Notes on certain Plants of our Eastern Flora. 
Rubus Montanus (RK. villosus montanus Porter, in BULLETIN 17: 
15). Recent observations on this Rudus in its native haunts has 
led me to believe it worthy of elevation to specific rank. Its 
slender stalks are less prickly than those of R. vil/osus and usually 
reddish, but the chief difference lies in the fruit, which is much 
smaller, of oblong shape, often narrowed toward the apex (thimble- 
like), scarcely fleshy and possessed of a peculiar spicy flavor. 
Common and abundant on the mountains of New York and 
Pennsylvania, where it is popularly known as the “mountain 
blackberry.” It no doubt extends further south. 
Solidago Canadensis L.—To this species must probably be 
referred specimens collected last summer by Mr. J. H. Redfield — 
near Long Pond, Mt. Desert Island, Maine. Sent me under the 
name of S. serotina, they are clearly separated from it by their 7 
low, slender, pubescent stems, narrower, more numerous, long- - 
acuminate, triple-nerved leaves, smaller panicles and smaller heads, — 
with acute involucral bracts and shorter rays. The very same 
form occurs also in Pennsylvania at several stations along the 
Susquehanna river, and shows a near approach to S. rupestris Raf, 
which Dr. Gray, in the Synoptical Flora, surmises may prove to 
be ‘an extreme form of S. Canadensis.” If this view be adopted, — 
Mr. Redfield’s plant must take the varietal name supesiris (Raf.). = 
ASTER CORDIFOLIUs L.—Most frequent and plentiful in 0% 
Middle States. It blooms profusely, adorning the woods and 
fields during the months of September and October. From ees 
allied species it is readily distinguished by its foliage. The radi- 
cal and lower cauline leaves are orbicular-cordate or oblomg- 
cordate, scabrous above and beneath, thin and membranaceous . 
tne shade, thicker and stiffer in open grounds, coarsely serrate, 
and with petioles not at all, or only slightly, margined. a 
- A. CORDIFOLIUS POLYCEPHALUS n. var:—-More robust and 
branched than the type; leaves smaller, the upper ones and ei 
bracts ovate and sessile; panicle ample; heads usually sm4@™* 
and very numerous; rays deep blue and the disk-florets dark pu‘P 
(as in A. /ateriflorus), or both of them sometimes pale or whitis®
