capable of conveying our luggage and a single person besides the 
driver, a simple shoemaker who had never before undertaken so 
formidable a journey, and who accordingly proved entirely want- 
ing in the skill and tact necessary for conducting so frail a vehi- 
cle over such difficult mountain tracks, for roads they can scarcely 
be called. We had first to ascend the steep ridge interposed be- 
tween the Middle and the South Forks of the Holston, called 
Brushy Mountain, during the ascent of which we commenced 
botanizing in earnest. The first interesting plant we met with 
was Sazifraga erosa of Pursh, but only with ripe fruit, andeven 
with the seeds for the most part fallen from the capsules. ~The 
same locality also furnished us with a few specimens of the pretty 
Thalictrum filipes, Torr. § Gr. (to which the name of T. 
im, DC. must be restored,) a plant which abounds along 
all the cold and clear brooks throughout the mountains of North 
Carolina; where it could not well have escaped the notice of Mi- 
chaux, in whose herbarium DeCandolle found the specimen (with 
no indication of its habitat) on which his J. clavatum was es- 
tablished. The authors of the Fora of North America, having 
only an imperfect fruiting specimen of their Z. filipes, and sict 
sufficiently remarking the discrepancies between the T. clava- 
tum, Hook. fl. Bor-Am. and the figure and gata of a 
Candolle’s plant, in regard to the length of the styles, ass the 
former to be the true T. clavatum, and described their own ee

the figure of DeLessert, (except in the greater, but variable length 
of the stipes to the fruit, and in the veining of the carpels, which, 
doubtless by an oversight of the artist, is omitted in the figure, ) 
as to leave no doubt of their identity. ‘The subarctic plant may 
be appropriately called 7’. Richardsonii, in honor of its discov-

character of our own plant.* The flowers of this species are
