Mr. J. Ball on the genus Leontodon. 13 



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

 ranea cum sequente confnsus. Legi prope Neapolim juxta Castel- 

 lamare. 



Syn. Aj)argia saxatilis. Ten. Diagnosis Reichenbachianus videtur 

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

 cum L. saxatili conjungendum judicavit, sive stirpis Villarsianse 

 omnino ignarus fuit. 



— i. foliis e collo radicis crebris, sinuatis, vix dentatis. Legi in ru- 

 pibus prseruptis 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 piiis rigidis stellatis in- 

 cano-scabris ; scapo interdum versus basin folio unico instructo, 

 8-12 pollicari ; 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 subaequantibus. 



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



ment de V Ain a cl. Jordan. 

 Synonym a ad varietatem spectant. 



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



rosa, achenio paulo minus muricato. 

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



Sadler. 

 Syn. Apargia tergestina, Hppe. A. crispa, 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 diiferent 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. crispus 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 + 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. biscutellcefolius, D.C. Radice fusiformi; foliis lanceolatis, 

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

 trorsum versis acuminatis, obscure viridibus, pilis stellatis obtectis ;
