genetical race which takes the place of typical S. graminea in the 

 region of the pine-barrens. Because of its geographical and eco- 

 logical homogeneity, it now seems best to consider this population 

 as a subspecies. Collections from along the Delaware River and 

 from southern New Jersey outside the pine-barrens represent the 

 typical race. Only a few specimens from these places are interme- 

 diate in character. 



Collections additional to those cited with the original descrip- 

 tion of S. Edivardsiana are now listed. Atlantic Co. : Pleasant Mills, 

 near mouth of Hammonton Creek, Bayard Long 4658 (Ph). Bur- 

 lington Co.: Wading River, W. H. Leggett (NY) ; swift flowing 

 water, Batsto River n. n. w. of Quaker Bridge, Bayard Long 7736 

 (Ph), also 7743 (Ph) ; 6^. W . Conrad (Ph). Gloucester Co.: Wil- 

 low Grove near Newfield, C. A. Gross (Ph). 



Intermediate specimens have been seen from two counties 

 in New Jersey and from one in Pennsylvania. Burlington Co.: 

 Delanco, Bayard Long (Ph) and H. B. Meredith (Ph). Camden 

 Co.: Camden, T. F. Seal (Ph). Bucks Co.: Mud Island, Anda- 

 lusia, C. S. Williamson (Ph). 



/ Anacharis canadensis (Michx.) Planchon. Although Taylor 

 (1915) reported that he had seen no specimens of this species from 

 our range, the writer has collected it or examined material from 

 Middlesex, Morris, Passaic, and Warren Counties, also doubtful 

 material from elsewhere. 



/ Panicum spretum Schult. Passaic Co. : Clifton, field east of 

 River Drive at Delawanna, W . Marold and C 1221 (BH, Corn). 

 The northernmost previous collection of this species in New Jersey 

 was from Shark River Station, Monmouth Co., M (NY). 



Carex incomperta Bickn. Although cited from only Burling- 

 ton, Morris, Passaic, and Union Counties by Taylor (1915) the 

 writer has now seen or collected specimens in Camden, Cape May, 

 Gloucester, Hunterdon, Alercer, Monmouth, Ocean, Salem, and 

 Warren Counties. 



Carex brunnescens (Pers.) Poir. Morris Co.: Budd Lake, 

 W. D. Miller 509 & 510 (NY). Passaic Co. : moist woods in All-
