The accompanying figure was prepared from a specimen in the Berlin 

 Herbarium, which if not actually the type is doubtless the species de- 

 scribed under the above name. I have not seen any specimen in any 

 other herbarium which I could refer without doubt to this species ; 

 but a longer series of specimens would be necessary, to enable one to 

 form a correct judgment as to the amount of variation exhibited by 

 this and allied species. I am indebted to Dr. Engler, the Director of 

 the Berlin Botanic Garden, for the loan of the specimens of the Mexican 

 Eryngia contained in the herbarium attached thereto. Like the other 

 herbaria that I have seen, it contains several forms not met with 

 elsewhere. — \V. Botting Hemsley.
