the environment is no longer that of the prairies of south-central 
Michigan, bit something very different. We have antennaria 
material—some of it excellent—from those districts suburban 
to Chicago in both states, but no A. mesochora; or at least none 
that is at all genuine. 
WISCONSIN. Passing northward along the lake shore, the 
low and almost swampy-prairie region on which Chicago and its 
suburbs have been builded are left behind, and one traverses 
there in southern Wisconsin, just opposite southern Michigan, 
again a region of elevated and rolling prairie. Except as being 
to the windward of Lake Michigan, and therefore notably 
colder in winter than southern Michigan, the environment is the 
same in the two, and here in Wisconsin we might expect A. meso- 
chora. Unluckily I have access to little evidence in this case. 
Botany is long since moribund in Wisconsin and some other 
neighboring states; and good specimens of Wisconsin plants 
if found in herbaria, are mostly such as were gathered by earlier 
generations. In 1898 I made near Dodgeville and as late as 
20 June—which is too late—specimens of a large antennaria 
“gone to seed’’; but the involucres, not yet withered, are those 
of A. mesochora, and the stature of the plant, also its foliage and 
general aspect are those of that species. No male plant was seen. 
I2. ‘A. OCCIDENTALIS, Greene, Pitt, ii: 322 (21 May, 1898): 
Readily distinguished from A. mesochora by a stouter habit, 
a more herbaceous texture, a less imbricated involucre the scales 
of which have rather wide and conspicuous white tips, and the 
pappus of the male showing but little flattened and distinctly 
serrate bristle tips. This does by no means express all which 
the botanist ,with botanist’s trained and experienced eye sees 
by which we know this plant of the southerly prairie region as 
something other than its northern congener. Apparently the sterile 
or male plant of A. occidentalis is as rare as that of A. mesochora 
is common; yet the oldest specimen of A. occidentalis that I 
have seen, as well as the only one I knew of when first describing 
the species is a sterile one collected by myself as long ago as 1867. 
That I gathered only the male plant at the time may well indicate 
that I did not see the other. The mansion of a Chicago mil- 
lionaire and its spacious grounds and gardens long since came to 
occupy the site where I gathered my specimen forty-four years 
ago. The habitat was an open low sunny hill top just outside
