A LIST OF THE MOSSES GROWING IN THE STATE 



OF VERMONT 



WITH ANALYTIC KEYS TO THE GENERA AND SPECIES. 



By a. J. Grout, Ph. D. 



INTRODUCTION. 



Very little has been published on the moss flora of Ver- 

 mont since the list of Mr. C. C. Frost in the Archives of 

 Science and Transactions of Orleans County Society of Natural 

 History for 187 1. Some of the plants then listed were un- 

 doubtedly collected outside of Vermont, as is shown by Mr. 

 Frost's labels, and much new information has been gathered 

 since the date of that publication. Unquestionably there are 

 still many species of mosses growing in the State which have 

 not been collected or listed, and it is hoped that this list will 

 aid and stimulate the study of these humble but interesting 

 plants. 



With a few exceptions, which are noted later, no species 

 has been admitted to the list without a careful comparison of 

 Vermont material with descriptions or authentic specimens. 

 Specimens from all of the localities cited, however, have not 

 always been examined. The writer has had access to the col- 

 lections of Mr. C. C. Frost, Mr. C. G. Pringle, Dr. F. Blanchard 

 and to the Columbia University herbarium, which contains 

 duplicates of the Vermont collections of ' Messrs. C. E. and B. 

 Faxon and Mrs. B. G. Britton. Mr. Edwin Faxon has also very 

 kindly sent a list of Vermont localities and many rare specimens 

 from the Faxon herbarium. 



Mr. Frost, in the list referred to above, published a con- 

 siderable number of species which are not included in this list 

 because there are no specimens of the omitted species in his
