23 Botanical Excursion to the Mountains of Notik Carolina. 



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 arborescent 

 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. Tlie 

 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 ob- 

 tained fruiting specimens of the Convallaria umbellulata, Michx., 

 (Clintonia, Baf., not of Dougl.) While the diaracter in Mi- 

 chaux is drawn from this species, the ' plan ta Canadensis' there 

 mentioned is the nearly allied Dracaena horealis of the Hortus 

 Kewensis. The two species are mixed in Michaux's herbarium ; 

 and, although the latter is almost exclusively a northern plant, 

 we found the two species growing together on the Grandfather^ 

 Roan^ and other high mountains of North Carolina. Towards 

 the base of the mountain we saw for the first time the Pyrula- 

 ria of Michaux ( Oil-nut, Buffalo-tree, &fc. Hamiltonia oleifera, 

 Muhl.)] alow shrub which is not of unfrequent occurrence in 

 rich shady soil. Its geographical range extends from the Chero- 

 kee country on the confines of Georgia, (where the elder Mi-
