Comandra livida, Richardson. Under stunted firs on the sum- 
mit of Mt. Mansfield, Vt. 
Callitriche autumnalis, L. Inashallow bay of Lake Champlain, 
Alburgh, Vt. 
Blysmus rufus, Link. Shore of the St. Lawrence, Temisconata, 
Canada. 
Carex arcta, Boot. Low woods near outlet of Lake Champlain. 
Equisetum palustre, L. Sandy shore of Lake Champlain, Shel- 
burne, Vt. 
Equisetum littorale, Kiihlewein. In several places on the grav- 
elly shores of Lake Champlain. 
Specimens of these two Equista have been examined with the 
greatest care by Prof. Eaton, and those of the latter species corres- 
ponded with the utmost nicety with Milde’s figures and with speci- 
mens from Milde’s own hand. These two plants appear much alike, 
especially when dry, and are likely to be confounded unless sections 
of the stem are made. I may add bythe way that Prof. Eaton 
assures me that the E. littorale distributed by Mrs. Roy from Lake 
Huron is E. palustre, L. ; 
The statement copied into the October No. of the BULLETIN, 
that in no other State but New York is Woodsia hyperborea, R. Br., 
known to exist, needs correction. This species grows in two places 
in Vermont, about Mt. Mansfield and on Willoughby Mountain.

§ 273. Catalogue of North American Ferns.—I have in prepar- 
ation and nearly ready for the printer, a Catalogue of the N. A. 
Ferns (North of Mexico) in the “ Davenport Herb.” Mass. Hor. Soc., 
with notes giving localities, time of collection, names of collectors 
and donors, accompanied by occasional critical remarks, which I 
shall publish, provided I can obtain a sufficient number of subscrib- 
ers to meet the expense of doing so. It will probably make a neat 
Catalogue of about 20 pages, and be a complete and accurate list of 
all the ferns now known to grow within our limits. The price will 
depend on the number of subscribers—probably in no case exceeding 
50 cents acopy. Address Geo. E. Davenport, 8, Hamilton Place, 
Boston, Mass. 
§ 274. Introduced Plants.—In addition to the species reported 
in the September number of the BULLETIN we add the following: 
64. FLAVERIA CONTRAYERBA, Juss. A Chilian plant, first found 
by Mr. Ruger on a wharf at Hunter’s Point, in August. It 
was quite plentiful in a single patch throughout Sept. 
65. Dactyloctenium Aegyptiacum, Willd. Wharf at Jersey City; one 
large clump containing above 100 flowering specimens.—Sept. 
—Oct.—So. States. 
66. Cynodon Dactylon, Pers. With the last.—Sept.—Oct. 
67. LEPTOCHLOA FILIFORMIS, Kunth. With the last.—Sept.—Oct. 
68. Crypsis schenoides, Lam. With Flaveria, at Hunter's Point, a 
single specimen. Cynodon Dactylon was also found there in 
considerable number.—Mr. Ruger.
