216 Rhodora [NOVEMBER 
Cerastium vulgatum L. Occasional at the north end. On June 
17, 1913, I visited several dense patches in fruit on the west border, 
some distance within the marsh. Each patch was about 10 X 50 
feet in dimensions. I took a single plant and counted from the 
single root 58 stems, the outside ones 194} inches long by measure- 
ment. This is but one instance of the vigorous growth of weeds on 
the marsh. 
Lychnis dioica L. Several vigorous male plants in the northwest 
corner. 
[Ranunculus Cymbalaria Pursh. I have not succeeded in detecting 
this species which formerly grew here. I have a specimen which I 
collected on this marsh on June 26, 1884. My journal for this date 
reads, “ I saw only a few plants by a creek which is quite filled at high 
tide.” This species has doubtless disappeared. 
Ranunculus sceleratus L. Several vigorous plants in a ditch, at 
the northern end. 
Lepidium. virginicum L. Very abundant throughout, especially 
near the river border, and forming dense patches with Juncus Gerardi, 
plants very large. 
Capsella Bursa-pastoris (L.) Medic. A single plant in the middle 
of the marsh. 
Radicula palustris (L.) Moench. Two plants only, one on the mid- 
dle of the marsh, and one on the river bank, midway. 
Hadicula palustris (L.) Moench, var. hispida (Desv.) Robinson. 
A single plant by the river. 
Barbarea vulgaris R. Br., var. longisiliquosa Carion. (RHODORA xi. 
139. 1909.) A large clump on the west border, fruiting profusely. 
Potentilla monspeliensis L. Occasional throughout, springing up 
especially on the mown areas. 
Potentilla pacifica Howell. (Rmopoma xi. 48, 1909.) Very abun- 
dant along the river and ditches and also springing up freely on the 
marsh away from these borders. I have a specimen collected by me 
on this marsh on June 26, 1884, with the note from my journal of the 
same date, “ Abundant in the salt-marsh." 
Rosa rugosa Thunb. Native of northern China, Corea and Japan. 
A thrifty shrub 3 feet high near the north end. 
Trifolium pratense L. Rather abundant on the west side, and 
occasional on the mown areas. 
Trifolium hybridum L. Occasional, especially on the west border.
