M. Beguinot donne de nombreux renseignements geographiques 

 et systematiques sur un Diplotaxis (D. versicolor), distribue par MM. 

 Huter, Porta et Rigo dans leur Iter italicum tertium n". 191 et 

 recueilli dans la Calabre sud-orient., qu'on peut considerer comme 

 un des produits de fragmentation d'un type d'aussi large distribution que 

 le D. erucoides L. et qu'on peut rapprocher du D. apula Ten. sans le 

 confondre, dans l'etat actuel de nos connaissances, avec lui ou avec 

 d'autres formes rapprochees. F. Cortesi (Roma).
