1901] Barry,—Habenaria Hookeriana oblongifolia 237 
still abundant along the borders of the deep swamps east of 
Maranocook. 
Mr. Davenport's paper and this give some idea how rich the 
region is in ferns. I might mention further, that Zsoéfes is common 
about the shores; and in a brook running into the arm of the lake 
east of the Maranocook station Marsilia quadrifolia can be found. 
I have an idea that the latter is a newcomer, as I never saw it in 
this place until 1896, and it has become more abundant each year 
since. I wish that members of the New England Botanical Club 
might be induced to botanize further about Lake Maranocook.

HAMPSHIRE. — Habenaria Hookeriana oblongifolia ascribed to New 
York and Canada by Gray's Manual (edition of 1889), has been 
found in considerable numbers in a patch of woods near the West 
Campton schoolhouse. "Leaves measured about two and one-half 
inches by five and one-half. Only one specimen was found in flower.

LYCOPODIUM CLAVATUM, VAR. MONOSTACHYON IN NORTHERN 
Maine. — The typical form of Lycopodium clavatum, L., has two or 
more spikes upon each peduncle. The number varies somewhat 
without changing the habit of the plant. The case, however, in 
which the two spikes are regularly replaced by a single one gives rise 
to a rather striking form or variety, which is the better marked from 
the fact that the single spikes are of greater size than those which 
compose the pairs in the typical form. The single-spiked variety 
was briefly characterized by Hooker (Fl. Bor.-Am. ii. 267) from the 
Rocky Mountains of British America, as var. monostachyon, but has 
been little known and usually omitted from general treatments of the 
American Pteridophytes. However, Prof. J. M. Macoun in his Cata- 
logue of Canadian Plants, v. 290, records the variety from Little 
Tobique Lake, New Brunswick (G. U. Hay), Prince Edward’s Island 
( F. Macoun), and Blood-vein River, Lake Winnipeg ( F. M. Macoun). 
The first station for the variety in the United States was reported by 
Mr. M. L. Fernald last June (RHODORA, iii. 169) on the basis of the
