for plants which ordinarily are supposed to be rare in Eastern Massa- 
chusetts, or have not heretofore been known in that region. 
CYPERUS ARISTATUS Roth. ‘This plant was found about the 
middle of August in great abundance below high water mark on the 
sandy strand surrounding Heard’s Pond, Wayland. Later it was 
found in considerable abundance in a similar location at the southern 
end of Lake Cochituate. ‘he plant is very local in Eastern Massa- 
chusetts. It has been found at Mystic Pond by Manning and Perkins, 
and at Brookfield by Harper (see herbarium of New England Botani- 
cal Club). Mr. F. F. Forbes informs me that he found it in 1904 
and 1905 at Lake Cochituate. 
HEMICARPHA MICRANTHA (Vahl.) Pax. This was found also in 
great abundance mixed with the last named plant on the strand of 
Heard's Pond. It was also found on the strand along the western 
shore of Farm Pond, Sherborn. ‘This likewise seems to be a very 
local plant in Eastern Massachusetts, except possibly in the Cape Cod 
region where it is more abundant. ‘There are specimens in the 
herbarium of the New England Botanical Club from Andover (Blake), 
and Brookfield (Harper). It has also been found by several botanists 
at Winter Pond, Winchester; and Mr. Forbes has collected it on a 
gravelly bank of the Charles River at Cow Bay, West Roxbury. 
POTENTILLA PALUSTRIS (L.) Scop., var. viLLosA (Pers.) Lehm. 
The plants of this species growing about the mill pond in the Charles 
River at South Natick have leaves densely silky beneath and from 
slightly to very conspicuously silky above, and glandular inflorescence. 
They should therefore be referred to this variety. Heretofore this 
variety apparently has not been known from south of Washington 
County, Maine, and the St. Lawrence System. 
VioLA AFFINIS LeConte. A strange violet was found in consider- 
able abundance in a rather low wild woodland on the east bank of the 
Charles River about one mile below Wellesley. It proved to be very 
typical V. affinis which, so far as the writer can learn, has not previously 
been reported from east of the Connecticut River. 
ARALIA NUDICAULIS L., var. ELONGATA Nash. A patch of very 
peculiar looking wild sarsaparilla occurs in a woodland region just 
south of the Charles River at a point directly south of Needham 
Village. The narrowly lanceolate, long-acuminate leaflets agree well 
with Mr. Nash’s description of this variety which he reported only 
from the Catskill Mts., New York.
