interested in finding out what the plant might be, that I went to the 
place where it grew, and collected a number of specimens, one of which 
I have sent to the Gray Herbarium. I did not know the plant, but 
found out later that it was Menyanthes trifoliata L. ‘The past summer, 
while on a collecting trip to the Cranberry Glades, Pocahontas County, 
W. Va., Mr. A. B. Brooks, one of the party, brought me some speci- 
mens of the same plant which he had collected in one of the glades. In 
so far as I have been able to ascertain, these two localities are far 
south of the previously reported range for Menyanthes trifoliata. How- 
ever, the altitude and the glades correspond to the northern habitat 
to some extent.— Jonn L. SHELDON, West Virginia University,

ZANNICHELLIA PALUSTRIS, AN ADDITIONAL RECORD.— I have to 
record an interesting addition to our list of the Najadaceae, published 
in Ruopoma, xi. 205-208. 1909. Professor Wm. G. Farlow has 
presented me with a specimen of fruiting Zannichellia palustris L. 
which he collected in the northwestern corner of Brighton “‘in a brack- 
ish marsh” on the border of Charles River in August, 1877. Professor 
Farlow writes, under date of December 6, 1909, “I collected Zanni- 
chellia growing with Ruppia on the Charles River between Brighton 
and Newton. After leaving Faneuil the railroad now crosses a marsh 
by an embankment which passes opposite the old Stickney place in 
Watertown. In the ditches near the river towards the Faneuil end 
of the marsh was Zannichellia and farther back from the river was 
Zizania. Probably the plants have now disappeared." ‘The locality 
is nearly opposite the Watertown Arsenal. 
These details are of special interest in view of the rapid changes 
that are in progress in the region about Boston. The construction of 
the large dam near the mouth of the river has converted the area under 
consideration into a fresh water way, maintained at a constant level, 
and the plants that haunt salt or brackish situations, such as have 
always heretofore existed along the banks of the Charles River as far 
up as the dam in Watertown, are rapidly disappearing, if indeed they 
exist at all, 
Zannichellia palustris is an uncommon plant in New England, 
inhabiting sparingly the brackish marshes along the coast, and but 
rarely occurring inland.— WALTER Deane, for the Local Flora 
Committee.
