Mr. J. Ball on the genus Leontodon. 13 



Hab. ill regno Neapolitano et verosimiliter in tota regione mediter- 

 ranea cum sequente confusus. Legi prope Neapolim juxta Castel- 

 lamare. 



Syn. Apargia saxatilis, Ten. Diagnosis Reichenbachianus videtur 

 incompletus, nee satis liquet an vir celeb, verum L. crispum, Vill., 

 cum L. saxatili conjungendum judicavit, sive stirpis Villarsianse 

 omnino ignarus fuit. 



— i. foliis e coUo radicis crebris, sinuatis, vix dentatis. liCgi in ru- 

 pibus praeruptis Insulse Caprsearum prope Neapolim. 



Finding the synonyms and descriptions of authors as to this 

 and the following species to be very discordant, I have described 

 the plants known to myself, and have given them the specific 

 names which I have no doubt they were intended to bear by the 

 authors to whom the original descriptions are respectively due. 



13. L. crispus, Vill. Radice fusiformi ; foliis antrorsum pinnatifido- 

 dentatis, segmentis insequalibus obtusis, e pilis rigidis stellatis in- 

 cano-scabris ; scapo interdum versus basin folio unico instruct©, 

 8-12 poUicari ; involucri subcylindracei foliolis omnibus anguste 

 linearibus, adpressis, vix acutis, 4-5-seriatis, exterioribus cum 

 scapo pilis stellatis illis foliorum conformibus tenuiter adspersis ; 

 achenio longe rostrato, prsesertim superne spinelloso-muricato, 

 dentibus diametrum rostri subsequantibus. 



Hab. in Gallia meridionali. Legi juxta Fauduse, habui ex Departe- 



ment de VAin a cl. Jordan. 

 Synonyma ad varietatem spectant. 



4- © + g. gracilior, superne glaber, foliola involucri minus nume- 



rosa, achenio paulo minus muricato. 

 Hab. in apricis Carnioliae et Istriae. Habui a Fiume e manu Prof. 



Sadler. 

 Syn. Apargia tergestinay Hppe. A. crisp a, Willd. Leontodon his- 



pidum, Scop. 



Not without hesitation I have decided on keeping distinct this 

 and the preceding species. The structure of the involucre seems 

 too far different to allow us to unite these otherwise nearly allied 

 plants. In L. saxatilis the involucre is more lax, the phyllaries 

 broader and more acute, the two inner series nearly equal in 

 length, about twelve in number ; in L. aispus they are longer, 

 much narrower and blunter, and the two inner series are about 

 twenty in number in the normal French plant, rather less nu- 

 merous in variety -f e + g. I must however admit, that it is not 

 satisfactory to rest the distinction of species so far upon the cha- 

 racters of a single organ. 



14. L. biscutellcBf alius, D.C. Radice fusiformi ; foliis lanceolatis, 

 in petiolum attenuatis, subeequaliter serrato-dentatis, dentibus an- 

 trorsum versis acuminatis, obscure viridibus, pilis stellatis obtectis j
