REPORTS ON THE FLORA OF THE BOSTON 
DIS'TRICT.— III. 
IN preparing this list of the Liliaceae it has seemed best to the 
Committee to omit several introduced species that are mentioned in 
some of our local floras. In most cases this is because no records of 
existing specimens have been received, while the few definite records 
that do exist, indicate that such plants are merely persistent and not 
spreading. 
The plants introduced around Concord by the late Minot Pratt 
have thus been purposely omitted. In fact, only one herbarium 
specimen of the Liliaceae has been reported, and that plant, Trillium 
grandiflorum Salisb., is gradually losing ground. Persons interested 
are referred to the lists published by the late Alfred W. Hosmer, in 
Ruopora i, September, 1899. These records of nine years ago, 
without recent reports, do not seem to the Committee sufficient to 
entitle any of these species to a place here.
