lO Mr. J. Ball on the genus Leontodon. 



foliis incano-virentibus, exterioribus spathulatis, sequeutibus ob- 

 loiigo-lanceolatis, antrorsum dentatis ; involucri foliolis lineari-acvi- 

 minatis ; achenii suberostris costis muricatis, radiorum pappi plu- 

 mulis deciduis. 

 Hah. in Apennino Apuano. In verticibus Pagna della Croce* et 

 Tambura, mense Julio, 1844, florentem, banc stirpem detexi, ite- 

 rum legi, mense Maio, 1848, juxta scaturigines Frigidse in iisdem 

 montibus, specimina nova prioribus omnino conformia. 



Although this species much resembles L. hastilis A, I cannot 

 doubt of the necessity for distinguishing it from all the forms of 

 that species. Independently of the remarkable and anomaloiis 

 character of the pappus^ common to all the specimens from the 

 different localities above mentioned, the hooked bi-anches of the 

 forked hairs, the narrower and more pointed phyllaries, and the 

 rougher ribs of the fruit, furnish points of distinction amply suf- 

 ficient to justify its introduction as a new species. The root also 

 appears to resemble those of the two following species, and to 

 indicate a transition from the horizontal abrupt rhizoma of the 

 species hitherto described to the fusiform root which charac- 

 terizes the following section. 



8. L. Fillarsii, Lois. Radice subfusiformi, obliqua, parce fibrosa ; 

 foliis in&equaliter pinnatifidis, lobis oblongis anguiatis, utrinque 

 pilis longis, albis, simplicibus, interdum apice brevissime furcatis, 

 copiose vestitis ; scapo tenui subglabro, superne, cum involucri foli- 

 olis exterioribus lineari-acuminatis, demum recurvis, pube brevis- 

 sima stellata, pilis raris intermixta, parcius adsperso ; achenii sub- 

 erostris costis vix rugulosis. 



Hab. in saxosis Galiise australis, Pedemontii et (?) agri Forojuliensis, 

 infrequens. Habeo e Gallia prope Gap, comm. el. Jordan ; atque 

 ex Pedemontio juxta Col di Tenda, ubi detexit el. Renter. 



Syn. L. hirtum, Vill., et forsan Linn. sp. 1 123. Apargia Villarsii, W. 

 Pio-is hirta, All. 



This species, very distinct in appearance from the preceding 

 members of this section of the genus, is closely allied to the fol- 

 lowing species, of which it might be considered a subspecies -f E 

 but for the diflferences found in the hairs and fruit of L. Rosani. 



9. X. Rosani, D.C. Prod. Radice subfusiformi, obliqua, parce fibrosa ; 

 foliis oblongis, profunde pinnatifidis, segmentis spathulatis oblon- 

 gisve, anguiatis, e pilis longis albis, sub lente asperis, interdum sim- 

 plicibus, sfepius apice bifurcatis, vitrinque birtis ; scapo tenui sub- 

 glabro, superne, cum involucri foliolis lineari-oblongis adpressis, 

 pube brevissima stellata, pilis raris intermixta, adsperso ; achenii 

 vix rostrati, costis eminentibus muricatis. 



Hab. in apricis Italise mediae et inferioris baud infrequens. Legi in 



* I possess a specimen of the common L. hastilis A, gathered at the 

 same time on this mountain.
