238 Bicknell : Studies in Sisyrinchium 



Of these all but S. littorale and 5. Macouni belong also to the 

 United States, though 5. septentrionalc is all but exclusively Brit- 

 ish American. 



Other species known to occur in states adjoining Canadian 



territory are the following : 



.S. Atlanticum Bicknell, Maine (North Berwick, York Co., 

 June 21, 1 89 1, J. C. Parlin, in Herb. Gray, not previously recorded 

 from the state) ; New Hampshire ; Vermont. 



wS\ arenicola Bicknell, Nantucket ; New York. 



kS. Iiastile Bicknell, Michigan. 



*S. Farwellii Bicknell, Michigan.

wS. occidentale Bicknell, North Dakota ; Montana ; Idaho. 



.S'. segetum Bicknell, Washington. 



wS". sarmentosum Suksdorf. Washington. 



Sisyrinchium graminoides Bicknell 



This species is of interest as being the only normally branched 

 species occurring north of the United States. Since it there ex- 

 tends northward to central and western New York and through- 

 out the southern peninsula of Michigan its occurrence in the 

 southwestern extremity of Ontario was to be expected, and it is 

 only surprising that a single specimen alone attests its presence 

 there. Elsewhere in Canada the plant was scarcely to be looked 

 for and it is a matter of no little surprise to find it as far north 

 and east as the coast of Gaspe in Quebec and on Newfoundland 

 and Sable Island. These occurrences afford a most unexpected 

 extension of range as the species appears to be unknown elsewhere 

 in Canada east of Ontario nor in New England beyond eastern 

 Massachusetts. 



The specimens from Ontario and Gaspe are perfectly typical, 

 while those from Newfoundland and Sable Island show depar- 

 tures from the ordinaiy plant so considerable as to give them some 

 rank as insular forms. Indeed the Newfoundland plant would 

 scarcely be taken at all for 5. graminoides and has been distrib- 

 uted as 5. angustifolium Miller (Robinson's & Schrenck's Flora
