A. paniculatus Lam. 
A. paniculatus var. simplex (Willd.) Burgess 
A. paniculatus var. acutidens Burgess 
This species is common in wet ground in the neighborhood of 
forests. Some of its forms are not easily identified with any of the 
varieties named in the books. The variety simplex has been col- 
lected in Milwaukee and Sheboygan Counties; the variety acuti- 
dens in Kenosha, Milwaukee and Outagamie counties. Forms 
with secund inflorescence are occasionally met with in Milwaukee 
County. Hirsute forms, suggesting relationship with A . puniceus, 
were collected by J. H. Schuette in Brown County. The rays in 
all cases, so far as observed, are white. 
A. salicifolius Ait. 
A. salicifolius var. subasper (Lindl.) Gray 
A. salicifolius var. stenophyllus (Lindl.) Burgess 
Plants assignable to this species have been collected in Outa- 
gamie, Sheboygan, Ozaukee, Milwaukee, Waukesha and Racine 
Counties. Prof. A. B. Stout has collected specimens in Sauk 
County. The variety subasper has been collected in Sauk, Sheboy- 
gan, Ozaukee and Milwaukee Counties; the variety stenophyllus in 
Ozaukee County. It is only rarely that the rays are other than 
white in the specimens collected in this state. 
A. junceus Ait. 
This species has been collected at the borders of tamarack 
swamps in Sheboygan, Waukesha and Milwaukee Counties. The 
rays are in most cases white, sometimes turning pink with age. 
Extremely delicate forms are found growing in shade, requiring 
support from surrounding growths. 
A. longifolius Lam. 
Collected by J. H. Schuette in Brown County, by Mr. Benke in 
Waushara and Waupaca Counties; by Mr. Finger in Monroe 
County; and by Dr. Ogden in the central portion of Milwaukee 
County. The writer’s herbarium is indebted to the three last 
named gentlemen for specimens. Specimens collected by L. S. 
Cheney in Dane County are in the University herbarium. All
