BOTANICAL EXCURSION TO NORTH CAROLINA. 48 
“Flora,” is referred to Boykinia occidentalis, in the supple- 
ment to that work, no pentandrous Saxifrage remains, except 
the ambiguous S. Sullivantii, Torr. & Gr. But the authors 
of the Flora having received fruiting specimens of this 
interesting plant, do not hesitate to remove it from the genus 
to which it was provisionally appended, and to dedicate it to 
their esteemed correspondent, the promising botanist who dis- 
covered it.} 
While descending the mountain on the opposite side, we 
met with Clethra acuminata, a very distinct and almost arbo- 
rescent species, which is well characterized by Michaux. The 
flowers were not yet expanded ; but towards the end of July 
we obtained from other localities specimens in full flower, 
while the racemes and capsules of the preceding year were 
still persistent. The conspicuous bracts, it may be remarked, 
are as caducous in the wild as they are said to be in the 
cultivated plant; usually falling before the flower-buds have 
attained their full size. We also saw Campanula divaricata, 
Michx., not yet in flower; and obtained fruiting specimens 
of the Convallaria umbellulata, Michx. (Clintonia, Raf., not 
of Dougl.). While the character in Michaux is drawn from

i. 575. — Genus a Saxifraga precipue diversum staminibus petalis iso- 
meris, et seminibus scobiformibus : a Boykinia calyce fere libero, atque 
seminibus ; ab Heuchera capsula biloculari, ete. ; a Leptarrhena stamini-
