the Hudson to the junction of the Harlem. 

 N. J. NearWoodbridge, Middlesex Co. and Absecon, Atlantic Co. 



Rare and local along our coastal marsh-lands ; apparently reaching

3. P. aviculare L. {P. monspeliense Pers.). A weed in cultivated 



and waste grounds: nearly throughout N. Am. 

 Abundant as a weed throughout the area. 



4. P. neglectum Besser. A cosmopolitan weed found throughout 



the N. Temp. Regions. 

 Common everywhere. 



5. P. buxiforme Small (P. littorale Auct. not of Link). On 



shores and in waste places: N. B. to Minn, and Cal., south 

 to Va., 111. and Kan. 



Occasional in our range, the known stations lying between 

 Stonington, Conn, and Woodbridge, N. J. These and the inter- 

 mediate stations are all near tidal marshes. 



6. P. prolificum (Small) Robinson. (P. ramosissimum prolificum 



Small). In saline soil: Minn, to the N. W. Terr., N. Mex. 

 and Cal., and on the Atlantic Coast from Me. to N. J.

 Litchfield, Conn. 



7. P. atlanticum (Robinson) Bicknell. In salt marshes: Me. to 



N.J. 



Scattered through the coastal marshes. 



8. P. erectum L. In moist or dry soil: Me. to Ont., the N. W.

 in the pine-barrens of L. I. and N. J. than elsewhere.

The reported occurrence of P. Rayi Babingt. in the range, is an error. P. provinciale 

 C. Koch, has been found as a waif, and P. ramosissimum Michx. has been collected as a 



roadside waif in Conn.
