HARVARD BOTANICAL MEMOIRS 



Under the bead of Harvard Botanical Memoirs it is 

 proposed to include all quarto publications issuing from 

 the Gray Herbarium, the Cryptogamic Herbarium, and 

 the Botanical Laboratories of Harvard University, in- 

 cluding theses presented for the degrees of I'h.D. and 

 S.D. in Botany. Inasmuch as some of the future 

 publications are likely to be continuations of subjects 

 treated in quarto papers already published, it seemed 

 desirable to begin the numbering of the Memoirs with 

 the year 1SS0, the date of the first quarto publication 

 of any member of the botanical staff at present con- 

 nected with Harvard University.
