TO NORTH CAROLINA, 221 
cimens of Heuchera villosa, (Michaux,) in fine flower, on the 
28th of June; although, in the higher mountains of North 
Carolina, where it also abounds, the blossoms did not appear 
until near the end of July. "This species is excellently des- 
cribed by Michaux, to whose account it is only necessary to 
add, that the petals are very narrow, appearing like sterile 
filaments. Although a smaller plant than H. Americana, the 
leaves are larger, and vary considerably in the depth of the 
lobes. It is both the H. villosa and H. caulescens of Pursh, 
who probably derived the latter name from the strong 
elongated rhizoma, often projecting and appearing like a suf- 
frutescent stem, by which the plant is attached to the rocks ; 
. Since he does not describe the scape as leafy, nor is this at 
all the case in the original specimens. The H. caulescens a. 
of Torrey and Gray's Flora,* with the synonym, must also 
be united with H. villosa, which in that work is chiefly des- 
cribed from specimens collected by Dr. Short in Kentucky, 
where everything seems to grow with extraordinary luxuri- 
ance. With these, the plant we collected entirely accords; 
except that the leaves are mostly smaller, and more deeply 
lobed; but this character is not constant. Soon after 
* The specimen from Mr. Curtis, the only one from the mountains of 
North Carolina which the authors had before them, and which they, reel 
rectly enough, considered as the H. caulescens of Pursh, is in too ad- 
vanced a state, and had lost from age most of the shaggy rusty hairs 
Which so copiously clothe the petioles and lower part of the scape, an 
the leaves being smaller and more sharply lobed, it was not recognized as 
the same species with the luxuriant Kentucky plant; but was partly con- 
founded with a different and larger-flowered species, the H cau (B 
(Torr. and Gray, l. c.) from Bancombe county. The latter (H. Curtisii, 
Torr. and Gray, ined.) has flowers quite as large as those of H. Americana, 
Spathulate lanceolate petals (apparently purple) which scarcely exceed the 
Obes of the calyx, and the filaments, which are less exserted than the 
styles, are pubescent under a lens. The aid of its discoverer, however, 18 
needed to complete the character of this species, the radical leaves being 
"perfect in our solitary specimen, and the cauline pair which it presents 
may very probably not be of usual occurrence. : 
Much to our disappointment, we did not meet with Heuchera hispida, 
_ although I have since learned, from an inspection of Barton’s herbarium,
