AMERICAN OAKS 35 



Q. macrocarpa, to which it comes near; acorns oblong, larger than Q. 

 olivaeformis and smaller than Q. macrocarfa, entirely enveloped in the 

 cup, which is scaly, having a very fine filamentous fringe. The wood 

 resembles Q. alba. More abundant on the east banks of Lake St. Clair 

 than any other species of the genus.

Usually 30 or 50 feet high and 2 or 3 feet in diameter, spreading and 

 throwing out branches to the bottom of the trunk. Plentiful near Phila- 

 delphia ; Burlington, New Jersey ; and on the east banks of the Hudson, 

 ten miles from New York. The wood is said to be exceedingly hard, 

 and is extensively used in the navy yards and for other purposes. 



Pursh says 50 or 60 feet high. It grows, according to Pursh, from 

 Canada to Florida in most forests.

 omnino tegente.

I had my specimen from the garden of the late Mr. Wm. Bartram, near 

 Philadelphia. 



Of all the oaks that grow in moist situations this is by Michaux con- 

 sidered the best, and it is held in considerable esteem for the uses to which 

 its wood may be applied. It has the further advantage of attaining to 

 very large dimensions, a height of about 80 feet, with a stem of 8, 10, or 

 even 12 feet in circumference. Pursh indeed observes that its height is 

 only from 8 to 15 feet. 



Called also, according to Pursh, Swamp-post Oak and Water-white 

 Oak. The acorns being entirely concealed by the cups, gives its other 

 name. 



It grows, according to Pursh, in swamps from Carolina to Florida and 

 on the Mississippi.
