1912] Flora of the Boston District,— XV 111 
specimen collected by the late Edward S. Hoar is in his herbarium 
which has recently been presented to the New England Botanical 
Club by his daughter, Mrs. M. B. L. Bradford of Concord, Massachu- 
setts. Examination proves it to be C. vesicaria L. The herbarium 
of Rev. Thomas Morong is in the Herbarium of the New York Botanic 
Garden at Bronx Park, New York City, and, through the kindness 
of Dr. J. K. Small, the Ashland plant has been examined and identified 
as Carex hirta L. It was collected in low, grassy ground, on June 30, 
1877. I have in my herbarium specimens of C. hirta L. collected by 
Dr. Morong in Ashland, June, 1877, and labelled C. trichocarpa Muhl. 
"This is probably of the same collecting as the specimen just referred 
to. Prof. L. H. Bailey wrote me in 1884 in regard to this plant, 
“An interesting find. It is C. hirta L..... I have not the species 
from this country, so I took a piece." I also have two specimens of 
C. hirta L. collected by Dr. Morong in Ashland, July 6, 1885. These 
Ashland plants have been recorded in Rhodora xiii. 250, 1911, under 
C. hirta L. 
Prof. Bailey published a note on C. hirta L. in the Botanical Gazette 
for June, 1885, on page 295. He mentions its general resemblance 
to C. trichocarpa and says, "Introduced from Europe. Ashland, 
Mass., 1877, Thos. Morong; in ballast, Philadelphia, 1880, F. L. 
Scribner; and about Boston, Wm. Boott. Mr. Morong writes me as 
follows in regard to this species: 'I have collected it for several years 
in succession. I first found it by the roadside in rather low lands 
and afterwards in yards around dwellings, among grass. I presume 
from these situations that it must have been introduced into this 
locality. " Carex trichocarpa Muhl. has been found in New England 
only in the western portions, while C. hirta L. has occurred at sev- 
eral stations in eastern Massachusetts (see RHopora xii. 188, 1910).
