DIANTHERA, 



Amb;ricana Water Willow 



Favorite plant with cattle for food along our 

 creeks, producing a large flow of milk. The 

 flowers purplish and the separated cells give 

 appearance of two anthers. Fertilized by 

 butterflies and the so-called snake feeders. 



DICENTRA, 



CUCULI.ARIA Dutchman's Breeches 



Canadensis Squirrel Corn 



The firmly closed two spurred petals would 

 seem to prevent intrusion of insects, but by 

 means of gauze placed over flowers, no seeds 

 are set, proving pollen from other flowers is 

 necessary. The rounded spurs make the first 

 named, as they resemble Dutchman's breeches. 



DIOSCOREA, 



vii.U)SA Yam Root 



The rhizomes are used in a medicinal way 

 and the roots or "yams" as articles of food. 

 A bad name, for the plant is never villous, 

 and often nearly smooth.
