species which exists. In all the specimens 

 which I possess, the lower L. are bipinnate, 

 and the Lts. -pinaatifid and laciniate.

 awn. Pet. white or pink, radiant, b. 7-9- 

 Pashires. 



2. setulosuE. Lower L. bipinnate. Seg-

5. foliosTis. Stem hirsute at base, rough 

 above. Lowest L. somewhat tripinnate ; others 

 bipinnate: Lts. of all cuneato-ovate, acute, 

 inciso-dentate. General bracts bipinnatifid, 

 equalling umbel; partial linear, entire or 

 tiifid, hispid, ciliate, exceeding umbeUule. Pr. 

 ovoid. Prickles subulate, separate, hardly 

 thickened at base, glochidiate, as long as width

 above, hirsute beneath and on the stalks. Lts.

 short and broad segments. General bracts 

 undivided or trifid, linear, much shorter than 



umbel; partial huear, acuminate, entire or 

 trifid. Pr. ovoid. Prickles dilated at base, 

 minutely glochidiate, about as long as width of 

 fruit. PI. white or pink. b. 6, 7- Shore. 

 MondeUo in Sic. 



7. maximus. Stem and L. -stalks hii-sute. 

 Lower L. tripinnate. Iits. ovate, acute, in- 

 ciso-dentate. Umbel large and of many rays, 

 on a dilated receptacle. General bracts nume- 

 rous, pinnatifid. Segments linear. Outer par- 

 tial bracts trifid or pinnatifid, much exceeding 

 lunbeUule. Pr. ovoid, hairy. Prickles subu- 

 late, separate, glochidiate, much shorter than 

 width of fruit. PL white, very radiant, b. 

 4, 5. Sard. This is froh^ly the origin of 

 the cultivated Carrot. 



8. Jiispidias. Stem covered in lower part 

 v.ath deflexed strig02. Lower L. tripinnate. 

 Lts. cuneato-ovate, obtuse, inciso-dentate. 

 General bracts pinnatifid, segments short ; 

 partial lanceolato-linear, acuminate, entire or 

 trifid. Pr. ellipsoid. Prickles sepai-ate, glo- 

 chidiate, somewhat longer than width of fruit. 

 b. 7, 8. Rochj shores. Cuma. Dieppe and 

 Treport : 'perhaps not the same, hut the French 

 plant appears to he the D.maritimus of With- 

 ering, and of our challcy coasts. 



9. Gingidium. Hairless. Stem erect. 

 Lower L. bipinnate. Lts. somewhat fleshy, 

 shining, cuneato-ovate, inciso-dentate. Gene- 

 ral bracts pinnatifid, segments linear ; par- 

 tial lanceolate, with mde membranous margin, 

 cihate, entfre or trifid, as long as umbeRule. 

 Pr. ovoid. Pricldes subulate, separate, some- 

 what incurved, naked, simple at the top, 

 shorter than width of fruit, b. 6-9. Shores 

 of Italy. 



j8. All Lts. pinnatifido-dentate, with narrow 

 segments. 



y. Stem and L. -stalk hispid. L. sometimes 

 hairy on both sides. D. maritimus of 

 Smith ; B. gummifer of Savi and Gussone. 



5. Stem decumbent, rough. Segments of L. 

 short, lanceolate, mucronulate. D. mariti- 

 mus of DC. and of Gussone {iiot of With- 

 ering). 



Bertoloni inserts the term hairless (glaber) 

 in the specific character, and at the end of the 

 detailed description adds, "tota planta glaber- 

 rima ;" yet he intends it to include B. mariti- 

 mus of Smith, which in my specimens is always 

 rough with hairs. The upper face of the 

 L. is hairless, or neaily so, through all the 

 genus. Bertoloni says the prickles are distinct.
