ANTENARRIA IN THE MIDDLE WEST 85 
of Mr. Dodge will impel him to investigate this plant, and find 
if possible the male of it. 
Mr. O. H. Farwell sent me from Detroit in 1879 a fertile plant 
to which I could assign no name. I can not now with any con- 
fidence refer it to A. mesochora, the tips of its bracts are too broad 
and conspicuous. Good specimens taken at the right time, and 
of both sexes, are in requisition from about Detroit. 
ONTARIO. Professor John Macoun: in 1901 sent me good 
fertile specimens of this species from extreme western Ontario; 
one from “Pastures at Leamington, Lake Erie,’’ and one from 
“Point Edward, Lake Huron.’ From as far to the eastward 
as Saint Catherines some one whose name does not appear gathered 
antennarias for the A. Nelson distribution, some of them fair, 
most of them poor, many sheets of which were issued under the 
name of my A. ambigens, though none represent it. The best 
sheet before me of this St. Catherines material, U. S. Herb. n. 
390130, I should like to refer to A. mesochora on account of its 
involucral scales being as narrow as in that, and almost as slightly 
white-tipped; but the plant is rank. Its heads are much too 
large and are loosely corymbed. Moreover the scales themselves 
are almost as little imbricated as in the small plants pub- 
lished above as A. umbellata. The sheet next to this in U. S. 
Herb., n. 390131, from the same place, has two small male plants. 
They are insignificantly small by the side of the female plants 
of the other sheet. The heads are but four and are sessile. The 
pappus in these male flowers is that of A. mesochora. Should 
these two sheets of the distribution be proven to be mates, i. e. 
to represent one species, then there would be no doubt about the 
necessity of receiving it as a new one. But as I said before, this 
anonymous gathering from St. Catherines’, all of it sent out under 
the wrong name, is altogether a sad mixture of things utterly 
dissimilar. 
INDIANA and ILiinors. I should, I think, be sure of find- 
ing A mesochora in northern Indiana, especially. eastward, and 
near the Michigan boundary, but most of those sections are little 
or not at all explored botanically, and I have no record to make, 
from the goodly number of herbarium sheets at hand, of this 
species for Indiana. As one follows the southern shore of Lake 
Michigan around, across the northwestern corner of Indiana 
and into northeastern Illinois, both soil and climate change notably;
