Abies Fraseri, Lindl. The Southern fir had not as yet been col- 
lected north of the southern boundary of Virginia. To find 
the species within limits of the Northern States was one of our 
objects. After failing to secure it on any of the higher moun- 
tains explored, Mt. Rogers, the highest peak in Virginia, was 
resorted to. It was found to grow extensively on the upper 
parts of the mountain, extending from an elevation of about 
5,000 feet to the summit, 5,719 feet above the level of the sea. 
The growth was very fine and many large trees were observed. 
The mountain being wooded to the top, the soil and rocks are 
the damp most of the time, and the forest is less exposed to 
violent storms and winds than the more open peaks of North 
Carolina 
Tsuga Canadensis (L.) Carr. Iron Mts. about Comer Creek, alt. 
3,000 ft. Along Peak Creek, on Peak Mt,, alt. 2,200 ft. 
Tsuga Caroliniana, Engelm. In a deep gorge in Little Brushy 
Mt., near Broad Ford, alt. 2,100 ft. Slopes of Farmer Mt., on

The discovery of this very interesting hemlock at the two 
stations recorded brings it well into the limits of the Northern 
flora. Heretofore its northern limit was Blowing Rock Mountain, 
North Carolina.*
