Clayey soil. North Greenbush and Rensselaer. Flowers May 

 12-20, fruit ripens during September. This species is very distinct 

 and easily recognized by its peculiar oblong ovate leaves with acu- 

 minate apex and on fertile branches with cuneate base, making 

 them pointed at each end. On 3''oung and vigorous shoots they are 

 usually broadly rounded at the base, and are sometimes 3.5-4 

 inches long and 2-2.5 inches broad. They are generally more 

 elongated when growing in the borders of woods than when in 

 more open exposed places. The autumn buds are clothed with a 

 varnish which is sticky in warm weather. Though found in sev- 

 eral places on the east side of the Hudson river, no example of it 

 has yet been found on the west side of the river.
