 form." (Hansen.) 



20718. Medicago falcata. 



From Omsk, western Siberia. "(No. 198.) The Siberian alfalfa as 

 found wild at Omsk. In my Siberian investigations I learned that as 

 found wild upon the Siberian steppes this is a valuable forage plant in re- 

 gions where the mercury freezes sometimes without snow ; that it is green 

 very early in the spring ; that it endures severe drought ; that it does well 

 upon soils underlaid with hardpan ; that it is considerably resistant to 

 alkali ; that it flourishes where common alfalfa from Europe winterkills ; 

 that the Siberian form of this species is so much superior to the Euro- 

 pean form in hardiness and other desirable characteristics that to go by 

 the botanical name only is very misleading. The present sample is from 

 hay cut from wild plants before my arrival." (Hansen.) 



20719. Medicago falcata. Yellow lucern. 



From Omsk, Siberia. "(No. 199.) This sample I picked from wild 

 plants in the dry steppes near Omsk late in the fall when there was a 

 little snow on the ground. I found the plants held their own perfectly 

 with other native plants in the compact prairie or steppe sod. Omsk is 

 in latitude 55°." (Hansen.)
