added note that it is “a dwarf variety, 1'-5' high, with very small 
flowers." ' In the 2nd edition, however, Dr. Gray augmented the 
statement by adding to the White Mountain record “L. Superior, 
and northward” and by stating that the American “ variety ” is “E. 
pusilla, Godet, mss." * Godet seems, though, never to have published 
his E. pusilla, although in a letter to Gray, under date of March 1, 
1854, he wrote: "Votre Euphrasia officinalis alpina (White Moun- 
tains, Coll. Oakes) est une espéce parfaitement distincte de notre 
plante. Je l'ai nommée E. pusilla dans mon herbier.” That Godet 
also named another species in his herbarium Æ. pusilla is indicated by 
the fact that, in his Monographie der Gattung Euphrasia, Wettstein 
cites the herbarium-name £. pusilla Godet as a synonym of E. arctica 
Lange (E. latifolia Pursh, as to the Labrador plant); while the Lake 
Superior plant of Gray’s 2nd edition, where the name E. pusilla was 
published, was also E. arctica; and the plants known to Gray from 
“northward” were partly E. arctica, partly at least two other species, 
E. canadensis Townsend and E. disjuncta Fernald & Wiegand. The 
name E. pusilla, therefore, has not a clear signification nor did the 
publication of it by Gray in a somewhat incidental manner as having 
been applied to a "variety" of E. officinalis give it the standing 
necessary for a specific name. 
This treatment of Euphrasia in temperate eastern America was 
carried unchanged through the next three editions of the Manual, 
but in the Synoptical Flora Gray treated some of the common plants 
of the coast of eastern Maine and adjacent Canada (E. americana 
and E. stricta) as E. officinalis, “perhaps introduced from Europe"; ? 
while the plants known to Gray from the alpine region of the White 
Mountains (E. Oakesii), the shore of Lake Superior (E. arctica), the 
northern Rocky Mountains (E. disjuncta), the Aleutian Islands (E. 
mollis) and “far northward” (E. disjuncta, E. arctica, etc.) were treated 
as var. tatarica, a plant known to the writers only from Eurasia and 
from the eastern counties of Quebec. "This interpretation was fol- 
lowed by Watson & Coulter in the 6th edition of Gray's Manual; 
and, except that in 1873 Reeks, in an obscure publication upon New- 
foundland, had published a new E. purpurea overlooked by the
