Last, and in size surely least, was Lemma perpusilla, which covered 
the surface of a small and treacherous kettle-hole pond in a pasture. 
This species is credited to “Massachusetts (Clark)” without further 
data, in Thompson’s monograph on Lemnaceae. There are no other 
records given from New England. The indefinite printed record 
is thus confirmed and made definite, and a new species added to the 
Local Flora list. Prof. M. L. Fernald collected specimens of this 
plant in Barrington, R. I., May 30, 1911, on the New England Botani- 
cal Club Field Day, thus adding a new species to the Rhode Island 
Flora. 
In closing it may be well to call attention to the conspicuous lack 
of native Leguminosae. Aside from Lathyrus maritimus, the only 
species I noticed were Baptisia tinctoria, Lespedeza Nultallii, L. hirta 
and L. capitata. 
In general, the flora of Duxbury is that of seashore and sand-plain, 
with oak and pine woods, red maple and Chamaecyparis swamps. 
There are many wanderers northward from Plymouth and Cape 
Cod, but yet the flora is decidedly different from that of the morainal 
region and warmer shores only a few miles south.

A Seconp STATION FOR CYPERUS Gmavim IN Essex County, 
MASSACHUSETTS.— When the Committee on the Local Flora reported 
in February, 1911, upon the occurrence of Cyperus in the Boston 
District, C. Grayüi was known within the area only from Plum Island 
and "never reported at any other station north of Plymouth." It 
may therefore interest students of our local flora to know that the 
species occurs upon the sand dunes at Ipswicb. While crossing the 
dunes with a party of students upon October 12th, I found a single 
small colony of not more than half a dozen plants. They had all 
fruited well and most of the achenes had fallen, so that the colony 
(presumably of recent derivation from Plum Island) is likely to in- 
crease. A specimen was taken for the Club Herbarium and another 
was collected by Mr. Harold St. John.— M. L. FERNALD, Gray

of this plant from Wayland, Mass. (Ruopora, xiii. 172) leads me to
