swamp. It grew as you described it in tamarack conditions, and 
was fairly abundant. I took perhaps thirty sheets of specimens at 
this place. One or two of them had two flowers, but I think two- 
flowered specimens are rather rare." 
Not having before heard of such a thing as a two-flowered 
plant of this species, I wrote to Mr. Deam at once to inquire as to 
how they were two-flowered ; whether with the two flowers on two 
separate scapes, or, on one two-flowered scape. My correspondent 
wrote later that he had tried to find his two-flowered specimens 
and could not; and he was manifestly unwilling to venture a reply 
to my query without a new look at the plants. Here, then, there 
is something for future collectors of the plants to look into. 
Professor C. F. Wheeler, now of the Department of Agriculture 
in Washington, but for a quarter-century, more or less, an active 
Michigan botanist, long time Professor of Botany at the Michigan 
Agricultural College not far from Lansing, I find very familiar with 
our Stemless Lady's Slipper as it occurs in the tamarack marshes 
of south-central Michigan. He informs me that its habitat and 
associations in that region are quite those which, in my former.

opposite side of Lake Michigan in southern Wisconsin, though 
with the rather noteworthy difference, that he often gathered it 
in his Michigan region growing in the very midst of the living 
sphagnum itself, where, as the plants were lifted, their white roots 
showed plainly that they had not been in any soil at all, but were 
supported by the watery-spongy sphagnum. I may here remark 
that in the larch swamps of Wisconsin, it was in this watery-spongy 
sphagnum alone that Arethusa and Pogonia grew but not the 
Cyprepidium.

mistake not, former students of Prof. Wheeler.
