THE GENUS SUAEDA IN NORTHEASTERN AMERICA. 
M. L. FERNALD. 
THE genus Suaeda has long been for the American botanist a source 
of much confusion and difficulty, in part because it consists of unat- 
tractive plants of saline soils which are generally ignored by collectors, 
in part because of the very indefinite conception of the true Suaeda 
maritima of Europe — the species about which our studies, at least 
of the eastern coast forms, must largely center. It has long been 
known to many New England botanists that we have on our north- 
eastern coast more than the single species alloted to this region in 
Gray's Manual; and the two species described and figured (as Dondia) 
in Britton. & Brown's Illustrated Flora satisfactorily cover only the 
forms which occur on the salt marshes and sea beaches from southern 
New England southward. On the coast of Maine are other forms 
which in habit, flowering-season, and fruit-characters are unlike the 
plants of the more southern shores. 
During the summer of 1898 Mr. J. C. Parlin and the writer spent a 
day (July 23) upon Wells Beach and the adjacent marshes in southern 
Maine. At that time a small depressed Suaeda (no. 1) with short 
subeylindric dark green leaves was in mature fruit. Another depressed
