KANSAS ACADEMY OF SCIENCE. 



They are found in all climates, in all soils, and at all altitudes. It Is thought, there- 

 fore, that the conclusions reached in regard to Compositae will be fairly applicable to 

 the whole flora of Kansas, and what is true of Kansas in this respect is probably 

 equally true of the plains to the south and north for several hundred miles. 



The 62 genera which I know to be represented in Kansas have been arranged in 

 the table given below. In column 1, are the genera; in column 2, are checked those 

 which occur in Mexico; in column 3, those which occur in the region east of the 

 Mississippi river and north of Kentucky and Virginia; in column 4, those found in 

 our southern flora, from the above region to the Gulf; in column 5, those occurring in 

 the Rocky Mountains; in column 6, those found in Mexico and throughout the 

 United States; in column 7, those found on the plains, and would include those 

 which are not confined to the eastern fourth of the State 



The four genera marked (^) are introduced. These, together with the following 

 11 genera, which are found widely distributed throughout the United States and into 

 Mexico, or even as far south as Chili, can be disregarded in the present discussion: 

 Eupatorium, Chrysopsis, Solidago, Aster, Erigeron, Ambrosia, Helianthus, Arte- 

 misia, Senecio, Cnicus, and Gnaphalium. At least two of these, Artemisia and Gna- 

 phalium, are probably southern extensions of northern forms. 



The following are Rocky Mountain genera, not extending east of the plains: 

 Townsendia, Franseria, Bahia, Actinella, Lygodesmia, and Troiimon. Three of 

 these also extend into Mexico. 



Five genera, marked (-) in the list, are of wide northern distribution, and extend 

 southward along the mountains or through eastern United States: Anteuuaria, 

 Achillea, Hieracium, Prenanthes, and Taraxacum. 



There is no genus common to Kansas and the northeast region which is not also 

 found in the southeast region.
