APPENDIX 



SUPPLEMENTARY LITERATURE 



The following references are inserted in order to enable any who so desire to 

 obtain more detailed information concerning the subjects treated in Part III. A 

 complete bibliography is quite out of place, but it is hoped that the most useful 

 references may be found in the appended list. In all cases the references chosen 

 are those which generally will be found relatively accessible in libraries containing 

 the leading botanical and biological journals. No attempt is made to give the 

 older references, chief attention being paid to those of recent date, in which allu- 

 sion to older treatises may generally be found. 



Following each topic is the page of Part III to which reference is made, as (491)- 

 The authors to whom no reference is made other than by name are those men- 

 tioned in the General List, as HABERLANDT and GOEBEL I. The arrangement 

 of authors under each topic is alphabetical, and the abbreviations of the various 

 journals will be intelligible to any librarian or to any one acquainted with botanical 

 and biological journals.
