594 REPORT OF STATE GEOLOGIST. 



Liliaceae into a series of smaller families of more clearly defined limit- 

 ations. Some changes in prominent genera also occur, but in the main 

 it wiU be found that the present arrangement commends itself to the 

 thoughtful student. 



The sequence of families is that of Britton and Brown, which in the 

 main, follows Engler and Prantl in their great work Natiirliche 

 Pflanzenfamilien. 



In transferring to this nomenclature it is scarcely reasonable to ex- 

 pect that all errors have been avoided. Great care has been given, 

 however, to this part of the work and it is .believed that such errors 

 will only be found exceptionally. 



The catalogue, therefore, stands in the latest authorized form both 

 as to arrangement and nomenclature, and will, it is believed, prove of 

 great service to the botanical students of the State. 



ACKNOWLEDGMENTS. 



In the preparation of this report all published local flora and many 

 manuscript reports have been freely consulted. All data have not been 

 included because of lack of time to study the synonymy of the in- 

 cluded species. The lists coming to my hand were named according 

 to the nomenclature of Wood's Botany, Gray's Manual, fifth edition, 

 Gray's Manual, sixth edition, and the "Blue Book" of the Botanical 

 Club of America. As the present catalogue follows the nomenclature 

 of Britton and Brown's recent manual of the botany of the north- 

 eastern portions of North America, the amount of work involved in 

 the examination of these reports becomes apparent. This will explain 

 the absence of some data which have come to my hand; for the most 

 part, these data bear upon regions covered by other and fuller reports. 

 To all these persons who have furnished me local reports I am under 

 many obligations. In most cases the body of the report gives credit to 

 the proper person, although in some cases where data have come from 

 one person and herbarium specimens from another, credit has been 

 given for the latter. 



For many facts in connection with the part bearing upon poisonous 

 plants, I am indebted to the Report upon Poisonous Plants, published 

 by Mr. V. K. Chestnut, of the United States Department of Agricul- 

 ture, and can only regret that time and space did not permit a fuller 

 use of this valuable publication. 



From the varied publications of Prof. W. S. Blatchley, much ma- 

 terial has been drawn either supplementing data already in hand or 

 in the form of ecologic facts reported from no other source. Mr.
