nize, but in shade and along hedgerows, where conditions are more 
favorable it develops normally. These fields have not been ploughed 
and re-seeded in many years, and the Carex appears to be a permanent 
feature of the vegetation. I can certify that its relative proportions 
have not varied in five or six years. 
Agrostis canina L. It is surprising how many experienced col- 
lectors have failed to find this Agrostis, and it is probably a rare 
species in New England. There is a fine station for it in Franklin, 
in a low lying sphagnous meadow. 
Juncus effusus L. var. conglomeratus Engelm. This variety, which 
has been reported from only two or three stations in the United States, 
occurs in the same meadow. This is the station cited by Professors 
Fernald & Wiegand in their recent article on “The North American 
varieties of Juncus effusus," Ruopora 12: 86. 
Juncus effusus L. var. compactus Lejeune € Courtois. This is 
another product of the same attractive meadow. Mr. C. H. Bissell 
collected it here July 21, 1910. 
Festuca rubra L. var. subvillosa Mert. & Koch. I have found this 
variety in dry, rather barren, hillside pastures, where it is associated 
with the species, and is not rare. Although it so closely resembles 
the species, it is not difficult to distinguish between the two in the 
field. It has not been reported from elsewhere in Connecticut. - 
My first collection was made in 1904. 
Artemisia annua L. has become a troublesome weed about one 
house, where it persists as an escape from an old garden.

CYNANCHUM NIGRUM IN BARNSTABLE, MASSACHUSETTS.— While 
I was taking a walk from Hyannis to Barnstable, July 14, 1910, I 
came across two large patches of a curious twining plant, with the 
pods of a milk-weed, and small, dark purple flowers. These stations, 
one on each side of the railroad track, were about a mile east from 
Barnstable court-house, beside an old and little-used highway. Ex- 
amination showed the specimens to be Cynanchum nigrum (L.) 
Pers., an introduced plant from Europe, probably prized in the olden 
_ time for some not very obvious merit, officinal or ornamental.—
