A. hirsuticaulis Lindl. 
The plants here assigned are characterized by greatly elongated 
* linear leaves, with entire, or nearly entire, margins, and seem suffi- 
ciently distinct from any of the foregoing to be taken out of the 
species lateriflorus. Such plants have been collected in Ozaukee 
and Milwaukee Counties. The writer has similar specimens from 
Lorain and Ashtabula Counties in northeastern Ohio. 
A. missouriensis Britton 
Under this name is included a group of plants with pubescent 
stems, oblong-lanceolate leaves narrowed at both ends, short 
branches and short-pediceled heads, intermediate in character be- 
tween A . lateriflorus and A . Tradescanti, which do not seem to be 
referable to any of the varieties of A. lateriflorus (Milwaukee and 
Ozaukee Counties). 
A. Tradescanti L. 
A. agrostifolius Burgess 
The first of these two species has often been treated as a sort of 
refuge, or catch-all, in which might be gathered a number of waifs 
of various descriptions which could not without some degree of 
violence be included within the elastic limits of A. dumosus, A. 
vimineus, or A. lateriflorus , on the one hand, or of the other species 
of the paniculatus group on the other. It is treated in this way in 
the Synoptical Flora and in the sixth edition of Gray’s Manual. In 
the New Manual it is said that “some forms approach No. 39” — 
A. vimineus — “others differ from A. paniculatus only in the smaller 
heads and shorter rays.” The group here included under this 
name embraces a series beginning with slender plants with closely 
ascending branches,, medium-sized heads and narrow inflorescence, 
followed by others of a more divaricate appearance, and ending 
with loosely branching forms with narrow leaves, and heads scat- 
tered at the ends of slender branchlets. The species is found in 
damp soil at the edges of grassy marshes, in both wooded and 
prairie districts from Kenosha to Outagamie and Iron counties. 
Extreme forms, with very narrow grasslike leaves, from Waukesha 
County, are referred to the species agrostifolius as described in the 
Flora of the Southeastern United States.
