NATURAL HISTORY OF PLANTS. 



Peucedaniim Pdlimhia. 



Feucedanum (^Bubon) 

 Galbanwn. 



Selinoides,^ which comprises herbaceous species, with numerous invo- 



lucral bracts. The invohicre is the same in Cervaria," in which, on 



the other hand, the margin of the fruit is thicker and narrower. 



These two marginal conditions of the carpels are 



met with in the section Eupeucedanum,^ where the 



involucre disappears, as in the Parsnip. In Tom- 

 masinia,'^ the fruit is in con- 

 struction hke that of the Seli- 

 noides ; but the two wings of 

 the same side fall off early, 

 which gives the fruit some Re- 

 semblance to that of the An- 

 gelicas, of which Tommasinia 

 has also the fohagej^ and which 

 has given its name^ to the 

 section of the genus Peuce- 

 dcmuvi in which it has been 

 ranged. The calyx is deve- 

 loped, like that oi Archemora^ 

 and Tiedmannia,^ American 

 Peucedans whose fruit has 



rather large, but contiguous wings. 



Thus conceived,' the great genus Peucedanum comprises about a 



Fruit (f).

' Gjehtn. loc. eit. — DC. he. eit. 176. — It ap- 

 pears to us as diflSoult to separate generically 

 from Fupeueedanum as from the Peucedans or 

 even from Ferulago, Palimbia (Bess. Enum. Fl, 

 Volhyn. 55. — DC. Prodr. iv. 175), not only the 

 greater number of species of this genus which 

 have heen already referred to Peucedanum {Pa- 

 limMoidea Boiss.), hut even the type itself (fig. 

 90), that is P. salsa Bzss. {Sion salsum L. p. — 

 Ferula salsa Ledeb. —Agasyllis salsa Spbeng. — 

 Peucedamim redivivum Pall.) which the most 

 recent authors have preserved as a distinct genus 

 (BoTss. Fl. Or. ii. 982). Its vittse are not 

 solitary in the furrows ; which brings this plant 

 also near most of the Ferulas. 



* Bbbtol. Fl. Hal. iii. 414. Boibsiek l^Fl. Or. 

 ii. 979) preserves this genus distinct, believes it 

 identical with Xant/iogalum Lallem. (p. 98, 

 note 3). Ormosolenia Taubch {Flora [1834], 348), 



approaches both this section of Fupeucedanum 

 and Pastinaca, 



* It is nearly the same as Porphyroseiaa 

 decursiva Miq. {Ann. Mus. Lugd.-Bat. iii. 62), 

 the fruit of which has been compared to that of 

 the Angelicas and which in fact much resembles 

 it, so far as we have been able to judge from un- 

 ripe specimens, but the mericarps are united at 

 the margins before maturity and leave between 

 them on each side a false cell, as in Pastinaca, 

 &c.
