Vi MORPHOLOGY OF ANGIOSPERMS 



Any one who has attempted to review the literature of the 

 morphology of Angiosperms will appreciate the great amount 

 of labor it involves, as well as the chaotic condition of termi- 

 nology and citations. There is nothing more baffling than the 

 attempt to follow the guidance of the meager, indefinite, and 

 often incorrect citations of the standard texts. It is believed, 

 therefore, that the attempt to reduce the numerous contribu- 

 tions to a consistent terminology and to make the citations 

 fairly representative of the subject as well as definite and accu- 

 rate will be of some real service to students of morphology. 

 The volume, therefore, seeks to give to the advanced student a 

 continuous account of the structures involved, and to the research 

 student the details of groups and bibliography that he needs. 



In every case where figures have been copied, acknowledg- 

 ment is made and a reference is given to the original paper 

 containing the illustration. It should be noted that much in- 

 formation included in the legends does not appear in the text, 

 so that in any thorough reading of the book the legends should 

 be included. The bibliography pertaining to each subject is 

 printed in chronological order at the end of each chapter con- 

 taining numerous citations. At the close of the volume all of 

 the cited bibliography is brought together, arranged alphabet- 

 ically by authors. 



It would be too large a task to include a complete bibliog- 

 raphy of such a subject, but we have presented what may be 

 regarded as a full representative bibliography, containing, so 

 far as we know, all of the most important contributions. In 

 the very nature of things, some citations may have been 

 omitted that should have been included, but there has been 

 no intentional neglect. 



~No attempt is made to present the details of floral structure, 

 so fully described by the earlier morphologists and taxonomists, 

 since they are easily accessible in numerous texts. Xor have 

 we ventured to enter the old and extensive field of anatomy, 

 although many of its details are pertinent to morphology. In
