 and Florida, extending northward through the Eastern States as 



far as Vermont. This theory of distribution seems to be strength- 

 ened by the fact that the species of each section are, in general,

 " Floral Structure of Chrysanthemum cinerariifolmm, and other 

 species of Insect Flowers." He introduced his notes by remarks 

 on the increasing importance of the study of Vegetable Histol- 

 ogy, which in its practical bearings might be called " Applied 

 Vegetable Anatomy." As the most important diagnostic char-

he 



mentioned and described the peculiar horizontal trichomes on the 

 involucral scales. He spoke of sclerenchyma forming a large 

 portion of the scales, the collenchyma in the stems and the sto- 

 mata on the ligulate corollas. Some differences between these 

 true " insect flowers" and adulterants were pointed out.
