1910] Fernald and Wiegand,— Botanizing in Maine 141 
leaves in being glabrous or glabrescent, in having the leaves more 
obtusely lobed, and in its deeper colored flowers, was found in waste 
ground about the site of an old fire at Pembroke, Maine. The only 
New England material of M. sylvestris seen by us — from Rumford, 
Maine (Parlin), Charlotte, Vt. (Faxon), and Charlestown, Mass. 
(Perkins) — is of this variety. 
(ENOTHERA CRUCIATA Nutt. Open sandy roadside near Round 
Pond, Charlotte, Maine. Previously unrecorded east of the Penobscot 
Valley. 
(ENOTHERA FRUTICOSA L., var. HIRSUTA Nutt. Abundant in dry 
open soil in an old field, Pembroke, Maine; the first station recorded 
in Maine east of the Penobscot Valley, where it occurs in open woods 
on the dry slopes of an esker in Alton. 
VACCINIUM PENNSYLVANICUM Lam., var. ANGUSTIFOLIUM (Ait.) 
Gray. Very characteristic shrubs of this usually northern or alpine 
variety were found on the heath at the base of West Quoddy Head, 
Lubec, Maine. It had been found in 1902, but unrecorded, by a 
party from the New England Botanical Club at Cutler, Maine. 
Lysmacuta terrestris X thyrsiflora. In the boggy meadow along 
the St. Croix River between Milltown and St. Croix Junction, 
Calais, Maine, occurs a Lysimachia which in appearance is intermedi- 
ate between L. terrestris and L. thyrsiflora, and which we consider 
a hybrid between these species. In the foliage and density of the 
raceme the plant is like L. thyrsiflora, but the racemes are long and 
mostly terminal as in L. terrestris, though only one plant in hundreds 
produced inflorescences in 1909. A similar plant was collected with 
L. terrestris by Pres. Ezra Brainerd at Middlebury, Vermont, June 22, 
1880. 
FRAXINUS PENNSYLVANICA Marsh. occurs along the St. John River 
at Westfield, New Brunswick. It is also found at Fort Kent in north- 
ern Maine and therefore presumably throughout the St. John Valley. 
GALEOPSIS 'TETRAHIT L., var. BIFIDA (Boenn.) Lejeune & Courtoir. 
Two forms of Œ. Tetrahit, quite distinct in appearance, were seen in 
Washington County; one with large white flowers was found in only 
one locality near the Eastport Railroad Station, but the other with 
smaller purplish flowers was much more widely distributed. A study 
of herbarium material and of European handbooks shows that one of 
these forms is a well-marked variety of the other, and is so recognized 
in Europe. G. Tetrahit in America may therefore be treated as 
follows:—
