PREFACE. 



The work which forms the basis of this catalogue of Michigan plants 

 is a "Catalogue of the Phsenogamous and Vascular Cryptogamous Plants 

 of Michigan, Indigenous, Naturalized and Adventive, by Charles F. 

 Wheeler and Erwin F. Smith," which was published in the tenth annual 

 report of the State Horticultural Society, 1880. Some years siuce E. F. 

 Smith was appointed by the Department of Agriculture a special agent to 

 investigate the Peach Yellows. The loss of Dr. Smith's assistance in the 

 preparation of this revision is deeply regretted. Much new matter is 

 added in the introduction which, it is hoped, will make the work useful to 

 agriculturists, horticulturists, and all persons interested in floriculture, 

 forestry, etc. The catalogue proper has been revised and corrected as far 

 as possible. With few exceptions, the sixth edition of Gray's Manual has 

 been followed in the arrangement of orders and genera, and in nomenclat- 

 ure. We do not thereby wholly indorse the conservatism of that excellent 

 work, but as this catalogue is prepared mainly for the use of those persons 

 to whom Gray's Botany is perhaps the only accessible book on the subject, 

 we feel justified in using it as a basis of nomenclature. 



A large majority of the plants admitted to this list have been collected 

 by the compilers in different parts of the State- during the past twenty-five 

 years and, with very few exceptions, the name of no plant is published of 

 which there is not an authentic specimen in some herbarium, public or 

 private. 



A large number of species of mosses, liverworts, saprophytic and para- 

 sitic fungi have been collected, a separate catalogue of which may be 

 published in the future. Any one finding plants which are not in this 

 list, or new stations for rare plants, should send us notice of the locality, 

 with specimens, if possible. 



It is hoped that the publication of this list will stimulate local observers 

 and collectors in all parts of the State to assist in contributing to the
