Sargent^ in his Sylva of North America gives Leana a place 

 with imhricaria; and in his Trees of North America, he says^ that 

 Q. Leana is beheved to be a hybrid between Q. imhricaria and Q. 

 velutina. Britton in his "Flora of United States and Caiiada,"^ 

 says that Q. Leana is a hybrid between Q. imhricaria and Q. velu- 

 tina, while the new Gray manual makes no mention of it what- 

 ever. 



Historically then we see that Nuttall is the only one to consider 

 Leana a distinct species, and that the other men have considered 

 it a natural hybrid between imhricaria and either velutina or 

 coccinea. Mr. Ward favored coccinea, but the later men, Sar- 

 gent and Britton, have returned to Lea's first suggestion and 

 have considered velutina the other parent. Lea mentions Q. 

 ruhra but disproves the possibility of it having entered into the 

 combination, their fruits differing widely. Mr. Nuttall men- 

 tions Q. amhigua, the gray oak, and his statement that the fruit 

 ''appears to be wholly that of the gray oak" can be neglected 

 because the gray oak is no longer recognized as a species. Mr. 

 Ward mentions Q. Phellos and gives the reason for not consider- 

 ing it that it was not found in the locality of his hybrids. It is 

 not found in the vicinity of Cedar Point and need not be con- 

 sidered here. 



Description of Cedar Point Representatives 



On Cedar Point there are several trees that have been con- 

 sidered by the late Professor Kellerman, Professor Jennings and 

 others to be representatives of Lea's oak. Cedar Point is an 

 almost isolated piece of land and while oaks are very abundant 

 there, they are confined to practically three species: imhricaria, 

 velutina, and ruhra. These with one or two representatives 

 of macrocarpa and the half dozen or so representatives of Lea's 

 oak mentioned above complete the list. Professor Moseley^° 

 mentions one oak of a hybrid nature which he suggests may be a 

 cross between imhricaria and Marilandica. In 1910 a tree was
