This interesting plant was first collected by Dr. Asa Gray on 
Grandfather Mt., North Carolina, growing with S. Careyana, both 
plants being published under that name in Am. Journ. Sci., xlii. 
in 1842. Dr. Gray wrote that the difference between the two 
plants was not detected till they bloomed in Cambridge the 
following spring, when they displayed characters that remained 
constant in cultivation. 
On Walker Mt. .S. Caroliniana was growing in great abund- 
ance on wet rocks on the north side of the Gap for a space of 
possibly quarter of a mile along the road. It was 20-40 cm. or 
more high, the stems glandular pubescent, the leaves all in a 
rosette at the base, ovate-oblong or round-reniform, 2154-11 cm. or 
more long, 114-8. cm. wide, crenately dentate with broad, acute, 
mucronulate or obtuse teeth, glandular pubescent on the margins, 
acute, cuneate or deltoid at the base, gradually or abruptly con- 
tracted into a margined petiole, mostly about the length of the 
blade. Panicle diffuse, with a few very narrow, inconspicuous 
bracts, the white, two-spotted petals longer than the reflexed sepals. 
Filaments slender, clavate. Follicles ovate, acute, spreading, when 
mature probably over 6 mm. long. 
Engler, in his Monographie der Gattung Saxifraga, p. 137 
(1872), accords this species only varietal rank. .S. Careyana is 
glabrous, with only faintly spotted petals, spreading sepals and 
filiform filaments.
