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 Ai^argia hispanica, W. 



16. L. adhcBrens, Fzl. Radice fusiformi ; foliis oblongo-lanceolatis, 

 subintegerrimis aut iuterdum sinuato-dentatis, utrinque, cum scapo 

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

 foliolis quadrifariam imbricatis, lanceolatls, acuminatis ; achemo 

 breviter rostrato, parum ruguloso (in spec, immaturis) ; iudumento 

 totius plantse variae lougitudinis e pilis sat longis, brevioribus, et 

 subsessilibus intermixtis.

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. i.as/)er/*mM«,BoissMSS. Radice fusifonni; foliis oblongis,lobato- 

 deutatis, cum scapo striate, squamuloso, basi folio unico iustructo, 

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

 brevissime stellatis, undique strigosis ; involucri cylindracei foliolis 

 quinquefariam imbricatis sequidistautibus, exterioribus lanceolatis, 

 acutiusculis, mavgine et dorso pilis brevibus rigidis ciliatis, inte- 

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

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

 mosis, triseriatis, insequalibus ; receptaculo fimbrillifero.

This very distinct species greatly 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 nearly 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.
