furrows. Thus constituted/ this curious genus comprises some fifteen 

 species, 2 herbaceous, perennial, often spinous, natives of southern 

 Europe, the Levant and northern Asia. The leaves are decompound- 

 pinnate or dissected, and the compound umbels are terminal, accom- 

 panied by involucres and involucels whose bracts, indefinite in number, 

 are often hardened and spinescent, hke the pedicels of the sterile 

 flowers. 



III. PEUCEDAN SEKIES. 



The flowers of the Peucedans ^ are hermaphrodite,* regular or 

 nearly so in the centre of the umbellules and irregular at the peri- 

 phery. The receptacle is, in form, a deep sac, much compressed 

 from front to back, and the 



margin of its mouth bears the Peucedanu.n Oreoselimcm. 



perianth and androecium. The 

 calyx is nil or represented by 

 five small teeth, one of which 

 is posterior and two are ante- 

 rior. The petals, alternate 

 and the same in number, are, 

 in the irregular flowers, the 

 more developed as they are anterior ; they are oboval, attenuate at 

 base, with the summit pointed and inflexed ; which makes them 

 appear, as in the Carrots, emarginate or bilobed. The five stamens, 

 alternating wdth them, are inserted below the salient, entire or undu- 

 late, crenelate margin of the depressed- conical stylopod. The styles, 

 longer or shorter, are generally subulate. The ovary, adnate to the 

 cavity of the receptacular sac, which it entirely fills, is inferior, 

 bilocular, and encloses in each cell a descending anatropous ovule,
