434 Macfarlane on Sarracenia Catesbaei. 



mens collected by L. F. Ward, near Florence, were in bloom 

 on April 17th. The next species to flower is S. iiava, which 

 is a week to ten days later at corresponding localities; suc- 

 ceeding it is 6". variolaris, still later 6". psittacina and pur- 

 purea, while 5". rubra and 5'. DruuDiwndn bloom from three 

 weeks to a month later than does 5. Catesbaei. 



Though other diagnostic points were wanting, the odor of 

 blooms of 5. Catesbaei and 5. flava suggest decided differ- 

 ences. As has been observed by Torrey those of the latter 

 are heavy, disagreeable and suggestive of a compound of 

 Catnip and Turkey Rhubarb ; this, moreover, is specially 

 strong in an April evening from 7 till 10. The odor from 

 the former suggests a delicate lemon-violet combination. It 

 would be instructive to know what insects frequent these 

 blooms habitually in dififerent localities, for while the writer 

 has gathered some statistics, they are fragmentary and should 

 be widely supplemented. 



Special acknowledgments for generous help are due to Dr. 

 Sledge and his friend Mr. H. G. Gayfer, of Mobile, who 

 have in every way exerted themselves to secure material and 

 information, and who kindly introduced the writer to native 

 localities for the species. I desire also to thank the Directors 

 and Curators of the Botanic Gardens and Herbaria above 

 mentioned for courtesies extended.
