root, 12 to 18 inches high, simple, rather slender, leafy; leaves 
about 6inches long, very narrow, ligule membranaceous, long 
and pointed ; panicle nodding, lax, open, 4 to 6 inches long, the 
base enclosed by the upper sheath, branches capillary, mostly in 
twos, flowering from the middle or below, mostly simple ; spike- 
lets thin and with a silvery lustre, about 1% lines long, on short 
pedicels ; empty glumes % to 3{ as long as the flower, flat or very 
little compressed, nearly equal, acute, the upper one three-tooth- 
ed at apex ; flowering glume oblanceolate, membranaceous, three- 
nerved, slightly pubescent on the nerves, two-lobed at the apex, 
the awn between proceeding from the upper fourth, twice as 
long as its glume; palet as long as, or longer than its glume,

Euphrasia Officinalis, L. 
The only New England locality cited for this species in Gray’s 
Manual, is “Alpine summits of the White Mountains, N. H.” 
It is also there reported as found at Lake Superior and north- 
ward. . It is now known, however, to occur occasionally on the 
southern portion of Mount Desert Island, where I have seen it in 
grassy places near roadsides. I have also seen it in grassy swards 
on the southern portion of Great Cranberry Island, and also on’ 
Great Duck Island, both lying south of Mount Desert Island. 
Pringle also noted it, in 1879, on the south shore of the St. Law- 
rence River, one hundred miles below Quebec, in the fields near 
the shore.* In all these places it would seem to be an introduced 
plant. : J. Pigak 
[We can testify to finding &. officinalis on Duck Island in 
1880, and can also add that we have found it growing abundant- 
ly along grassy roadsides at Grand Lake, Nova Scotia, and re- 
member seeing it on the slopes of the fortifications at Quebec. 
In Nova Scotia, along roadsides, was also found the Ladies’ 
Mantle, Alchemilla vulgaris, L., which is undoubtedly of Eu- 
ropean origin.—ED.]
