But when, in crossing the flat between Schooner Cove and 

 Corbett's Point, Dr. George G. Kennedy drew attention to a little 

 prostrate Glaux, we were greatly interested, for to the others of the 

 party (including Messrs. Emile F. Williams, J. Franklin Collins, and 

 the writer) this form of the plant was equally unfamiliar. The plant 

 at Cutler formed prostrate rosettes rarely a decimeter across, its 

 leaves were narrowly oblong and bluntly pointed, and the flowers 

 were deeply colored throughout, the ordinary white of the calyx-tips 

 being replaced in these plants by a bright lavender. This prostrate 

 plant on the shore of Schooner Cove was well below the high-water 

 mark and during a large part of the day it was completely submerged 

 by sea-water; and since the plant there grew in a very limited area 

 its peculiar habit and deeply colored flowers were thought to be due 

 perhaps to the periodical salt bath it was forced to endure. 



Later, however, on July 24th. Mr. Williams and the writer had the 

 good fortune to find the little prostrate Glaux with the commoner 

 erect New England form occupying many acres of salt-marsh by the 

 Baie des Chaleura near Bathurst, New Brunswick. There the two 

 plants grew under identical conditions, large patches of the taller 

 erect plant occurring side by side with equally extensive areas of its 

 dwarf ally. Both forms were somewhat past flowering and many 

 specimens had fairly mature fruit, and it was found that the plants 

 differed not only in the points already noted at Cutler, but that the 

 fruit of the erect broad-leaved form was larger than in the other. 

 Characteristic material of the two forms from the shore of the Baie 

 des Chaleura was collected, and from a comparison of these and the 

 Cutler plants with the American and Old World specimens in the 

 Gray Herbarium and the herbarium of the New England Botanical 

 Club the following conclusions are drawn. 



The prostrate plant first noted at Cutler and afterwards found in 

 great abundance at Bathurst is not confined in America to the "north 

 shore," but has been collected at two points at least on the Massa- 

 chusetts coast: — Rockport (/. H. Scars) and Somerville {F. S. 

 Collins). This form proves to be the common Glaux maritima of 

 northern Europe and the alkaline districts of interior Asia. But a 

 large number of Old World specimens show that the true (European) 

 Glaux maritima is not always prostrate nor even freely branched, 

 for occasional individuals are subsimple and others have short erect 

 branches. In its narrower pointed leaf and small fruit, however, the
