recognized as wholly distinct American species,—G. nesophila Holm 
of western Newfoundland, Anticosti and the Mingan Islands; G. 
procera. Holm, a large-flowered plant extending from Manitoba 
eastward to Niagara County, New York; G. Macounii Holm, of the 
Canadian prairles eastward to James Bay; and other endemic and 
very characteristic species occurring from the Rocky Mountains 
to the Sierra Nevada. The Pickering specimen preserved in the 
Gray Herbarium is a dwarf and hardly recognizable individual, but 
in various details it is clearly not the Norwegian G. serrata but belongs 
in the American series of species already ably monographed by Dr. 
Theodor Holm,! who has clearly pointed out many characters separ- 
ating the group of American plants from the European. For want 
of a better place to put it the Pickering specimen had recently been 
tentatively placed by the present writer with the Anticosti and New- 
foundland G. nesophila; and in 1916 Brother Marie-Victorin distri- 
buted as G. nesophila from L’Islet, about forty miles east of Quebec, 
fruiting and somewhat fragmentary specimens which clearly belong 
with the Pickering plant but like it are not satisfactorily identified 
with the Anticosti and Newfoundland material. And finally, thanks 
to the intensive botanizing of Brothers Victorin and Rolland, a 
beautiful series of the plant is at hand from both above and below 
the city of Quebec. "These new collections, showing abundant 
specimens in flower and fruit and in all sizes from small and simple 
individuals to large freely branching plants, at once demonstrate 
that the plant from the neighborhood of Quebec is a thoroughly 
distinct and hitherto unrecognized species with affinities about mid- 
way between G. Macounti, procera, nesophila and crinita. This 
species, with which it is a keen pleasure to associate the name of the 
untiring investigator of the flora of the Province of Quebec who has 
brought together the first adequate representation of the plant, is 
apparently typical of the tidal shores of the St. Lawrence for about 
fifty miles, from Cap Rouge to L'Islet. This species is illustrated 
in Plate 139, kindly prepared by Miss Amelia Brackett of Radcliffe 
College. Brother Victorin states that it *is the only common Gentian 
in the neighborhood of the city of Quebec. It is distinctly a riparian 
species, growing on the tidal shores, often within the reach of high 
tides. I have found it plentifully everywhere I went on the shores. 
It is interesting to note that neither you nor I ever found it from
