THE AMERICAN BOTANIST 49 



Among those who have recently felt the charm of the 

 "Great Silences" is the Editor of the American Botanist. 

 Called to Arizona on other business in 1919, the ruling pas- 

 sion, — his love for flowers and the vast blue-canopied out-of- 

 doors, — drove him afield for some days in July and August. 

 He chose as his field of exploration the Navajo Indian Reser- 

 vation, particularly Navajo Mountain and its environs 



Actuated merely by his love of the work and with no 

 thought of exploration for novelties, he made his collections 

 with thoroughness so far as the particular area covered is con- 

 cerned. At the close of the season it was my good fortune to 

 have the more than one hundred and fifty numbers submitted 

 to me for examination, and it thus transpires that I have had 

 the pleasure of studying these collections with Mr. Clute. This 

 paper is in the nature of a report to him and carries the sug- 

 gestion that the results of his w^ork be made of permanent 

 record in the American Botanist. 



The comments following the list of species are from Mr. 

 Clute's excellent notes.
