TAiMARlX GALLICA. 127 



siaii winter, and may have been previously described by the 

 Russian botanists. From its beauty it merits cultivation 

 more than any other species in our temperate zone. 



Having thus far cleared the way, I now proceed to de- 

 scribe the two species into which I divide the T. Gallica of 

 modern botanists. M. Decaisne in his Florida Sinaica, after 

 recording his dissent from the method of uniting so many 

 forms or subspecies under a common type, observes that the 

 disk of T. mannifera, and others which correspond perfectly 

 with the section Decadenia of Professor Ehrenberg, differ 

 entirely from the T. Gallica, and T. Africana, in which " se 

 sont les lobes memes du disque qui vont en s'attenuant, 

 et forment les filets antheriferes." M. Spach shortly after- 

 wards, in his Suite a Bvffon, founded his second section on 

 the T. Gallica and Africana, described as having the disk 

 " non crenele confondu avec la base elargie des filets." 

 The fact is that the plant cultivated at the Jardin des Plantes 

 under the name of T. Gallica, which was studied by both 

 these very accurate observers, came originally without doubt 

 from the western coast, nor did they imagine that two distinct 

 species existed in France under the same name. I followed 

 M. M. Decaisne and Spach in considering in the Phytogra- 

 phia Canariensis, this form as the true T. Gallica, Linn., 

 and on examining the T. Canariensis, I found, on the contrary, 

 that in that species the stamens were inserted in the interval 

 between 5 crenated lobes of the disk, answering to the glati- 

 dula germeii stiffulciens lO-dentafa, Ehrenb., and that in this 

 as in other respects it was identical with T. Senegalensis, DC, 

 and several other forms. Moreover, 1 found from specimens 

 collected by myself in the south of France, that the same 

 plant existed there, and I came to the conclusion that the 

 T. Canariensis was likewise a French plant. Since then I 

 have examined specimens from every part of the French 

 Mediterranean coast, from the Pyrenees to the Alps, and 

 have invariably found them to belong to this plant, and from 

 others brought from various other localities, I am led to 

 believe that this is the sole T. Gallica of the whole Mediter-
