broad as body, and distinct dorsal and intermediate ribs : oil- 

 tubes solitary in the dorsal intervals, 2 or 3 in the lateral, 4 

 to 6 on the commissural side : seed-face plane. 



Huachuca Mountains, S. E. Arizona, June, 1887 {Lem- 



mon 392). 



The appearance of the leaves of this species is quite un- 

 usual for Peucedanmn, but its affinities with that genus are 

 clear. The specific relationship is not so clear. Mr. Lem- 

 mon writes that the plant seems very rare. 



' Peucedanuni Plum m era. Short caulescent with a cluster of 



stout widely spreading peduncles (8 to 12 in. high) rising 

 much above the leaves and from a thick tuberous root, 

 glabrous and somewhat glaucous : leaves ternately decom- 

 pound, the numerous crowded ultimate segments very small, 

 oblong, more or less confluent : umbel very unequally 6 to 12- 

 rayed,\vith no involucre, and involucels of numerous lanceo- 

 late acuminate bractlets ; rays i to 3 in. long ; pedicels 2 to 4 

 lines long : flowers white : fruit oblong but usually acute at 

 apex, glabrous, 4 to 4^ lines long, 2 to 2% lines broad, with 

 wings from half as broad as body to fully as broad, and indis- 

 tinct dorsal and intermediate ribs : oil-tubes 2 to 3 in the inter-

California, Sierra Valley, Sierra county, May, 1889, and 

 near Shasta, Shasta county, June 28, 1889 (at both stations 

 by Mr. & Mrs. y. G. Lemmon, 32 and 40). 



This species seems most closely related to P. Nevadense. 



Ligusticum scopulorum Gray. The range of this spe- 

 cies must be extended so as to include Sierra county, Cali- 

 fornia {Lemmon 19), and the coast mountains of Oregon 



{Howell 708). 



Ligusticum Porteri C. & R. was collected in S. Utah in 

 1877 by Dr. E. Palmer (no. 176). 



Ligusticum apiifolium Benth & Hook, has been collected 

 in Pierce county, Oregon (C. V. Piper 644).

 Lake, B. C, at 6500 ft. altitude. Specimens collected on Mt. 

 Rainier, Washington, altitude 5,000 feet {Piper & Smith 629) 

 show smaller fruit than recorded before, some being but \\ 

 lines long ; but they occur along with many of recorded size.
