8 Mr. J. Ball on the genus Leontodon. 



Syn. L. squamosum, Lam. Apargia alpina, Willd. {L. alpinum, 

 Jcq. sequent! referendum monente eel. Koch.) 



+ E, — g. subsp. aurantiacus, involucro pube brevi farinoso ad- 

 sperso ; scapo minus incrassato ; ligulis aurantiacis. 



Hab. in alpibus Carinthise et in Apenninorum jugo. (Legi prope 

 Heiligenblut, Carinthise, et supra montera Corno alia Scala in 

 Apennino Bononiensi.) 



Syn. L. aurantiacus. Ten. (an Rcbh.). Apargia aurantiaca, Kit. ? 



This species and the glabrous forms of the succeeding one 

 sometimes much resemble each other, especially before the for- 

 mation of ripe fruit, but the characters assigned, especially the 

 form of the leaf and the disposition of the denticulations towards 

 the base of the leaf, will generally suffice to distinguish the pre- 

 sent species. 



I have not verified the character pointed out by Koch, in the 

 narrow base of the rays of the pappus. 



5. L. hastilis, L. Radice prsemorsa, undique fibrosa ; scapo mono- 

 cephalo, sub-esquamoso, apice parum incrassato ; foliis oblongo- 

 lanceolatis, plus minusve insequaliter dentatis, dentibus versus basin 

 retrorsis ; pilis bi-trifurcatis ; involucri foliolis oblongo-linearibus ; 

 achenii erostris, costis parum rugulosis. 



A. foliis, scapis, involucrisque hirtis ; foliis profunde dentatis, lobis 



triangularibus angulatis. 

 Hab. in Europa et Asia temperata vulgaris, valde ludibundus ; 



variat. 



-)-d. scapo inferne bifurcato (legi in Monte Righi Helvetise). 



— g. pilis frequentioribus brevioribus incanus, frequens in apricis 

 Europse, prsesertim australioris. 



+ i. foliis acute runcinato-pinnatifidis, lobis dentatis. 

 Syn. L. crispus, Reich, et Thomas, non Vill. 

 Habui ab ipso cl. Reicbenbach, atque iterum ab E. Thomas ad 



Zermatt in Valesia lectum. Ipse legi, in Gallise montibus Ar- 



vernise et Delphinatus, et in Italia superior! juxta Lacum La- 



rium, necnon in convalle Leventina. 

 Adsunt etiam varietates plurimse quae subspecies sequentes appro- 



pinquant. 

 Syn. L. hispidum, L. Hedypnois hispida, Sm. Apargia hispida, 



Hort. Hieracium incanum. Poll. 



-|-G. subsp. danubialis, foliis, scapis, involucrisque glabris, seu 

 pilis raris furcatis nonnunquam etiam simplicibus adspersum. 

 Frequens in montanis et mnbrosis Europse fere totius, sed om- 

 nino desideratur in Anglia et Hibernia ubi species frequentissime 

 occurrit. (Habui etiam ex Persise Monte Elbruz a eel. Kotschy.) 



Syn. L. hastilis ft. gJahratns, Koch. L. hastile, L. L. danubiale,
