Scirpus SMITHI IN MassacauserTs.— When the Preliminary List 
of New England Cyperaceae! was issued, Scirpus Smithii Gray was 
unknown from two of the New England States, New Hampshire and 
Massachusetts. Very quickly thereafter Mr. F. W. Batchelder? 
recorded it from the shore of Lake Massabesic in southern New 
Hampshire, and it is now gratifying to report it from eastern Massa- 
chusetts. On September 18 last, the writer, attracted by the report of 
an extensive station for Sparganium lucidum Fernald & Eames, 
Cyperus aristatus Rottb., Hemicarpha micrantha (Vahl) Pax, Xan- 
thium canadense Mill., and other species which are among the most 
local of Middlesex County, joined Mr. A. J. Eames on a trip to Heard's 
Pond, Wayland. ‘These plants were soon found in abundance, as 
well as several which were before unknown from that station. Among 
them is Scirpus Smithii which grew in a shaded mucky shore where it 
was hidden by the taller grasses and sedges. It is interesting that S. 
Smithii should be the only one of the Scirpus debilis group at Heard's 
Pond, for in eastern Massachusetts the members of this group show 
a remarkable tendency to restrict their development to very isolated 
stations. Thus S. Hallii is known in New England only from the 
shores of Winter Pond; 5. debilis, var. Williamsii has as yet a single 
known station (in the world), the margin of Massapoag Lake in 
Sharon, where it-abounds to the exclusion of other members of the 
group; and now S. Smithii is found at its first Massachusetts station, 
Heard’s Pond, where no other members of the group are known. S. 
debilis (typical) is the only plant of the group as yet known from 
more than a single pond-shore, but even that species is so local as to 
be unknown to most of our New England botanists.— M. L.
