secured on July 22. Various other herbarium specimens indicate 
frequent occurrence of this variety in Western New York, and its 
general distribution must be more or less the same as that of the spe- 
cies, if I am justified in crediting to var niagarensis the U. S. National 
Herbarium sheets numbered and labeled as follows: 
30410 — H. P. Sartwell, Penn Yan, N. Y. 
295054 — F. V. Coville, 10 June 1884, Oxford, N. Y. 
134251 — L. F. Ward, August 1879, Indian River, N. Y. 
249817 — A. P. Garber, 25 July 1868, Greenville, Mercer county, Pa. 
239176 — J. Fowler, 16 August 1881, Sharhott Lake, Ont. 
605631 — J. Fowler, 26 July 1902, Plevna, Ont. 
30407 — F. F. Wood, 28 June 1889, bank of Bad River, Wis. 
30602 — F. F. Wood, 13 August 1891, Barron, Wis. 
131962 — M. S. Bebb, 1870, Fountain, Ill. 
30408 — C. A. Ballard, July 1893, Lake Kilpatrick, Minn. 
Pressed young material can evidently not be determined, as many 
June, and even some July, collections do not seem 
to have the perigynia matured enough to show de- 
terminative characters after being pressed; e. g., 
of three sheets of Sartwell’s specimens in the 
National Herbarium, I care to cite only one as 
showing evidence of representing the variety I 
describe. The original illustration of Dewey's 
seems to have been made from very young mate- 
rial and can easily confuse one in trying to study 
the species in its matured 
forms. 
My only collection 
which I am willing to call 
typical C. Tuckermani was 
found in a water-shed bog 
a short distance north of 
MA at e nih Summit Marsh, North 
rensis. Xj. Spencer, Tioga county, N. 
Y., and is my No. 2583,

collection is represented at "c" in the figures sach ABA —

The species is designated as a plant of “wet meadows" (Dewey),
