Wardu occurs on the opposite shore hardly two hundred yards 
distant, the two species being respectively confined to the north 
and south sides of the river. The form of Sa/zx Wardi occurring . 
there is peculiar; the bushes are smaller than any heretofore ob- 
served, diffusely branched and the branches decumbent or almost 
prostrate, spreading radially and forming large, tangled mats, 
seldom rising more than six inches.above the ground.

I was much surprised to find quantities of this scrub oak on the 
summit of King’s and Crowder’s Mountains near the southern 
boundary of North Carolina in the summer of 1894. The locality 
is within several miles of South Carolina and about one hundred 
miles east of the Blue Ridge.

The existence of the red oak in Georgia was unknown to bot- 
anists before 1893. In that year I discovered a few trees just 
south of the North Carolina boundary, on the summit of the 
Thomas Bald, at an altitude of 5200 feet. The trees were stunted 
and irregular, as is characteristic at high altitudes. Last year, 
however, I found a remarkable development of the species in the 
northwestern ‘corner of Georgia, in Catoosa county. The species 
abounds in the limestone «bottoms ;” trees three feet or more in 
diameter are not uncommon, their trunks, naked often for seventy- 
five feet from the ground, are so straight that it is impossible to tell 
which way they will fall when cut off at the base. The thick bark 
is more or less mottled, whence the local name “ Leopard Oak.”

Although extending over most of the western part of Georgia, 
this species of hackberry reaches its greatest development in the 
rich limestone “ bottoms” in the region east of Lookout Moun- 
tain. Gigantic trunks, three or four feet in diameter, are very 
common, and are covered with innumerable corky warts, which 
range from one to two or even three inches in height.

I have lately discovered a new station for this rare plant. It
