Medicinal Plants of Commercial Importance, the United States 

 Department of Agriculture reports on a wide range of wild 

 plants used in the preparation of medicines. Many wild plants, 

 some of them weeds, some attractive wild flowers such as yellow 

 lady's slipper and trailing arbutus and others; important forest 

 trees, as the white pine, oak and ash, have long been used in 

 the practice of medicine. In this bulletin 128 plants of medicinal 

 value, or reputed value, are described and methods of handling 

 for commercial purposes are indicated, but nothing is said re- 

 garding the medicinal values. Accompanying each description 

 is a picture of the plant. 



Dr. Elmer D. Merrill, director of the New York Botanical 

 Garden has been made a professor at Columbia University. 

 The University continues to grant credit for courses taken and 

 work done at the Garden.
