 and Brown 25. 



Locally distributed in ponds and boggy spots in northern New 

 Jersey, southward along the Delaware and in Cape May Co. 

 and the Pine Barrens. 



Most specimens of this arrowhead have well defined lanceolate 

 leaf blades, but in wholly submerged plants, or notably those 

 from tidal mud and gravel on the borders of the Delaware River, 

 the leaf blades are partly or entirely absent, being represented by 

 nearly linear '(or the basal ones lanceolate) phyllodia. The 

 specimens from the tidal mud I have never seen fruiting, but the 

 flowers are much reduced and on very short .pedicels, sometimes 

 nearly sessile. 



Mr. J. G. Smith records a specimen of Sagittaria teres, "N. 

 J. Pine Barrens, Torrey, 1833,"* but in view of the fact that we 

 have no other evidence of the occurrence of this species in 

 southern New Jersey, it seems at least possible that the specimen 

 referred to may have belonged to 5*. graminea.
