small buds, due perhaps mostly to general shaamg of the trees from 

 which these specimens were taken. In others, of which No. 446 (p. 414) 

 is an example, the twigs are particularly heavy and large. This speci- 

 men also shows a decidedly vigorous type of acorn with a long stalk 

 and a broad cup. 



Some of the differences are so conspicuous and constant for a num- 

 ber of individuals that there appears to be several races or varieties in 

 this species. 



Scarcely more than a third of the- counties (33) have reported this 

 well-known tree. It would be interesting for others while reporting this 

 species to note if these racial characteristics, if such, are found. 



Quercus fnacrocarpa Michx. Mossy-cup, Blue or Bur Oak, Mossy-cup 

 White Oak, Scrub Oak. (Hist. Chen. Am. 2 pi. 23, 1801. Q. olivae- 

 formis Michx. f. 1812.) 

 The Bur Oak is more widely spread than perhaps any other oak in 

 the United States. It has been reported from 30 counties in Indiana. 

 In White County it occurs chiefly along the Tippecanoe and the lower 

 stretches of the creeks emptying into that river. Not many trees were 

 noted west of the Monon Railroad. A single tree of fair size, about 

 three miles directly north of Reynolds, enjoys an isolation by a radius 

 of several miles. A number of this species are to be found about two 

 miles south of Reynolds. I very much doubt its occurrence in Princeton 

 Township and likewise for Westpoint. It does, however, occur west of 

 these places, for I have seen it in abundance along Carpenter Creek in 

 Jasper County, near Remington. It is usually found in moist, rich soil, 

 near or some small distance from streams. Specimens were taken from 

 trees near the Ward School, three and three-fourths miles southeast of 

 Reynolds. The Bur Oak leaves an impression of a rather coarse appear- 

 ing tree throughout, easily distinguished from all other oaks. 



Quercus bicolor Willd. Swamp White Oak. (Neue Schrift Geo. Nat. 



Fr. Berlin 3:396. 1801), (Quercus Prinus platanoides Lam. 1873. 



Q. platanoides Sudw. 1893). 



The range of the Swamp White Oak in the United States is much 



more restricted than that of the two other white oaks here reported. 



In Indiana it is reported from 25 counties (scattering). It is very 



much less frequent in White County than other oaks. Several trees of
