I came upon great quantities of this species growing on the dry 
sand and quartzite hills north of the deep cafion of the Tal- 
lulah River, in Rabun county, at an altitude varying from 1,600 
to 1,800 feet. Somewhat later, on a trip to the source of the Tal- 
lulah River, it was collected on the lower sandy slopes of the 
Thomas Bald, a high mountain on the North Carolina and Georgia 
boundary. There it ranged from 2,500 to 3,000 feet, and was 
scattered through the forests, at some places in great abundance, 
and grew vigorously, apparently none the worse for its separation 
from the influences of the coast. 
The first record of the occurrence Gaylussacia dumosa at an 
appreciable distance from the seacoast seems to be in Prof. 
Porter's Catalogue of the Plants of Lancaster County, Pa. (Mom- 
bert’s History of Lancaster County, Pa., p. 590). Prof. Porter 
found it in that section in.a swamp, remarkable for its peculiar © 
plant life, near Smithville. Mr. J. J. Carter encountered it some- 
what later in a swamp bordering on the Serpentine Barrens, in 
the southern part of the same county. 
The most interesting and striking fact suggested here is this: 
At the Pennsylvania localities the plant grows in swamps, and at 
Smithville is actually in the water, whilst in the mountains of 
North Carolina and Georgia, as far as I have observed, it selects 
the driest situations afforded.

Grows onthe walls of the cafion at Tallulah Falls, Georgia 
Collected in flower in April, 1893. Altitude 1,600 feet. This 
most likely locates the southern limit of the geographical range of 
R. Millspaughii. Being a typically high mountain species, it is not 
to be expected much below 1,600 feet, and just south of the above 
mentioned locality the Blue Ridge “runs out’ into the plains. 
Further south the land decreases gradually in altitude until the 
gulf is reached. According to my observations the above plant 
thrives most vigorously at altitudes ranging from 4,500 to 6,000 Me “ 
feet. It grows well at lower elevations, but never in such a pro: 2 
lific manner.
