being the only species of this division reaching as far west as Italy. 

 The orange species all occur east of the Adriatic. The genus is 

 remarkable for the wide ranging in altitude of the majority of 

 species, those that are essentially alpine or lowland being com- 

 paratively few in number. The islands of the Mediterranean afford 

 many conspicuous examples of the geographical isolation of indi- 

 vidual species. The Balearic Islands, Corsica, Syra, and Cyprus, 

 each have their special species, and there are also many cases of 

 insular variations of s^Decies found on the adjacent mainlands. 



The author also referred to many curious cases of subordinate 

 secondary characters common to species geographically associated, 

 and, in conclusion, referred to the tendency of nearly every part of 

 a Crocus to morphosis ; notably to the stigmatic appendage to the 

 anther, to the conversion of the membranous spathes into proper 

 leaves, and to the development of the perianth segments into 

 stigmata, and spoke of Mons. Chappillier's experiments on an 

 abnormal form of C. sativus, m which the segments are converted 

 into an extra whorl of stigmata, or saffron.
