Mr. J. Ball on the yenus Leontodou. 



f 



I possess specimens gathered by myself in the Eastern Pyi'e- 

 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 j»«/w5/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, Lois. Radice prsemorsa, fibris validis praedita ; scapa 

 simplici, superne sensira incrassato, subsquamoso ; foliis lanceolatis, 

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

 terdum inaequaliter pinnatifidis, lobis latis triangularibus ; involucre 

 laxo, fusco-villoso, pappo niveo. 



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



rioris. 

 Syn. Apargia Taraxaci, W. Iledypnois 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 Reichenbach should be referred to the following spe- 

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

 species. 



3. L. croceus, Rcbh. (anHke.). Scapo simplici, superne aliquantum 

 incrassato, subsquamoso ; foliis lanceolatis, grosse et inaequaliter 

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

 pappo sordide albo. Herba tota subglaberrima. 



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

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

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

 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- 

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

 affords a satisfactory character by which it may be distinguished. 



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

 moiiocephalo, squamoso, superne sensim incrassato, ante anthesiii 

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

 dcnticulatis, glabris vel pilis simplicibus adspersis ; acheniis utrin- 

 que attenuatis vix rostratis, eostis vix rugulosis. 



A. alpinus, involucre fere glabre, scape superne incrassato. 

 Hab. in pascuis alpinis Eurepoe medice, frequens.
