Mr. J. Ball on the genus Leontodon. 7 



I possess specimens gathered by myself in the Eastern Pyre- 

 nees ( Val de Carol), and on Brandon Mountain in Kerry, which, 

 from the peculiarity of their habit rather than from positive cha- 

 racters, I was disposed to consider distinct ; neither of the speci- 

 mens were in fruit, and for the present I am inclined to refer 

 them to a form of L. autumnalis, which I would distinguish as a 

 variety of the subspecies joc/i/s^m — e. 



Sect. II. Apargia. Radix prsemorsa. Foliola involucri interiora 

 biseriata subaequalia ; exteriora brevia. Pappi radii insequales, inte- 

 riores plumosi, ad basin dilatati, serrulati ; exteriores breves, scabri. 

 Pili simplices, seu furcati. Achenia suberostria. 



2. L. Taraxaci, ho\s. Radice praemorsa, fibris validis prsedita ; scapo 

 simplici, superne sensim incrassato, subsquamoso ; foliis lanceolatis» 

 in petiolum attenuatis, subintegerrimis, vel lobato-dentatis, vel in- 

 terdum insequaliter pinnatifidis, lobis latis triangularibus ; involucro 

 laxo, fusco-villoso, pappo niveo. 



Hab. in pascuis alpinis Gallise, Helvetise, Germanise, et Italise supe- 



rioris. 

 Syn. Apargia Taraxaci, W. Hedypnois Taraxaci, Vill. 



This very distinct species appears to be confined to the Alps 

 of Central Europe; I suspect that the Carpathian habitat re- 

 corded by Beichenbach should be referred to the following spe- 

 cies. In both the flowering stem is shorter than in the allied 

 species. 



3. L. erocew*, Rcbb. (anHke.). Scape simplici, superne aliquantum 

 incrassato, subsquamoso ; foliis lanceolatis, grosse et insequaliter 

 pinnatifido-dentatis, lobis triangularibus, integris ; involucro piloso ; 

 pappo sordide albo. Herba tota subglaberrima. 



Hab. in alpibus Austriacis et in Carpathis septentrionalibus. (Legi 

 prope Zakopana, et in jugo alpino supra Biala Thai in Carpatho- 

 rum montibus Tatra. Habui ex iisdem montibus sub nomine L. 

 Taraxaci comm. Dr. Gerenday.) 



Syn. Apargia crocea, Willd. ? 



I do not feel quite certain as to the synonymy of this species, 

 the descriptions of the authors cited being incomplete. The 

 Carpathian plant is intermediate between L. Taraxaci and L.py- 

 renaicus, but it is nearer to the former ; the colour of the pappus 

 aflfords a satisfactory character by which it may be distinguished. 



4. L. pyrenaicus, Gouan. Radice prsemorsa, undique fibrosa; scapo 

 monocephalo, squamoso, superne sensim incrassato, ante anthesin 

 nutante ; foliis spathulato-lanceolatis, obtusis, versus basin repando- 

 denticulatis, glabris vel pilis simplicibus adspersis ; acheniis utrin- 

 que attenuatis vix rostratis, costis vix rugulosis. 



A. alpinus, involucro fere glabro, scapo superne incrassato. 

 Hab. in pascuis alpinis Europee mcdire, frequens.
