From the very great difference in appearance of the extreme — 
forms of this plant, I had about come to the conclusion that P. 
simplex, the large, ascending or erect condition, was actually 
specifically distinct from the smaller one with prostrate branches. 
But a study of the plant during the past spring in the vicinity of 
New York has convinced me that s¢mp/ex cannot be separated 
even as a variety, for I found them growing from the same clump. 
In shaded woodlands the simplex condition prevails, while the 
other prefers open places, and reaches its extreme degree of de- 
pression (var. pumilio, T. and G.) in very dry, sterile soil. There 
is, therefore, no more reason for maintaining varieties in it than 
in the case of Erigeron Canadense, which varies from an inch in 
height to ten feet or more. The type of P. Canadense, L is pre- 
served in the Linnzan Herbarium, and that of P. semplex, Michx. 
in the herbarium of Michaux at Paris, and so far as they go, are 
correctly understood. 
RUBUS MILLSPAUGHI, n. sp. 
Ascending, wand-like, entirely unarmed or with a very few, 
weak prickles above, glabrous throughout or the younger shoots 
scurfy-pubescent. Stems 144-4 meters long; leaves long-peti- 
oled, pedately five-foliolate or some of those on the twigs three- 
foliolate; leaflets thin, oval, glabrous on both sides, long-acumi- 
nate at the apex, mostly rounded at the base, 12-15 cm. long, 
about 5 cm. wide, sharply but not deeply serrate; stalk of the 
terminal leaflet 7-10 cm. long; inflorescence loosely racemose ; 
bracts linear-lanceolate; pedicels slender, ascending; sepals 
lanceolate, acuminate; fruit black, about 10 mm. long. 
In rich woods, Point Mt., West Virginia, at 3,500 ft. altitude 
(C. F. Millspaugh). Nearest to &. vz//osus, but evidently a dis- 
tinct species. Curiously enough there is a leaf of this plant glued 
down on the sheet of R. Canadensis, L. in Herb. Linn., and it 
appears to have been included in his description of that species— 
the specimens furnished by Kalm.

A. Eupatoria, var. parviflora, Hook. i. 196 (1832). 
The American plant has certainly been erroneously referred 
to the European A. Eupatoria, which is very distinct from it, by 
its larger flowers and fruit, denser inflorescence, much greater
