THE AMERICAN RANGE OF BoTRYCHIUM LANCEOLATUM.!— In recog- 
nizing as a distinct species, Botrychium angustisegmentum,”’ the Appa- 
lachian plant previously described as B. lanceolatum var. angusti- 
segmentum Pease & Moore,’ Professor Fernald has pointed out that 
in Europe true B. lanceolatum is a subarctic or arctic-alpine plant of 
limited distribution, and has discussed its American range as follows: 
“In North America it occurs within the Arctic Circle in Greenland 
(latitude 63° N.) but is unknown elsewhere in the East; in the West 
it extends from the Aleutian Islands to Mount Ranier in Washington 
and the Selkirk Mts. in British Columbia. South and east of these 
mountain stations its occurrence is doubtful, for although often said 
to reach Colorado, it is noteworthy that in preparing his Flora of 
Colorado Rydberg was unable to verify its occurrence there.” Sub- 
sequently 4 Mr. F. W. Hunnewell reported having collected a specimen 
in the Yellowstone National Park, Wyoming, in 1914; and there is a 
Yellowstone specimen in the National Herbarium, collected many 
years before by Frank Tweedy. 
Botrychium lanceolatum occurs in Colorado and Quebec, also, as 
shown by specimens in the National Herbarium. The Colorado 
collections are two: “Mt. Antero, spur of Sawatch Range,” Aug. 1880, 
T. S. Brandegee; and “Glacier Lake, alt. 8,500 ft., on dry gravelly 
slopes composed of disintegrated granites,” July 5, 1914, E. Bethel. 
Mt. Antero, named for an Indian chief, is in the region of Mt. Yale and 
Mt. Princeton. Mr. Brandegee writes that there are three Colorado 
specimens in his own herbarium, marked as collected by him in 1880 
at an altitude of 10,500 feet in the Sawatch range. The Glacier Lake 
specimen of Mr. Bethel is large and complete, and altogether charac- 
teristic. 
The Quebec record rests upon excellent specimens collected by Mr. 
William Palmer, Aug. 17, 1887, among grasses on a sandy beach at 
the mouth (eastern side) of the Mingan River, but a few rods distant 
from the Gulf of St. Lawrence. This extension of range, though 
notable, is not surprising.— Wittram R. Maxon, Washington, D. C.
