Mr. J. Ball on the genus Leontodon. 15 



larger and more robust in habit than the preceding species ; the 

 involucres are broader, subglobose, and more regularly imbri- 

 cated. It is probably nearly allied to Apargia hispanica, W. 



16. L. adh<erens, Fzl. Radice fusiformi ; foliis oblongo-lanceolatis, 

 subintegerrimis ant interdum sinuato-dentatis, utrinque, cum scapo 

 simplici et involucre, e pilis rigidis stellatis cano-hispidis ; involucri 

 foliolis quadrifariam imbricatis, lanceolatis, acuminatis ; achenio 

 breviter rostrate, parum rugulose (in spec, immaturis) ; indumento 

 totius plantae variae longitudinis e piUs sat lengis, brevieribus, et 

 subsessilibus intermixtis. 



Hab. in Mente Tauro. Habeo specimina Ketschyana e manu clar. 



aucteris. 



This species is easily distinguished by the presence of stellate 

 hairs of various length ; it is much smaller in stature than the 

 last, but the involucre approaches to the succeeding species both 

 in size and structure. 



17. X.ffi«pem'mM«,BeissMSS. Radice fusiformi ; feliisoblongis,lobato- 

 dentatis, cum scapo striate, squamulese, basi folio unico instructo, 

 simplici aut furcate, pilis rigidis, sub lente muricato-asperis, apice 

 brevissime stellatis, undique strigosis ; involucri cylindracei felielis 

 quinquefariam imbricatis sequidistantibus, exterieribus lanceolatis, 

 acutiusculis, margine et dorse pilis brevibus rigidis ciliatis, inte- 

 rioribus lineari-elongatis, ebtusis, glaberrimis, acheniis (in spec, 

 nostris abortivis) rostratis, muricellatis ; (?) pappi radiis longe plu- 

 mesis, triseriatis, inaequalibus ; receptacvile fimbrillifero. 



Hab. in Iberia, Persia, et Asia Minere. Ilabui ex Mente Demawend 

 cemm. cl. Ketschy, ex Caucase erientali a cl. Hehenacker, atque 

 ex Pisidia specimen supracitatum a cl. Heldreich cemmunicatum. 



Syn. Scorzonera asperrinia, Willd. S. hispida, M. B. Apargia stri- 

 gosa, M. B. (Fl. Taur. Cauc.) Asterothrix asperrivia, Cass. 



This very distinct species gi-eatly exceeds in stature, and still 

 more in the size of the floral parts, the preceding species ; it will 

 be seen however that it cannot properly be distinguished gene- 

 rically, being neai'ly connected in essential characters with L. 

 asper and L. adhcerens, while these in their turn can scarcely be 

 separated even as a section of the genus from those which pre- 

 cede them. 



Want of leisure and opportunity having prevented me from 

 comparing my own specimens with those contained in more ex- 

 tensive herbaria, I shall merely quote the descriptions of three 

 species which I have been unable to examine for myself, but which 

 appear properly to belong to the genus ; and I shall further add 

 a list of the uncertain and unknown species which have been 

 attributed to it, though most of the latter are probably either 

 synonyms of the known species, or plants properly belonging to 

 other genera.
