42 Botanical Excursion to the Mountains of North Carolina. 



corymbosum, with larger flowers than usual, a more upright 

 and larger-leaved variety of Hedyotis serpyllifolia, Oenothera 

 glauca (?., Senecio BalsamitcB, Rudheckia triloba, and a dwarf 

 variety of R. laciniata, Liatris spicata, Cacalia atriplicifolia, 

 Cynthia Virginica, Aster acuminatus, Solidago bicolor, S. spi- 

 thamcBa, Curtis in Torr. &c Gr. fi. ined., a very distinct dwarf 

 species, /S*. Curtisii, Torr. 6f Gr. I. c. not yet in flower, and /S*. 

 glomerata in the same state as at Grandfather Mountain ; also 

 Saxifraga leucanthemifolia, Sedum telephioides, Heuchera vil- 

 losa, Polypodium vulgare, the dwarf var. of Hedyotis purpurea 

 previously noticed, Sdrpus ccespitosus, and Agrostis rupestris ! 

 which are confined to the rocky precipice already mentioned. 

 The only tree is Abies Fraseri, a few dwarf specimens'of which 

 extend into the open ground of the summit ; and the following 

 are all the shrubs which we observed, viz. Diervilla trifida, 

 Menziesia globula.ris, Vacci?iium erythrocarpum, Rhododendron 

 Catawbiense, forming very dense clumps, Leiophyllum serpylli- 

 foliumj, Sorbus Americana, two to four feet high, Cratcegus 

 punctata only a foot in height, Pyrus arbutifolia var. melano- 

 carpa, Ribes rotundifolium ; and a low and much-branched spe- 

 cies of Alder, which Mr. Curtis proposes to call Alnus Mitchelli- 

 ana, in honor of Professor Mitchell ; but we fear it may prove to 

 be a variety of what we deem the A. crispa, Ait. from the moun- 

 tains of New^York, New Hampshire, &c., and Newfoundland, 

 although it has more rounded leaves, with the lower surface 

 nearly glabrous, except the primary veins ; while in the former 

 (to which the names of A. crispa and A. undulata are not very 

 appropriate,) the leaves are often, but not always, somewhat vel- 

 vety-pubescent beneath. To our list must be added an appa- 

 rently undescribed species of Vaccinium, first noticed by Mr. 

 Constable.* We made a hasty visit to the other principal sum-
