The coastal plain representative of the usually more northern var. 

 Pylaei (Laharpe) Fernald & Wiegand, the latter plant having usually 

 strongly costulate culms, but larger flowers (3-4.3 mm. long), with 

 the sepals definitely exceeding the petals. In the Cape Cod region 

 var. COftvlatut is the most abundant variety of ./- efftUW and in a 

 letter concerning its occurrence in New Jersey Mr. E. B. Bartram 

 wrote, under date of November 9, 1914: "When I first collected the 

 New Jersey plant in June I was strongly impressed with the appear- 

 ance it made in the field as compared with var. Holtthts. The two 

 plants wen' common in the same marsh but they formed large col- 

 onies that could readily be distinguished from each other at a con- 

 siderable distance. The darker colored and more compact inflores- 

 cences of the unnamed variety contrasted strongly with the lighter 

 colored and more open inflorescences of var. toluttu. In travelling 

 to and from New York across the northern portion of the New Jersey 

 coastal plain 1 was able to distinguish the two forms quite clearly 

 from the train. From these observations 1 should say that the var. 

 ftolutus is decidedly in the minority throughout the region between 

 Trenton and New Brunswick. . . . We turned up the same 

 thing in lower Delaware along the Indian River." See p. 145.
