MISCHLLANEOUS SPECIES. 
Pa 
Peucedanum bicolor Wats. Coulter and Rose erroneously 
describe this species as to the leaves. The writer’s specimens 
come from Watson's type loeality. The leaves are ternate 
with tripinnate divisions, segments filiform, 1-3” long. ‘They 
should also have put this in the section with P. ambiguum and 
not with P. caruifolium as it is more closely allied to the former. 
Peucedanum bicolor var. gumbonisn.var. This has thesame 
habit as the type, it grows in sticky clay soil on slopes where little 
else will grow, it has the same moniliform roots or string oftubers 
as the type, (not ceespitose as stated by Coulter and Rose) and is 
like it also in the following particulars: Stems 1-1$° high, one to 
few from the same crown, ascending, leafy, glabrous; petiole 
Wholly dilated; rays few, very unequal, 1-4’ long; involucres 
none; flowers yellow, many, small, dense, pediceled; fruit with a 
strong odor, 6” long, 14” wide, truncate at both ends, linear- 
oblong, a little narrower at tip than base, searcely at all narrowed 
below; lateral wings reduced to thick white corky lines, dorsa 
ribs are minute white lines; fruit arcuate a little, in dense heads. 
This variety differs from the type in having ternate and not 
bipinnate segments, the larger ones being 6-12” long, acute, 
linear, not over 1” wide; flowering pedicels almost none, fruiting 
pedicels not over 1” long, stout; oil tubes prominent, large, 
apparently only one in each interval, 2 on the commissure, dor- 
sal ribs evident. Gathered on Monroe Creek, April 20, 1900, 
andin Indian Valley, southern Idaho, July 15, 1899. 
Peucedanum Grayi var. aberrans n. var. Leaf segments fili- 
form, oil tubes interrupted and variable in length except the central
