A genus of 6 species belonging to the western plains and mountains. 
It seems best to keep out of Lomativin the six following species, which have 
heretofore been placed under Peucedanwn. They have always appeared anom- 
alous in Peucedanuin (Lomatinn), and some of our best botanists haye treated the 
earlier species as very distinct. One of them was considered a generic type by 
Nuttall, under the name which we have adopted aboye. Dr. Gray associated it 
with Sesed/, while some of the recent collectors have contended that it was not con- 
generic with our so-called western species of Peucedanwn. It differs from Lomatium
