PLANTS OF NORTH ELBA 7 1 



the family grouping and the consecutive arrangement of the last edition 

 of Gray's Manual have been adopted, but the names of the species are 

 those of Britton and Brown's Illustrated flora. When the name of a 

 species is not the same in both works the name used in the Manual is 

 given as a synonym. This will facilitate the use of the list by those who 

 still follow the Majiual. In this part of the list a synoptical table has 

 been given in "those genera which are represented by five or more species. 

 The names and arrangement of the mosses are as far as possible those of 

 the Manual of North American mosses by Lesquereux and James. In like 

 manner Underwood's exposition of the liverworts in the last edition of 

 Gray's Matiual has been followed. The names and arrangement of the 

 lichens are those of Tuckerman's North American lichens and Saccardo's 

 Sylloge fungorum has chiefly been followed in the list of fungi. The fresh 

 water algae have not been sufficiently collected or studied to warrant 

 their introduction. 



It is very evident that this list is far from being complete. A large 

 area of mountainous forest lying between Lake Placid and McKenzie 

 pond has not been explored. The same is true of considerable tracts in 

 the eastern and southeastern parts of the town. Another unexplored 

 region surrounds and includes Mt Street, and a large tract in the western 

 and southwestern part has probably never been visited by any botanist 

 for botanical investigation. It is not unreasonable to suppose that these 

 regions will furnish some additions to the list of flowering plants, ferns 

 and mosses, but it is very evident that many additions may yet be made 

 to the hst of fungi, not only from these places, but also by a more 

 extended and careful search in places that have already been visited. 

 Unhsted species may specially be expected among the Hypodermeae, 

 Pyrenomyceteae, Discomyceteae, Hyphomyceteae, Sphaeropsideae and 

 Myxomyceteae. 



Many plants not included in the list are known to occur in places just 

 beyond but close to the town limits. It is very probable that some of 

 these will spread from their present stations into the town and become a 

 part of its flora. I shall be glad to learn of any additions to the North 

 Elba flora that botanists may make and of the localities where such 

 additions may be found. 



. I desire to acknowledge most gratefully the aid I have received from 

 specialists in the preparation of this hst of plants. Mrs E. G. Britton, a 

 most excellent and enthusiastic bryologist, has very kindly communi- 

 cated to me the results of her extensive observation and study 

 of the mosses and liverworts of the region, and has most generously 

 permitted me to make free use of her descriptive and critical notes on 

 the species. She has added many species to the list of the Bryophyta
