PLANTS CULTIVATED FOR THEIR FLOWERS, ETC. 167 



The cultivation of saffron, of which the conditions 

 are given in the Cours cV A gin culture by Gasparin, and 

 in the Bulletin cle la Societe d' Acclimatation for 1870, is 

 becoming more and more rare in Europe and Asia.^ It 

 has sometimes had the effect of naturalizing the species 

 for a few years at least in localities where it appears to 

 be wild.
