This is not an Italian species, as frequently stated. The 

 original locality given by Balbis is, " sur les bords des champs 

 dans les montagnes de Tende," which is in the area ceded with 

 Nice to Prance in 1860. Neither is it the D. tener of the ' Flore 

 de France, 1 which = D. fallens, Timb. Heichenbach refers the 

 plant to D. Waldsteinii, and Bertoloni, who examined Balbis's 

 original specimens, was of the same opinion. On the other hand, 

 "W. D. J. Koch referred it to D. neglectus, to which it is similar 

 in many points, but the latter is certainly not a fimbriate species. 

 The plant was raised from seeds from the original locality, in 

 the Jardin des Plantes, and showed no variation in the course of 

 ten years.
