A small tree, but rarely exceeding 30 — 35 feet in height: The stem and 
very fragile branches covered with a white bark. The leaves alternate, 
and crowded near the summit of the branches, exceed in magnitude those 
of any other of our plants, they have been found 35 inches long, and 9 — - 
10 inches wide. They are acute at the summit; tapering and cordate, 
but scarcely auriculate at base, glaucous underneath, and when young 
clothed with a silvery silken pubescence. Petals 4 — 5 inches long, ovate, 
white, tinged with purple at the base, fragrant. Cone oval. 
To complete the view of this interesting genus, I have inserted this spe- 
cies although it has never yet been found within the limits strictly assign- 
ed to this work, yet, in Lincoln county, North-Carolina, it approaches so 
near the frontiers of this State, that it would be a matter of some surprise 
if it should not yet be discovered along the southern declivities of the Sa- 
luda Mountains. 
Grows 10 or 12 miles to the South-east of Lincoln Court-house, North- 
Carolina, and in Tennessee. 
Flowers May to Juty.
