Plants of Boone County, Kentucky. 141 
Antennaria plantaginifolia (L.) Richards. Dry soil, common. 
(Revision of the original species would probably throw my 
plant into A. fallax Greene, which, according to Mr. Deam, is very 
common in Ind., while he has but one authentic record of A. 
plantaginifolia as now understood.) 
Gnaphalium polycephalum Michx. Dry soil, common. 
Gnaphalium uliginosum L. Not infrequent on river-shores. 
Inula Helenium L. An occasional escape to pastures, etc. 
Polymnia canadensis L. Moist woods, common. 
Polymnia canadensis L. var. radiata Gray. With the last, but much 
less common. 
Polymnia uvedalia L. Fence-rows and roadsides, not common. 
Silphium trifoliatum L. Dry banks, infrequent. 
Silphium perfoliatum L. In rich soil along streams, common. 
Ambrosia trifida L. Abundant in rich soil. 
Ambrosia artemisiifolia L. A very common weed.

Bidens connata Muhl. Along streams, rather common. 
Bidens cernua L. Wet places, common. 
Bidens laevis (L.) BSP. River-shores. 
(I have never felt that this was correct, because of being so 
far out of range. Mr. Deam thinks my plant was B. aristosé 
(Michx.) Britt., which occurs on river-banks in many parts of 
Ind.) 
Bidens bipinnata L. Rich, damp soil; common. 
Bidens trichosperma (Michx.) Britt. Frequent on river-banks after 
the great flood of 1884, but never found above high-water mark.
