2. Gnaphalium Macounii Greene. (Gnaphalium decurrens Ives.) 

 Winged Cudweed. Map 2088. This is a northern species. May specimens are 

 from open, sandy woods and I found a very sandy, fallow field of about five 

 acres that was covered with old-field balsam and this species. This species 

 was rare and found in the moister situations. The plants were much taller 

 and, in most instances, with several branches from near the base that 

 were almost as large as the central stem.

3. Gnaphalium uliginosum L. Low Cudweed. Map 2089. A rare or 

 infrequent plant throughout the state. It is usually found in dried-out 

 muddy places, such as hog wallows in lanes, in open woods, and along 

 river banks. 



I believe this species and G. obtusifolium and G. purpureum are rapidly 

 spreading since their habitat is becoming more frequent. 

 Newf. to Sask. and B. C, southw. to Va., Ind., and Colo. 



4. Gnaphalium purpureum L. Purplish Cudweed. Map 2090. This 

 species prefers a dry, sandy soil and is more or less frequent in fallow 

 fields and open woodland in the southern half of the state, becoming infre- 

 quent to very rare in the northern half of the state but being rapidly 

 introduced.

1. Inula Helenium L. Elecampane. Map 2091. This plant has 

 medicinal qualities and was commonly cultivated by the pioneers. It has 

 escaped in all parts of the state to roadsides, pastures, and open woodland.
