Betula lutea, Michx. f. Slopes and summit of White Top Mt. alt,

There is a remarkably fine growth of this birch on the damp 
slopes of White Top. The younger trees all seem to have a 
silvery-gray bark, which on the older ones turns to the character- 
istic yellow. At an elevation of about 5,000 ft. on the eastern 
slope of the mountain a splendid tree was observed and the trunk 
measured. For the distance of about twelve feet from the ground 
the trunk is quite cylindrical and unbranched. Three feet from 
the base it measured twenty-two feet and ten inches in circum- 
ference. 
Alnus serrulata, Willd. Rocky banks of Peak Creek, on Peak 
t., alt. 2,200 ft. Near Marion, alt. 2,100 ft. Sandy shores 
of the South Fork Holston River east of Add Wolf, alt. 2,300 ft. 
The specimens collected at the latter locality are referred to 
the above species with some hesitation. The leaves are more 
sharply and prominently toothed, and have more pubescence on 
the under surface than is generally found in A. serrulata. There 
is a specimen of the same form preserved in the Columbia College 
herbarium, collected in Kentucky by Short.
