nemone nudicaulis, n. sp.—I wish to direct the attention of any of our 
botanists, who may next summer be visiting Lake Superior, to a singular Anem- 
one. which grows in bogs and on banks near the water at Sand Bay, Minne- 
sota, very near lat. 48°, and in or near the Canadian boundary. All I know of 
it is from a specimen sent to me in a letter, dated August 8, 1870, from Mr. 
Joseph C. Jones, then of the U.S. Steamer Search. He wrote that the plant 
was found growing in mossy ground, close to the water’s edge, and also in the 
bogs, and that it grows in the manner of Coptis trifolia. I believe it has filiform 
root stocks, like those of Anemone Richardsoni, and the radical] leaves are so like 
those of that species that I inadvertently mistook the plant for that species. 
But the involucre consists of a single petiolate leaf, very like the radical, or else 
is wholly wanting. And the akenes are tipped with rather short and hooked 
_ very unlike the long ones of ae nore Arctic species. A flowering 
is a desideratum.—Asa GRA 
rsion of some tree sasite: inate twenty-five rods to the north- 
west of my foot-path on the lawn, there are two large white_birch trees, still 
holding fruit of the last summer. Along the depressions of foot-steps and the 
mark of an occasional sleigh in the snow may be seen large numbers of birch 
seeds, looking as though some one had scattered bran on the snow. Most likely 
many other seeds went further, as there was fair sailing beyond. 
For some years past I have often observed the distribution of the winged 
fruits of the tulip-tree, of which there are several on our lawns. In autumn 
part of the fruits drop off, falling near the tree, but even in the grass and weeds 
every wind tosses them a little further on. Before snow came this year there 
were certainly many of them ten rods from the nearest bearing tree. When 
the snow comes others are torn from the trees and may often be seen for a quar- 
ter of a mile going before the wind on the snow, which may be only very
