172 Rhodora [SEPTEMBER 
When currents are favorable, a steady stream of branches can be seen 
flowing from the lagoons out into the lake. 
A specimen has been sent to the Editor to verify its identity.—

FURTHER WOOL-WASTE PLANTS AT WESTFORD, MASSACHUSETTS.— 
It has been my custom to visit a wool-waste dump near here several 
timesa year. Generally I have found some of the Medicks, Erodium 
cicutarium (L.) L’Hér. and (I regret to name the next) Centaurea 
maculosa, established in two pastures and spreading into mowings 
even to the other side of the road several rods away. 
No wool-waste has been placed here for three years, yet I found in 
June, 1913, two plants quite new to our region, Erodium ciconium L. 
and Trifolium purpureum. Lois., there being a single individual of the 
Erodium and seven of the Trifolium. 
I have learned from Dr. B. L. Robinson the following regarding the 
specimens I sent him: “Of Erodium ciconium L. we have at the Gray 
Herbarium only one specimen from America and that is from ballast 
at Philadelphia, where it was collected by the late Isaac C. Martin- 
dale, in August, 1877. On the sole basis of this specimen the species 
is mentioned in the Synoptical Flora by Prof. Trelease, who revised 
the Geraniaceae for that work. We find no more recent record of the 
species from America. 
Of Trifolium purpureum Lois. there seems to be no record of Ameri- 
can occurrence. These species both come from southern Europe and 
adjacent Asia.” — EmtLy F. FLercuer. Westford, Massachusetts.
