My dear Mr . Deane : 



Your letter of May 9th is just at hand. I am glad to learn 

 that the photographs reached you in good condition. The orchid 

 photograph is the one of the Holy Ghost plant about \vhich Mrs. 

 Bose wrote you some tine ago. I suppose you observed the dove 

 in the center of the flower. By the way, Mrs. Rose wished me to 

 ask whether you had received her letter or not. 



I intended to enclose with the photographs a copy of the 

 description of Ro sec cactus which appeared in I'ebruary last, and 

 consequently you were not able to find the name in the cactus 

 book. This simply goes to show how unstable or perhaps incom- 

 plete our botanical knowledge is of any of the great groups of 

 plants. Since the appearance of the monograph three new generic 

 names of cacti have been dedicated to me; Roseo cactus , Berger, 

 of which you have the photographs; the genus Roseia by A. V. 

 Erie of Prague; and Brit t onrosea by Spegazzini of Argentina. It 

 seems to me tt.at I am getting more than my share of generic names. 



Mrs. Rose and I have just received an invitation to the 

 unveiling of Doctor Gray's bust at the Hall of Fame of Kew York 

 University next week. We should both love to go, but doubt 

 '.vhether we can of not. I suppose I owe my invitation to Doctor 

 Robinson who, I see, is to deliver the address. I have also been 

 invited to attend commencement out at Wabash College thiis year 

 and I rather expect now that I shall go out for a few days. 



Yours very truly 



J. Rose

Division of Plants.
