punctata, beech, yellow and black birches, buck-eye, and soon upon 
the rich soil of the mountain side come large trees of Prunus seroti- 
ma, with sugar maples, chestnut, both the lindens, white and red 
oaks, hickories, cucumber trees, tulip tree, and all the trees which 
compose the magnificent forest of the southern Alleghanies. 
All too soon, on the 21st, the pleasant companionship was broken 
up. Dr. and Mrs. Gray, having accepted the kind invitation of Mr. 
Arthur Cowles to visit some points in Ashe Co., which were explored 
by Dr. Gray in his first visit of 1841, left in company with hin, for 
a three days drive to his home at Deep Gap, and two or three more 
to the railroad at Marion, Virginia. Prof. Sargent and Mr. Canby, 
with Mr. Loring and family, descended the northern side of the 
mountain the same day to Wilder’s Forge, and thence over 
the Iron Mountain to Johnson City; and Mr. Redfield fol- 
lowed a day or two later. In the descent were noticed on 
the lower flanks of the mountain, Azalea calendulacea, Habenaria 
pscycodes and Asclepias phytolaccotdes. In crossing the Iron Mountain 
range were seen Diphylleta cymosa, Astilbe decandra, and Carda- 
mine rotundifolia. Aristolochia Sipho frequently displayed its 
pyramids of huge cordate leaves. Several species of Magnolia 
abounded in the gorges of the Iron Mountains, and _ there 
were sufficient indications that a thorough exploration of that range 
would yield a botanical harvest. Among the limestone rocks a few 
‘miles east of Johnson City (a locality noticed in 1876) was collected 
Asplenium parvilum, associated with Camplosorus rhizophyllus. 
At Jefferson, the county seat of Ashe County, Dr. Gray made a 
hurried ascent of Negro Mountain, which rises close to the village. 
True to his recollection of 1841, he went directly to the point where 
he then discovered Aconitum reclinatum, and found it, but not yet in 
flower. Roots were taken for cultivation in the Botanic Garden at 
Cambridge. ‘There he also collected Saxtfraga Caroliniana, but not 
S. Careyana, which alone was found further south. A fresh com- 
parison of the two very similar plants confirmed the published 
characters of the species. yee R:

ovularis, Torr., Var. cylindricus, Torr.) 
Culms 6 in. to 20 in, high, smooth, triangular; leaves linear, rough- 
ish on the margins especially near the apex; involucre of about 6 very 
unequal rays, rough on the edges; umbel about 7 rayed; rays 4 in. 
to 24 in. long ; heads cylindrical, or sometimes oblong, of numerous 
linear spikes, the lower of which are somewhat reflexed ; spikes usu- 
ally 2-flowered, the two lower scales empty ; scales ovate, obtusish ; 
achenium linear-obvate, or linear oblong, triangular, shorter than the 
scale; styles trifid; stamens three. Roots fibrous, from clustered 
tubers. Very distinct from C. ovularis, Torr., with which it has been 
confounded.
