ARENARIA BREVIFOLIA Nutt.; T. & G. Fl. N.A. 1: 180. 1838. 
I have long suspected the occurrence of this, the rarest of our 
eastern American. Avenarias, in North Carolina. In 1890 Mr. 
Heller collected fragmentary and imperfect specimens of an 
Arenaria in Rowan County. Some years later I found similar 
specimens on Dunn’s Mountain, near Salisbury. During the 
spring of 1896 I had an opportunity to visit Dunn’s Mountain 
and found the species in full bloom just as it occurs on Stone 
Mountain, Georgia; the plants from the two mountains are al- 
most identical. 
RHEXIA Mariana L. Sp. Pl. 346. 1753. 
As far as I have observed, Rhexia Mariana prefers sandy places 
at no great distance from the Atlantic and Gulf coasts, although 
it does occur at many points in the middle districts of the 
Southern States, and is said to extend up the Mississippi Valley to 
Missouri. The first altitude worthy of note at which I found the 
species was at about 300 meters on Stone Mountain, Georgia. The 
following year, 1895, I collected a few specimens of a delicate 
form, apparently referable to this species, on the mountains near 
Ellijay, Gilmer County, Georgia, at an altitude of about 400 
meters. The leaves of this form are thin, oval, ovate or elliptic 
and short-petioled. Much to my surprise, on reaching the 
summit of Table Mountain, South Carolina, last summer, I found 
the typical state of the plant thriving at an altitude of almost 1600 
meters. 
SABBATIA CAMPANULATA (L.) Britton, Mem. Torr. Club, 5: 259. 1894. 
Dr. Gray has recorded * the mountains of Georgia as an ex- 
tension of the range of this normally coast plant. I do not know 
to how great an altitude the species ranges in Georgia, but I have 
collected it at an elevation of nearly 1000 meters on the summit 
of Table Mountain, South Carolina, and the only noticeable differ- 
ence between the mountain specimens and those from the low-
