(836.) S. Marylandica, Linn.; C. & E. Eev. of K Amer., Umbell, 102. 



Coulter and Eose give the range of this species only westward to

 and references under that species in Part I. belong here.

 the divisions rather sharply cut and toothed, the teeth mucronate- 

 tipped ; umbels unequally few-rayed, with involucre of few leaf-like
