BOTAKY. 
F. dissecta, wliicli is a somewliat 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 AVahsatch ; 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 cylindrical root, glabrous ; leaves ternate or bi-ternate, the segments 
ovate or orbicular, in length, obtuse, with a few cuspidate teeth at the 
apex ; scape 4-1 2^ 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 slightly promi- 
nent ; vittffi 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 
Raines. Havallah Range, Nevada ; 6-8,000 feet altitude ; June. An older 
P. latifolium, DC, compels a change of name. (462.) 
Peucedanum graveolens. Acaulescent, from a thick root, glabrous 
throughout ; leaves bipinnate, the segments linear, elongated, 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 ; vittae 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 peucedanum, L. Very nearly as iu 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 but with the margin nearly nerveless, and especially differing in the vittse 
being almost always solitary in the intervals; the flowers are also often white.— These are the distinc- 
tions drawn by Bentham & Hooker. It will be 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.
