blossoms kept under fairly close observation all but six resulted 

 in nothing but husks. Six, however, produced seed, somewhat 

 resembling that of the common morning glory and these seed 

 were germinated early the following spring, or at least four of 

 them germinated successfully while two did not. The last two 

 seasons we have been on the alert for a recurrence of one of these 

 profuse blossomings, however without result." — L. H. Nelson, 

 Assistant State Horticulturist, North Carolina Experiment 

 Station. 



South Carolina. "Sweet potatoes do bloom quite frequently 

 here and sometimes abundantly, but I have never seen them set 

 seed." — H. M. Barre, Director of Research, Clemson Agricultural 

 College. 



Georgia. "The sweet potato does not generally make seed 

 in this State, but it is reported by growers here and in Alabama 

 that if they are grown in green houses for a long time they will 

 blossom and produce seeds." — H. P. Stuckey, Director, Georgia 

 Experiment Station. 



Florida. "The appearance of blooms on sweet potato plants 

 here is nothing unusual, but it seems that no one has interested 

 himself to follow the matter up and find out if seeds were formed."

 Station. 



During October, 1922, Mr. A. C. Brown, Asst. Quarantine 

 Inspector, State Plant Board of Florida, very kindly sent flowers 

 of several varieties of sweet potatoes to The New York Botanical 

 Garden. Owing to the distance of travel, the flowers arrived in 

 such poor condition that no satisfactory study of the flower 

 parts could be made. 



Alabama. "We have seen only a very few blooms on sweet 

 potatoes in the State of Alabama and I know of no case in which 

 these blooms produced seed." — G. C. Starcher, Horticulturist, 

 Alabama Polytechnic Institute. 



Mississippi. "We very frequently have sweet potato blooms 

 in our fields but it is very seldom that any of the plants have 

 ever set seed. The writer has done considerable work in trying 

 to get seed from the plants but to date no successful work has 

 been done. A few years ago I took cuttings from vines that 

 were blooming and put them in the greenhouse. They kept 

 blooming continually but did not set seed due to their being 

 infertile. There was very little pollen present as was deter- 

 mined under the microscope. 



"H. C. Young of Georgiana, Alabama, has produced a couple 

 of new varieties from seed. He has succeeded in getting three 

 or four of the plants to set seed. I think that it is more a case 

 of lack of pollen than a case of not blooming because several
