_ This plant has been sent to me from a aumber of points dur- 
ing the past three years and I have collected it twice myself. It 
seems to be fairly naturalized in some regions. As represented in 
the specimens examined, it is readily distinguished from &. Siza- 
pistrum Boiss. by the total absence of the hispid pubescence of that 
species and by its erect longer and subulate-beaked pods. 
In waste places, Southern New York and Pennsylvania to 
Michigan and Virginia. Adventive or naturalized from Asia. 
Also introduced into the West Indies and South America.
