bears a striking resemblance to A. Lindleyanus ; it runs easily into 
forms suggestive of A. sagittifolius, and A. Drummondii ; and it 
grades almost insensibly into the dealate forms characteristic of 
A. cordifolius. A. cordifolius, A. Lowrieanus, and A. sagittifolius , 
as found in eastern Wisconsin, all tend to produce variants with 
pubescent stems, and leaf surfaces pilose below and rough above, 
which are not easily distinguishable from each other, and seem to 
be included under the comprehensive designation of A. Drum- 
mondii. 
Plants of the “intermediate character” above mentioned occur 
in many portions of the state. These are for the most part con- 
sidered as properly assigned to A. cordifolius , although generally 
lacking the roughness of leaf which is given as characterizing 
that species. Certain forms, however, occuring in Milwaukee 
County, with succulent leaves and alate petioles — although less 
broadly alate than in the type — are assigned to A. Lowrieanus. 
A number of singular forms collected October 11, 1902, on the 
wooded slopes of a bluff running down to the Menomonee River 
at Park Hill, just west of the Milwaukee city limits, bear a striking 
resemblance to a specimen of A. choralis E. S. Steele in the her- 
barium of the Field Museum of Natural History. 
A. sagittifolius Wedemeyer 
The writer's herbarium contains specimens of this species from 
Waushara, Outagamie, Calumet, Sheboygan, Ozaukee, Milwaukee, 
Waukesha, Dane, Rock, Racine and Sauk Counties. Those from 
Waukesha and Waushara Counties were collected by Dr. H. V. 
Ogden; those from Sauk County by Prof. A. B. Stout. White is 
the prevailing color of the rays, but plants with tinted rays are also 
found. The species presents many peculiar varieties, some of 
which are extremely hispid. It is probable that the varieties 
dissitiflorus Burgess and urophyllus (Lindl.) Burgess are represented 
in eastern Wisconsin. Many plants with widely divaricate 
branches have the narrow bracts of this species but a manner of 
growth entirely different from the typical form. 
A. Drummondii Lindl. 
This species, in the comprehensive signification above indicated, 
is found all through eastern Wisconsin, from Ozaukee County to
