94 AMERICAN MIDLAND NATURALIST 
born on a long, dense thyrsus. I have found it growing sparingly 
in meadows along running water. 
FEM. E. S. Steele of the Smithsonian Institution named a few 
years ago one specimen from this state as a new species, and sent 
me his original description of it, in order to enable me to discover 
more material of it. All my attempts in this direction have been 
futile, and probably will be, as the plow constantly overturns 
the prairie and exterminates the wild flowers. By this time hardly 
any prairie is left intact here. I hope that Mr. Steele will publish 
this species some time. 
The specimens from my ‘herbarium used as types for the above 
descriptions show the characters markedly which are ascribed 
to the special varieties. Other specimens will sometimes show 
more or less conspicuous deviations from the rules. And it is an 
occasional occurrence that when two stems arise from the same 
tuber, either one shows an inclination toward different varieties 
or even ‘‘mixed’’ characters. This deterred me altogether from the 
idea of making different species out of my material. I met too 
many specimens that only partly allowed themselves to be forced 
into a “‘system”’ thus adding a second name to Laciniaria scariosa, 
and refused unconditionally to accept another species name.

ADDITIONAL NOTE ON CYPRIPEDIUM ACAULE. 
By E. S. REYNOLDs. 
I was much interested when I happened upon Dr. Edward 
L. Greene’s accounts of the ecology of the stemless Lady’s Slipper 
which appeared in the early numbers of the Midland Naturalist.* 
I am again reminded of his accounts by the finding of this same 
plant in another location which was only slightly referred to in 
one of the “additional’’ notes. Dr. Greene quotes from Mr. 
Skeels as follows, “It is also found, but not as plentifully, at Mill 
Creek in the same county, on the summits of sandy ridges, under 
pine and hardwood trees.’”’ To me the typical situation for the 
plants has always been under pine trees in a somewhat open wood.
