of Maryland and Pennsylvania, where they are traversed by the 
Cumberland road. From the Potomac at some distance above 
Cumberland, the great Back Bone of the Alleghanies was cross- 
ed in Maryland, where it presents a pretty formidable elevation, 
and several plants were observed which were thought to be con- 
fined to a more southern range, such as Menziesia globularis and 
Galiwm latifolium. 'The open glades on the other side present- 
ed many features of Kentucky vegetation. Virginia was enter- 
ed near Mount Carmel Town, and a rude, wild region: was trav- 
ersed to 'T'ygart’s Valley River, in Randolph County. The high 
Cheat Mountain was then crossed nearly where it merges in the 
Green Brier range, and Angelica Curtisii, Bucxt., as well as Aco- 
nitum reclinatum, Gray, were first met with. In the journey 
through Pocahontas County to Huntersville, fruiting specimens of 
the little known Rhamnus parvifolius, Torr. and Gr. Fl., were 
collected, a species which proves to be a perfectly distinct one, 
and has also been found by Mr. Bucxuey in Alabama. In the 
route eastward across the mountains from Huntersville to the 
Warm Springs, the rare Helianthus levigatus, Torr. and Gr., 
and Andromeda floribunda, Pursu., (which is A. montana of 
Bucxuey, ) were abundantly found. A mountain meadow on Nap’s 
Creek, east of Huntersville, also furnished a stout Géntian with 
crowded ochroleucous flowers, and with much the habit of G. 
Andrewsii. It was naturally enough confounded with G‘: ochro- 
leuca, and specimens have been distributed under this name. It 
is however quite a different species from the real G'‘. 0

Our Gentians will soon be cleared up, we trust. Meanwhile a

Springs the expedition pursued its course, by way of the Hot 
Springs and the White Sulphur Springs, along the base of Peter’s 
Mountains to the Kanhawa River, which was crossed at Toney’s
