TJie Occurrence of TracJielhun cceruleuin. g 



Algeria contains only T. ccum/eum, where it is very 

 abundant. 



Eight species of this genus, therefore, exist in all, 

 members of the Mediterranean region, either E. or W., 

 but, as already observed, no one species extending through- 

 out the entire area. 



Specimens of T. cccrukiim (L.) are in either Mr. Charles 

 Bailey's herbarium, or mine, or both, from the following 

 localities. And here I must take the opportunity of sincerely 

 thanking Mr. Bailey for the copious notes and quotations 

 that accompanied his list as given below.
