduction that a number of others might be added. It might be well, 

 however, to add to this already very full enumeration such others as 

 are knoAvn to occur that the list may be as complete as possible. The 

 addenda, omitting any hawthorns or semi-shrubs and allowing for the 

 elimination of two from the original list by treating them as varieties, 

 increases the number of species to 180 in place of 166, If to these 

 are added the large number of smaller trees and semi-shrubs, includ- 

 ing the arborescent hawthorns, the number nearly reaches 240, and 

 with the inclusion of some of the best marked varieties exceeds 260. 

 It is believed that even this total is incomplete, and that fuller investi- 

 gations will further augment it, for many portions of the State have 

 never yet been carefully explored. 



Salix discolor Muehl. A small tree which occurs along moun- 

 tain streams. 



Betula papyrifera cordifolia (Regel) Fern. The canoe birch 

 occurs in the Black Mountains but is not known to occur between this 

 station and Connecticut and northern New York. (See Rliodora, 

 Apl. 1918.) It is readily separated from the other birches on these 

 mountains by its pinkish or brownish bark, which is in thin papery 

 layers, as well as by its deeply cordate leaves, and declining, not 

 erect, fruit cone. 



Several forms of Hicoria (the generic name employed for Carya in 

 Trees of North Carolina) are not noted. 



Varieties of Hicoria pallida Ashe. This species varies much 

 in the form of fruit and nut. The type can be considered the fruit 

 form which is common around Chapel Hill and Raleigh, N. C, where 



nv. C. Coker and H. R. Totten, Chapel Hill, N. C. Published by the authors 1916.
