 Fish House.

 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 axe frequent associates of 

 Cicuta maculata, 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.

*T(znidia integerrima (L). Yellow Pimpernel. Smyrnium integerrimum 

 Linnaus, 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 



1 Counties. We have been unable to verify this
