everywhere a somewhat different dress. It is often much reduced 
in size, and everywhere there is a peculiar whiteness to its herbage 
due to a greater density and whiteness of its woolly indument. 
Very commonly, too, it grows on elevated and even somewhat 
sandy or gravelly knolls, rather than in such low and even moist 
pasture lands as it is apt to choose in New England and south- 
ward. On the eastern edge, however, of the prairie country, the 
plant is so little unlike that of Pennsylvania and Maryland, that 
one is constrained to let it pass for the same; and the transition 
to the more differentiated white form of northern Illinios, southern 
Wisconsin and eastern lowa is gradual; meanwhile one discovers 
little in the inflorescence or floral characters to mark the plant 
as specifically distinct. The large number of herbarium sheets 
before me are mostly of rather poor material; but the enumeration 
of them, with the special localities, may be of service to those 
in the field, and may incite some to better field work than has 
yet been done in this direction. 
Micuican. O. A. Farwell, Detroit, 14 May, 1898; a single 
pistillate plant very stout and low, only 3 inches high, cluster 
of 6 large heads, labelled A. campestris by Mr. Farwell, certainly 
not that, yet hardly referable to A. neglecta. Also “Woods in 
Detroit,’ 19 May, 1907; sheet of 7 specimens, 5 fertile all too 
stout and low for good A. neglecta, leaves too large and long. 
Again ‘Open fields, Detroit,” 14 May, 1898; 4 specimens, one 
male, all slender, the male with inflorescence dead and dry, the 
females barely past flower, all this normal western A. neglecta, 
that is, not as tall, more whitened than the eastern. Lastly 
“Moist-sandy places near Ypsilanti,” 16 May, 1901; plants 
all male, passing out of flower. 
Charles K. Dodge. Port Huron, 18 May, 1901; quite slender © 
normal western form, female and male. 
Edw. L. Greene. Marengo, 22 May, 1902; 4 specimens 
female and male, all so nearly matching those collected by me in 
the District of Columbia in the year that I published the species, 
even to the racemosely arranged heads, that 1 can not doubt 
the identity of the two. Also this is the only really good sheet 
of this plant which I have seen from the West. The majority of 
collectors gather and send out such miserable stuff, that he who 
is long used to be perplexed by the scraps and fragments, will 
be apt to use his opportunity when in a new field by making
