PREFACE. 



All thei-- localities have been credited as far as could be 

 ascertained with accuracy. In McMurtrie's History of 

 Louisville, he gives Scolopendrium officinarum (Swartz), 

 as found near Louisville, Ky. This is certainly doubtful. 



The present work is not so full in localities as it ought 

 to be, and it is the earnest desire of the author that local 

 collectors should communicate with him regarding this 

 matter, noting carefully the time and the place of finding 

 any plant described in these pages— whether on the higher 

 ranges; whether on the declivities, or in the valleys, in the 

 .damp, rich woods, or along the banks of streams; whether 

 on trees, or overhanging rocks; whether the rocks are 

 ■sandstone, limestone, or of igneous formation. Notes 

 can not be too careful or minute. 



This is merely a beginning of what can be accomplished 

 with the aid of local collectors. We hope in a litde time 

 to be able to determine the locality and range of every 

 species and variety indigenous to the State. 



I now take this opportunity to thank my botanical friends 

 for the kind assistance they have given me in this work- 

 Mr. J. C. Martindale, of Camden, New Jersey, Mr. John 

 H. Redfield, of Philadelphia, Prof. D. C. Eaton, of Yale 

 College, Prof. Coulter, of Hanover College, Indiana, Prof. 

 Hussey, of Purdue University, Lafayette, Ind., Mr. Chas. 

 E. Faxon, and Mr. G. E. Davenport, of Boston. I am 

 especially indebted to Mr. Davenport for his valuable hints 

 regarding the nomenclature and for criticisms on the illus- 

 trations.
