CUPULIFERAE 131 



Two trees growing close together in a field on the farm of R. 

 W. Shackelford, northeast of Autaugaville (region GC), ohserved 

 in fruit in the fall of 1!)'3T. seem to represent hyhrids Ijetvveen this 

 and Q. falcaia and Q. Catcsbaci respectively. Some oak stumps 

 close by may represent one or more of the parent trees, but since 

 they were cut the best evidence for identifying the hybrids (if such 

 they are) is lost. 



Quercus heterophylla. Mx. f. (Bartram Oak.) 



Thi.s species, or hybrid, has been known for over 100 years, and re- 

 ported from various places scattered from New York to Texas. It is sup- 

 posed to be a hybrid between the willow oak and one of the red oaks, but 

 its exact parentage has never been settled. A single specimen was found 

 bv Mohr and Sudworth near Falkville, in the Tennessee \'allev, 35 or 40 

 vears ago. (See Mohr, Bull. Torrev Bot. Club 19:309. 1892; 'Plant Life 

 of Ala., 473. ) 



Quercus Nuttallii, l^almer (Jour. Arnold Arl^oretum, 8:52-54. 

 1927) 



A medium-sized tree with the smoothest and greenest bark of 

 any of our lobed-leaved oaks, thin deeply lobed leaves which are 

 green on both sides, and medium-sized acorns. There are a few 

 specimens of what appears to be this species planted for shade in 

 the streets of Tuscaloosa. 



At the time this was described it was known only from Mis- 

 sissippi, Arkansas, Louisiana, and perhaps Missouri. But I col- 

 lected it the same year ( li»27 ) in the bottoms of Bughall Creek in 

 Bullock County (region V), and in the Mobile delta in Baldwin 

 County opposite Mount \>rnon (region 14), where it seems to 

 be rather common : and I had ])reviously seen what may be the 

 same thing in alluvial situations in Tuscaloosa and Wilcox Coun- 

 ties. This may be what Dr. Mohr called Quercus Tcxana in the 

 Plant Life of Alal)ama. and it may prove to be pretty widely dis- 

 tributed in the state.
