54 FOREST TREES. 
Aesculus flava—Sweet Buckeye. 
Stamens included in the yellow corolla; petals, 
four; calyx, oblong, campanulate; leaflets five, some-. 
times seven; smooth or minutely downy beneath;

The Sweet Buckeye is a stately tree, growing only 
in the richest soils, and reaching the height of sixty 
or seventy feet, with a diameter of three or four feet. 
It belongs to the subgenus Pavia, the husk of the 
fruit being smooth instead of prickly, like that of 
Horse Chestnut. Its bark and wood are nearly 
destitute of the disagreeable odor of the preceding 
species—hence the name of Sweet Buckeye. Its 
flowers and foliage are handsome, but itis usually 
bare of leaves by the first of September, which renders 
it unfit for ornamental purposes. The only use I 
have ever known to be made of its timber was for the 
construction of log cabins and the manufacture of 
wooden bowls. Itis common from Northern Illinois 
southward. It may be propagated like the Horse 
Chestnut. 
Aesculus Pavia—The Red Butkeye, 
Common in rich bottom lands in the Southern 
States, is the handsomest species. It has large, 
showy spikes of bright red flowers, but is little more 
than a shrub. It is said to be hardy at the North.
