GENERAL NOTES. : 
New Silphium from Tennessee—Srmpnium BRACHIATUM. 2. sp— 
Stem 3 to 5 feet high, square, smooth and glaucous: leaves all opposite; lower 
short petioled, gradually attenuate from a dilated, truncate or subhastate base, 
slightly decurrent on the short ciliate petiole, roughened on the upper side, : 
smooth on the lower, except the principal veins, which are slightly hirsute, It en 
regularly and repandly dentate, 4 to 6 inches long, thin and glaucous green; UP- 
permost sessile, ovate-lanceolate, ciliate on the margin: heads solitary on slen- 
der peduncles: involucre of about 15 or 16 foliaceous subsquarrose ovate scales = 
rays about eight, } inch long: receptacle 1 inch high: akenes nearly orbicular, | 
narrowly winged and slightly notched at the apex. ue 
Collected July 14th, 1867, on the western slope of the Cumberland Moun- : 
tains, one mile from the railroad tunnel at Cowan, Tennessee. . 
The species is very distinct and apparently plentiful in the locality, bat 
has never been observed by me in any other part of the State. The only specl- a 
mens now in collections are in the herbaria of Prof. J. W. Chickering and Pe : 
Lester F. Ward, of Washington, and Mr. Wm. M. Canby, at Wilmington, t : 
which gentlemen I gave specimens at the meeting of the A. A. A. S. at Nash- | 
ville in 1877, under the spurious name‘S. perfoliatum, var. One specimen J have : 
recently sent to Dr, Gray, not finding it described in his recent volume 0D er i 
omposite, and he expressed his regret that I had not sooner called hig 
attention to the existence of this species.—A. Gattincer, M. D., Nashville,

Cynoglossum grande, Dougl.—This species has a long-peduneled a ts 
florescence, terminating a leafy stem. The bracts of the panicle are S™” 
ingly all wanting; but they are really present in the shape of large leave 
By the coalescence of the branches to the stem and to each other, the false Ta : 
cemes are carried far away from the leaves to which they belong. That pants 
the case is seen best early in spring, when the leaves and flower-buds are closel¥ 
together. At that time the lower leaves have buds or undeveloped br: anches ; 
_ their axils, while four to six of the upper ones are perfectly empty. ae 
above each empty axil, and not far away from it, there is a cluster of flower” 
buds; the lowest above the first empty leaf, the next cluster above the second — i 
of these leaves, and so on to the last leaf or bract. The first of the false™® 
cemes is often few-flowered or rudimentary, and then it remains low down oF 
the peduncle, or among the leaves, sometimes nearly in the axil of its leaf sag 
or occasionally more, of the upper racemes are without bracts. —W- N. Suse
