First Report on the Flora of IVyouii/i^: 1 1 7 



Ligusticum, sp. 



The plants represented by numbers KUO and 1655 are too im- 

 mature to render determination certain, but Dr. Rose, to whom they 

 were submitted, thinks it probable they are distinct species. 

 Oreoxis humilis, Raf. 



Rare; Cummins, July 30, 1895 (No. 1431). 

 Selinum Grayi, C & R. 



In wet places at high elevations. 

 La Plata Mines, August 21, 1895 (No. 1776). 

 Angelica pinnata, Watson, King's Rep. v, 126 (1871). 

 Infrequent; along streams at 7,000-8,000 ft.

 Peucedanum graveolens, (?) Watson, King's Rep. v, 128 (1871). P. 

 Kingii, Wats. 



The material is scanty and over-ripe, but there is little doubt as 

 to the correctness of the determination.

 Peucedanum nudicaule, Nutt. T. & G. Fl. N. A. i, 627 (1840).

 before the snow is off the ground.

The herbarium contains a single specimen collected by B. C, 

 Buffum in 1892, no locality given. It most probably is from the 

 north-eastern part of the state.
