more feet in length. These runners arise not only from the 
base of the stem, but from the axils of the upper leaves, and 
very frequently from the apex of the weak ascending raceme 
itself, which is thus prolonged into a leafy stolon, hanging 
down into the water or mud, where. it takes root. Its habit 
and appearance are so unlike even the summer state of our 
northern C. rhomboidea, that we could not hesitate to con- 
sider it a distinct species. The subjoined diagnostic character 
will doubtless suffice for its discrimination.’ 
On the 7th of July we started for the high mountains 
farther south, haying hired a cumbrous and unsightly, but 
convenient tilted wagon, with a pair of horses and a driver 
(who rode one of the horses, according to the usual custom of 
this region), for the conveyance of our luggage, and which 
afforded us, at intervals, the luxury of reposing on straw at 
the bottom, while we were dragged along at the rate of two or 
three miles an hour. 
Our first day’s journey of about twenty-four miles was 
somewhat tedious, as we found no new plants of any interest. 
We saw, however, a variety of Lonicera parviflora? with 
larger leaves and flowers than ordinary, the latter dull pur- 
plish; probably the Caprifolium bracteosum, var. floribus 
violaceo-purpureis of Michaux. The following morning we 
reached the Watauga River (a tributary of the Holston) ; 
and leaving our driver to follow up the banks of the stream 
to the termination of the road at the foot of the Grandfather, 
we ascended an adjacent mountain, called Hanging-rock, and 
reached our quarters for the night by a different route. The 
fine and close view of the rugged Grandfather amply rewarded
