EXPERIMENTS IN THE BREEDING OF CERIONS. 



details presented by this material will be discussed at another place 

 in this report. The second plantation on the ridge seemed to have 

 recovered from the effects of the fire, but only a few specimens of the 

 King's Road type were there, and absolutely no trace of an admixture 

 with Cerion incanum was shown in any of the specimens. 



The Colony on Boca Grande Key. 



On June 8, 1912, we planted 500 specimens of Cerion viaregis beneath 

 the U. S. Coast Survey beacon on the northwest end of Boca Grande 

 Key. The ground at this place is the usual coarse-grained calcareous 

 sand supporting a rather luxuriant growth of Uniola paniculata. This 

 colony was doing well on May 1, 1913.
