FLOWEEING PLANTS AND FERNS OF INDIANA. 9G1 



E. perfoliatum L. Common Thoroughwort. Boneset. 



Abundant in low, wet grounds throughout the State. It appa- 

 rently reaches its best development in rich soils. No plant is 

 more generally known and its use as a household remedy is, or 

 has been, so universal as to give it the popular name of "Ague 

 Weed" in many parts of the State. 



Flowers from July until the heavier frosts.

 and Vigo (Blatchley); Fayette (Hessler); Daviess (Clements); 

 Putnam (MacDougal); Noble (Van Gorder); Jay, Delaware, Ran- 

 dolph, and Wayne (Phinney); Clark (Baird and Taylor); Dear- 

 born (Collins); Franklin (Meyncke); Gibson and Posey 

 (Schneck); Kosciusko (Coulter); Knox (Spillman); Hamilton and 

 Marion (Wilson); Steuben (Bradner). 



E. A.GERATOIDE8 L. f. White Snake-root. Milk- sick Weed. 



Usually found in rich soil in woods, extending also into the 

 open. Its best development is found, however, in shaded places. 

 In the southwestern counties of the State the specimens are al- 

 most without exception pubescent instead of smooth. 



Flowers from July until October. 



This species is very commonly associated in the popular mind 

 with the occurrence of milk sickness in cattle. There seems no 

 justification for the belief, and the Department of Agriculture 

 does not include it in the list of plants "known or suspected to 

 be" injurious to stock.

E. coelestinum L. Mist-flower. 



Rather abundant in the southern counties of the State, where it 

 is found in rich, open woods. It is the most delicate species of 

 the genus and is coming into somewhat extended use as an orna- 

 mental plant. 



Flowers from July until in October.
