PLATANACE/E. 



PLATAN US L. 



P. occldentalis L. Buttonwooo. Buttonhall. Sycamore. 

 Plane-tree. A common and well known tree in river bottoms. 

 Remarkable for shedding its bark in thin scales with its leaves, 

 leaving the surface beneath white or gray-green. Height and 

 diameter of trunk both considered, this is our largest tree. 



JUQLANDACE/C. 



JUGLANS L. 



J. cinerea L. Butternut. White Walnut. Very common, es- 

 pecially along streams. A medium-sized tree with rather smooth, 

 grayish bark. Wood brown, rather hard, much used in cabinet 

 work. The nuts are gathered in considerable quantities. 



J. nigra L. Black Walnut. Not common. Most plentiful in 

 the western part of our range. Not reported north and east of 

 Broome county. This seems near the northern limits of the 

 tree's range. A large tree with rough bark and a longer trunk 

 than the preceding. Wood hard, dark, and valued above that 

 of any other of our forest trees for cabinet work.
