128 BOTANY. 



F. dissecta, which is a somewhat taller plant, with subsessile fruit and a more 

 persistent several-leaved involucre. The root is very tough and rank and is 

 not eaten by the Pah-Utes. Oregon and Idaho. Abundant from the Washoe 

 Mountains to the Wahsatch ; 5-7,000 feet altitude ; May-August. (460.) 



Peucedanum^ sativum, Benth. & Hook, (Pastinaca, L.) Ruby Valley, 

 Nevada ; introduced. (461.) 



Peucedanum Nuttallii. (P. latifolium, Nutt.) Acaulescent, from a 

 thick cyhndrical root, glabrous ; leaves ternate or bi-temate, the segments 

 ovate or orbicular, 1-1^' in length, obtuse, with a few cuspidate teeth at the 

 apex ; scape 4-12' long, stout, bearing a single umbel of 15-25 unequal 

 rays, elongating in fruit (3-6' long ;) involucre and involucels none ; flower 

 light-yellow; calyx-teeth obsolete; fruit elliptic-oblong, 4" long, with a 

 narrow thin wing ; carpels convex upon the back ; ribs but shghtly promi- 

 nent ; vittee very obscure, 3-4 in the intervals and about 4 upon the com- 

 missure. — A very well marked and distinct species, with a strong anise-like 

 odor. Collected in Idaho by Nuttall and on the Dalles, Oregon, by Major 

 Eaines. Havallah Range, Nevada ; 6-8,000 feet altitude ; June. An older 

 P. latifolium, DC, compels a change of name. (462.) 



Peucedanum geaveolens. Acaulescent, from a thick root, glabrous 

 throughout; leaves bipinnate, the segments linear, qlongated, cuspidate; 

 scape 6-18' high, a little exceeding the leaves; umbels .of 6-20 somewhat 

 equal rays; involucre none; involucel unilateral, of 6-8 linear-lanceolate 

 leaflets ; flowers yellow ; calyx-teeth small but manifest ; fruit 4-5" long and 

 2" broad, oblong, with a rather narrow somewhat thickened but acute mar- 

 gin and irregularly raised or but slightly prominent ribs ; vittse about 2 in 

 each interval and 4 on the commissure ; seed somewhat sulcate upon the 

 back. — Evidently nearly allied to P. triternatum, from which it is distin- 

 guished by its entire want of pubescence, the evident though small calyx, the 

 broader variously winged fruit and the more equally rayed umbel. 220 

 Geyer is the same. Subalpine, abundant in localities and possessing a strong 

 disagreeable odor. Wahsatch and Uinta Mountains ; 9-10,000 feet altitude; 

 July, August. (463.) 



1 PEUCEDAI^UM, L. Very nearly as ia Ferula ; the petals usually more inflexed, with the point 

 more depressed and 2-toothed at the apex ; the wing of the fruit narrower, thicker and with a sharper 

 margin, or dilated and thin hut with the margin nearlj^nerveless, and especially differing in the vittse 

 heing almost always solitary in the intervals ; the flowers are also often white. — These are the distinc- 

 tions drawn hy Bentham & Hooker. It will he noticed that in several of the present species characters 

 occur which render their position doubtful. A careful revision of the genus, as of the genera of the order, 

 with especial reference to American species, is greatly needed.
