29. Hicoria microcarpa (Nutt.) Britton. Small-fruit- 



ed Hickory. 



A tall and rather narrow tree that is sparingly 

 scattered in upland woods from Orange to Caldwell 

 Counties so far as now known; bark usually flaky, 

 sometimes hardly flaky in lower half of tree; nuts 

 flattened-ovate, thin-shelled, sweet, a large per cent 

 wormy with a hole in the side; hull thin, tardily 

 dehiscing. In the spring this species is easily dis-

 buds, which are just breaking when H. ovata is in 

 flower. Main terminal buds small and ridged by 3-5 

 thickened scales that fall off during the winter. Dates 

 of flowering: April 8, 1911; April 18, 1912; April 

 23, 1916. Examples: tree by street at end of Dr. 

 Lawson's tennis court; tree in southwest corner of 

 lawn at "The Rocks."

 thick-shelled nut with a hull that does not open at 

 all or only partially, and is usually furnished with a 

 neck at the base ; leaves broader and more noticeably 

 toothed than in H. microcarpa; buds like those of 

 H. microcarpa. In Chapel Hill we have a form of
