longifolius and A. paniculatus var. simplex. Such forms are not 
uncommon in Outagamie, Sheboygan and Milwaukee counties. 
Similar forms, but with much more pubescence, were collected by 
J. H. Schuette in Brown County. 
A. umbellatus Mill. 
A. umbellatus var. pubens Gray 
A. umbellatus var. latifolius Gray 
This species has a wide distribution in Wisconsin. Typical, 
narrow-leaved forms, from Dane and Vilas Counties, are contained 
in the Wisconsin University herbarium. The writer has similar 
plants from Kenosha and Milwaukee Counties. Mr. Benke has 
collected the variety pubens in Wood County. Plants from Outa- 
gamie and Kenosha counties, with short, broad leaves, are assigned 
to the variety latifolius. Many plants from Milwaukee County 
are characterized by leaves of unusual length and unusual breadth. 
Similar plants from Columbia and Lincoln Counties are in the 
University herbarium. 
A. linariifolius L. 
Collected by the writer only in Sauk County, but known to 
have a much wider range in the state. Not found, so far as known, 
in the eastern tier of counties. 
A. ptarmicoides (Nees) T. & G. 
A. ptarmicoides var. lutescens (Hook.) Gray 
The typical form of this species has been collected by the writer 
on the prairies of Racine County and on the rocky walls of the Wis- 
consin River in Columbia County; by Dr. Ogden in Waushara 
County; and by Mr. Benke in Wood and Waupaca Counties. 
There are specimens from Portage and Burnett Counties in the 
Milwaukee Public Museum, and one from LaFayette County in 
the Wisconsin University herbarium. The latter has also a speci- 
men collected by I. A. Lapham, without date, credited to Mil- 
waukee County, but whether from the present limits of the county 
cannot now be determined. The species is given in Wheeler’s 
and Russel’s lists of plants of Milwaukee County, but no specimen 
from this county has been preserved. It is not unlikely, however,
