 8. incisum, Torr. in Frem. 1st Kep. p. 90. 



Hab. Near San Francisco; in wet grounds. — I find no considerable 

 difference between this plant and the European B. ancjustifolia, ex- 

 cept that the fruit is broader in proportion to its length in the latter 

 than in the former. The specimens in the herbarium of the Ex- 

 ploring Expedition are clearly the same as Slum pusillum of Nuttall, 

 which we have, named by that botanist. It is remarkable that this 

 plant, which occurs in so many places, from Michigan to Florida, and 

 west to the Pacific, should not have been identified until within a 

 few years. 



8. PEUCEDANUM, Koch. 

 1. Peucedanum latifolium, Nutt. in Torr. & Gray. 



Hab. Washington Territory, from the Columbia River westward 

 to the Cascade Mountains. — Whole plant glaucous. Stem 1 or 2 feet 

 high. Petioles 5 to 8 inches long. Segments of the leaves sometimes 

 2 J inches wide and more than 3 inches long. Peduncles a foot long. 

 Rays of the umbel 3 to 7 inches long. The fruit is not mature. 



2. Peucedanum leiocakpum, Nutt., 



Hab. Oregon and Washington Territory; also northward to British 

 Columbia. — In the Botany of Whipple's Report I expressed the
