of physiological responses belongs the rapid development of 

 flowers in the case of azaleas and the like, which have been sul> 

 jected to the action of an anaesthetic such as ether. It may 

 be that the similarity of response to these apparently different 

 conditions is due to a real similarity in the conditions them- 

 selves for low tcunx'ralin-c, tliorough drvinji: out, and tlie action 

 of an anaesthetic all act upon the ]ilant to bring about almost 

 a complete cessation of the various life processes, and this en- 

 forced period of rest may possibly bring about the unseasonable 

 flowering. — B E. L. 



DISEASE OF SYCAMOEE TREES. 



lu the issue of Plant World of September, 1907. there 

 app(^<ii'('d an inquiry from !Miss Broadhurst concerning the dis- 

 eased condition of sycamore trees in the Eastern States. The 

 disease referred to was explained by Lloyd as due to the fungus 

 receutlv described bv Murrill. 



] )uring the past summer, the undersigned made a personal 

 examination of these diseased sycamore trees and found that 

 this condition was not due to a fungus but to late spring frosts. 

 On none of the branches did any fungus occur, but all the ap-

 report of tlic Missouri Botanical Garden. — Hermauu von
