Preface — To Teachers. 5 



It has not seemed best, however, to follow the plan there em- 

 ployed of capitalizing certain specific names. The simpler, and I 

 think the proper method — that now followed by very many if not 

 most leading botanists — of entire decapitalization, has been fol- 

 lowed. 



To avoid the possibility of any confusion when reference to or 

 comparison with the names as given in Gray's Revised Manual 

 (6th edition) is made, the necessary synonyms are given in paren- 

 theses. 



The "Catalogue of Ohio Plants" by Kellerman and Werner, pub- 

 lished in the Geology of Ohio, Vol. VII, part II, pp. 56-406, has 

 been followed in selecting the species that are given in the follow- 

 ing pages. 



This Flor.v is not designed to accompany any particular text- 

 book on botany. It can be used equally well in connection with 

 anv one of the numerous botanical text-books found in the various 

 schools throughout the State. 



It is suggested, however, that instead of the ordinary plan of 

 text-book use, either the laboratory method be employed (in which 

 case Spaldhigls "Introduction to Botany;" or Arthur, Barnes and 

 Coulter's "Plant Dissection" could be advantageously used); or the 

 instruction be giyen orally by the Teacher. The main points in the 

 structure, organography and physiology of plants could be given if 

 such a plan were followed. Blackboard outlines, figures and illus- 

 trative specimens should be efficient aids. The work could be 

 properly adjusted to the ability and needs of each member of the 

 class. The study could be a real study of the plants, their organs, 

 functions, etc., to the exclusion of redundant terminology. The 

 only book required on the part of the pupils would be this Flora, 

 by which they could identify the native plants. The Teacher could 

 use for the selection and arrangement of the topics, an}- one of the 

 more comprehensive text-books, as Bessey's " Essentials of Botany," 

 Bastin's "Elements of Botany," Vine's "Student's Text-book," Beli- 

 ren's "Text-book of General Botany," Kellerman's "Elements of 

 Botau}-," Gray's botanical works, etc. 



Any suggestions from the teachers of the State in reference to 

 an improved edition will be most thankfully received.
