140 Rhodora [JuLy 
POTENTILLA PALUSTRIS (L.) Scop., var. VILLOSA (Pers.) Lehm. 
This handsome variety, noted in RHODORA, xi. 48 from the Gulf of St. 
Lawrence, is the common form of the species in eastern Washington 
County, Maine, where it occurs in either fresh or brackish water. 
PorENTILLA PALUSTRIS (L.) Scop. var. SUBSERICEA Becker, 
Deutsch. Bot. Monatsschr. xv. 85 (1897), which has the leaves silky 
but lacks the dense glandular pubescence on the peduncles, petioles, 
etc., was found on the meadows of the Nerepis River at Westfield, 
N. B., the first station known to us in America. 
AGRIMONIA GRYPOSEPALA Wallr. occurs in the alluvium of the 
Nerepis River, Westfield, N. B., and along the Aroostook River, 
Ft. Fairfield, Maine, thus extending its recorded range slightly north- 
eastward. 
VicIA ANGUSTIFOLIA Reichard, var. UNCINATA (Desv.) Rouy & 
Foucaud. This variety with very narrow elongate-linear and truncate 
mucronulate leaflets formed depressed mats on the strand at Pleasant 
Point, Perry, Maine. Similar specimens were collected by Judge J. R. 
Churchill near Tracadie Beach, Prince Edward Island, in 1901. 
These are the only American collections of the variety seen by the 
writers. 
EUPHORBIA SERYPLLIFOLIA Pers. Two forms of this species, one 
with green leaves, the other with leaves blotched with crimson, abound 
in the yard of the Canadian Pacific Railway at Aroostook Junction, 
Andover, N. B., where they are accompanied by the ordinarily more 
common E. maculata L. and E. hirsuta (‘Torr.) Wiegand. 
EUPHORBIA GLYPTOSPERMA Engelm. Abundant in the yard of 
the Canadian Pacific Railway at Hartland, New Brunswick, and in 
less abundance along the railway at Fort Fairfield, Maine. 
ACER RUBRUM L., var. TRIDENS Wood. A large tree with peculiarly 
depressed wide-spreading top was called to our attention by Dr. G. U. 
Hay near his camp at Ingleside Station, Westfield, New Brunswick. 
This proved to have the characteristic foliagé of the var. tridens, 
a variety previously unknown north of Auburndale, Massachusetts, 
its only known New England station (see Rehder, Ruopora ix. 116). 
RHAMNUS ALNIFOLIA L’Her. occurs locally in a rich swamp on the 
Charlotte Road, Pembroke, Maine, near a calcareous outcrop. It 
was also seen in meadows of the St. Croix River below Princeton. 
MALVA SYLVESTRIS L., var. MAURETIANA (L.) Boiss., which differs 
from the typical hirsute M. sylvestris with sharply angulate-lobed
