The next and last section of this division is Pseu- 

 c^ocymopterus fC. & R., Rev. Umb. 74 (1888) as pe- 

 rils), but restricted to the first species so far as their 

 limitation went. Tt embfaces C. ligusticoides (Thaspium 

 montanum Gray PI Fend. 57, 1849). It approaches Peuceda- 

 ntim very closely, but the fruit and the habit is much Uke 

 Ligusticum. Feucedanum Kingii has the leaves of some forms 

 of the former and the winged dorsal ribs of the latter, at 

 times, P. juniperinum shows the same thing also, alatum and 

 anomalum also show similar characteristics. This group is 

 characterized by erect and slender stems an inch to a foot or 

 two long, from an erect tuberous-enlarged fleshy root, with 

 few rather small crowns covered with few rather large and 

 somewhat fibrous leaf-sheaths and very few dead petioles; 

 leaves not fleshy nor leathery, rather thin, mostly pinnately 

 deconipound into small or linear apiculate segments, on short 

 petioles ; involucres absent and involucels of filiform to linear 

 elongated bracts ; fruit about 2-3 lines long, nearly oval, with 

 lateral wings not as wide as the body, but obtuse edged as are 

 those on the back, thin, cross section either linear or a trifle 

 wider at insertion and sometimes reduced to a knife-edge just 

 above the insertion and wider above, forming a scarcely no- 

 ticeable ring, dorsal wings either half as wide as the lateral or 

 reduced to raised ribs, and then inseparable from Peucedanum, 

 commisural side either flat or concave. The other form of 

 C. ligusticoides is variety tenuifolius (Thaspium montanum 

 var. tenuifolium Grav PI. Wr. 2 65, 1853). 



Peucedanum. Taking up this genus. Coulter and Rose in 

 their last revision relegate this to synonymy as to North 

 American plants and resurrect the name of Rafinesque, Loma- 

 tium, an untenable name, as there is another Lomatia. To dis- 

 turb such a large genus as this certainly ought to require im- 

 portant reasons. They state that the type of Peucedanum is 

 P. ofi^cinale L. Sp. PL 245. but this is not true, since the types 

 of Peucedanum are P. officinale, P. alpestre, P. Silaue, and P. 

 nodosum. Any one of these species is as much the type of 

 Peucedanum as the other as Linnaeus made no preference. 

 Drude in his revision of the genera of the Umbelhferae for the 

 Pfianzenfamilien, and to whom were accessible all the Euro- 

 pean species, refers P. officinale, macrocarpum, utriculatum, 

 leiocarpum, triternatum to the same section Cervana, under
