mens bearing old fruiting inflorescences, and in no instance do 

 they appear to have been destroyed by disease or fire. Other 

 observers who have had the opportunity to study them during 

 their entire stage of reproduction, assert that the plants show 

 signs of decay with the maturing of their fruits and soon after- 

 ward die. It would undoubtedly afford an interesting subject 

 for investigation to ascertain the age the various species of 

 Spathelia reach before producing their flowers and fruits. Defi- 

 nite information upon this subject appears to be lacking.

Alexander's Outline K y of nichigan Sunflowers* 



The utter impossibility of fitting the sunflowers of south- 

 eastern Michigan into the specific limits of sunflowers as given 

 in the manuals, has led Mr. Alexander, of Detroit, to undertake 

 the study of these plants. As the result of six years of study, he 

 has worked out a system of classification of the perennial sun- 

 flowers, based upon the underground parts of the plants. He 

 recognizes two main groups which he calls the Storeatae, in 

 which the roots and root-stocks are tangled together into a close
