PLANTS OF SOUTHERN NEW JERSEY. 597 



Camden County, and recently Mr. Bayard Long collected it at 

 Fish House.

DERINGA Adanson.* 

 Deringa canadensis L. Honewort. 



Sison canadensis Linnseus, Sp. PI. 252. 1753 [Virginia]. 

 Cryptotcania canadensis Willis 26. — Britton 115.

 the upper Middle district.

SIUM L. 



Sium cicutaefolium Gm. Hemlock Water Parsnip. 



Sium cicutccfolitim Gmelin, Syst. II. 482. 1791 [Siberia]. — Britton 114. — 



Keller and Brown 241. 

 Sium latifolium Barton, Fl. Phila. I. 141. 1818. 

 Sium lineare Barton, Fl. Phila. I. 141. 1818. — Willis 26. 



Frequent in swamps of the northern counties and coastal strip, 

 and along the Delaware in West Jersey. 



This species and Oxypolis rigidior are frequent associates of 

 Cicuta macidata, but are neither of them so generally distributed. 

 The present plant seems to prefer larger, wetter swamps, and is, 

 I think, most abundant along the coast. 



Fl. — Mid-July to late September. Fr. — Late August through 

 October. 



Middle District. — Monmouth Co. (Willis), BurHngton, Delair, Kaighns 

 Ft, Mickleton (KB), Swedesboro, Salem (S), Bridgeport (KB). 



Coast Strip. — Long Branch, Forked River (CDL), Bay Head, Barnegat 

 City (L). Surf City (L), West Creek, Crowleytown, Absecon (S), Ocean 

 City, Piermont (S), Anglesea, Wildwood, Tuckahoe (S), Cold Spring, 

 Court House. 



* Tanidia integerrima (L). Yellow Pimpernel. Smyrnium integerrimum 

 Linnaeus, Sp. PI. 263. 1753 [Virginia]. Frequent in rocky places in the 

 northern counties, but its occurrence within our limits rests entirely upon 

 Knieskern's statement that it is found rarely on shady banks and in open 

 woods in Monmouth and Ocean Counties. We have been unable to verify this 

 statement.
