84 AMERICAN MIDLAND NATURALIST 
My first specimen of A. mesochora were made on hills over- 
looking Lake Goguac near Battle Creek, 19 May. Three days 
later I stopped for a day at Marengo, not far from the other lo- 
cality, and gathered for my herbarium some of the same plants 
I had seen before from the passing train. Long before then 
experience had taught me how to make serviceable specimens 
in antennaria. If others, even those resident in the West had 
taken pains to make anything like fair specimens we should now 
have been able to give some account of the further range of the 
species beyond the limits the one county of Calhoun where the 
type specimens are found. As things are we have not very much 
to definitely add in relation to its distribution. 
MiIcHIGAN. ‘Two years before my discovery of A. mesochora 
it had been collected for E. Nelson’s distribution by the late 
Prof. C. F. Wheeler at the Agricultural College near Lansing. 
Four sheets of this plant are before me, aggregating 10 specimens, 
8 of them fertile. The two sterile ones are feeble and poor. Per- 
haps they were not sought with any attention. The two show 
well the marks of the pappus in the sterile plant. The fertile 
plants also, all but two or three, are indifferent. The one really 
good one is a fertile specimen on U. S. Herb. sheet 390134. On 
the same sheet is a second specimen, at a much earlier stage, 
belonging to some other species. In all the rest of these specimens 
the scales of the fertile involucres are rather too broadly and > 
conspicuously white-tipped. 
More remote from my original stations, but on the same 
parallel, in the extreme western part of Michigan and within 
sight of the shipping of Lake Michigan at Benton Harbor, I col- 
lected again in 1909 a perfect type of this species in the two sexes, 
this on May 27. The plant was common at that point; and it 
was later in the day, and in a different spot, that I detected A. 
umbellata described above. 
Mr. Charles K. Dodge, for the Nelson distribution collected 
some large fertile plants at Algonac on the eastern edge of the 
State which I wish I could refer to the present species, and the 
more because A. mesochora is manifest on the other side of the 
St. Claire River in Ontario; but the involucres in these Algonac 
plants are wrong for the species. Their scales are too little im- 
bricated, their tips too broad and conspicuous, and they show a 
tinge of flesh-color, It is to be hoped that the well known zeal
