A. concinnus Willd. 
Narrow-leaved plants with pubescent branches, small heads and 
pale rays, from woods near Whitefish Bay, Milwaukee County, 
may be assigned to this species, which is characterized by Gray 
as an ambiguous one. These specimens strongly suggest hybrid- 
ism between A. laevis and a hairy form of A. lateriflorus. Some 
broad-leaved plants from Milwaukee and Sheboygan Counties 
have similar small heads, pale rays and pubescent branches. 
A. ericoides L. 
A. ericoides var. villosus (Michx.) T. & G. 
A. Pringlei (Gray) Britton 
Mr. H. C. Benke has contributed specimens of A. ericoides, from 
Waushara County, to the Milwaukee Public Museum. The 
variety villosus has been collected by Professor Stout in Sauk 
County. A . Pringlei grows on the rocks, and more luxuriantly on 
the bank above the rocks, at the Dells of the Wisconsin River in 
Columbia County. Plants intermediate in character between A. 
Pringlei and A. polyphyllus Willd. have been collected at North 
Bay, in Door County, by Mr. Howland Russel, Dr. Charles F. 
Millspaugh, of the Field Museum of Natural History, and by the 
writer. Some of these have hairy stems. Specimens of similar 
indefinite character were collected by Mr. Schuette in Brown 
County. 
A. amethystinus Nutt. 
Mr. S. C. Wadmond’s herbarium contains a fine specimen of 
this species which was collected in Racine County. The writer 
has not seen any other specimen from this state. Quite a number 
of specimens in the Field Museum of Natural History, from various 
localities outside of Wisconsin, bear the label A. amethystinus, 
but only two of them seem to the writer to belong to this species. 
The others are rigid and harsh, and, although not apparently 
glandular, may belong to the variety rigidulus Gray of A. ob- 
longifolius. 
A. multiflorus Ait. 
A. multiflorus var. exiguus Fernald 
The species is widely distributed in eastern Wisconsin, but is 
apparently of rare occurrence in Milwaukee County. The variety
