in the only known station in the state. Other rare plants growing 
there are Woodsia glabella, Polystichum Braun, Carex scirpoidea, 
Saxifraga Aizoon, three-toothed cinquefoil, Potentilla tridentata, 
Juncus trifidus, Solidago Randii'and S. Cutleri, Betula alba var. cordi- 
folia and a mountain ash with characters of both Pyrus americana 
and P. sitchensis. The business meeting was held in the evening at 
the Brandon Inn and twelve new members were elected. 
The second day was spent in a drive to Silver Lake and back by 
Lake Dunmore. Near the former lake the road ran through a beauti- 
ful glen full of fine specimens of Goldie’s fern, Aspidium Goldianum 
with a little Asplenium angustifolium, and in other woods near by 
was a profusion of Corallorrhiza maculata. Lunch was eaten on top 
of a mountain between the two lakes, from which, although it was of 
no great height, a splendid view of the Adirondacks and Lake Cham- 
plain was obtained. Silver Lake lies one hundred feet higher than 
Lake Dunmore and the stream that connects the two comes down in a 
series of cascades and the beautiful Llana Falls, which were visited. 
About thirty-five members of both clubs were in attendance and 
although the weather was very hot the meeting was a successful and 
enjoyable one, and thanks are due to Mr. D. L. Dutton, the local 
member of the committee, who did so much to make it a success.—

NOTES ON THE GENUS CIRSIUM. 
B. L. ROBINSON. 
In the nearly related genera Cirsium, Cnicus, and Carduus, groups 
which have been subjected by various authors to widely different 
limitation, the specific nomenclature has naturally become much 
involved. In attempting to reorganize the material of these genera 
in the Gray Herbarium and to bring the naming into harmony with 
recent ideas of classification and nomenclature, I note with regret 
that an unfortunate error was made in the seventh edition of Gray’s 
Manual (p. 857). Our Atlantic American yellow thistle appears there 
under the name Cirsium spinosissimum (Walt.) Scop., a binomial 
of mixed authority and not applicable to the plant in question. Just 
how this slip occurred cannot now be ascertained. It may be said in
