The day was devoted to studying the flora of the eastern, 

 or New Jersey, side of the Delaware River within the Hmits of 

 Salem County. Particular attention was paid to the relatively 

 high number of maritime species which, although here far from 

 the open sea, occur commonly on the beaches and marshes of 

 this county. 



While waiting for the party to assemble at Pennsville, an 

 unfamiliar Riibus was found growing luxuriantly on the sandy 

 river banks near the wharf. This proved to be R. ulmifolius , a 

 European species doubtless escaped from cultivation and not 

 previously recorded from Salem County. 



The first locality visited was Oakwood Beach, where Lilae- 

 opsis chinensis (L.) Kuntze (Z,. lineata of the Manuals) was seen 

 growing in great profusion and in full flower. Formerly con- 

 sidered rare in southern New Jersey, this curious umbellifer is 

 now known to occur along many miles of the Delaware River 

 shore where it is completely covered by brackish water at high 

 tide. Other maritime plants detected at this station were Spar- 

 tina alternifolia, var. pilosa, Scirpus robustus, Acnida cannabina 

 and Ptilimniiim capillaceum. 



The next stop was at Elsinboro Point, where the party had 

 the good fortune to discover a new locality for Lophotocarpus 

 spongiosus. This species, which has only recently been restored 

 to the flora of southern New Jersey (see Bartonia, No. 17, 1935), 

 was here found profusely occupying a large tidal marsh along 

 with Pelta?idra virginica. It was in full flower on this date, its 

 white petals suggesting a Sagittaria, from which, however, its 

 blunt sepals arid thick, curved pedicels distinguish it. 



On the sandy beach below Elsinboro Point were collected 

 Tripsaciim dactyloides. Panicum amariim and Ammophila- brevi- 

 ligulata, all maritime species here at or near the inland limit of 

 their ranges, so far as concerns the Delaw^are drainage. 



The party then moved three miles down the river to a point 

 near the mouth of Alloway Creek, some three miles west of 

 Hancock's Bridge. Here, as might be expected (due to greater 

 proximity to the mouth of the Bay), an even larger number of 

 maritime species was encountered. In addition to the plants 

 already seen at Oakwood Beach and Elsinboro Point, the broad 

 sandy beach yielded Spartina cynosuroides, S. patens, A triplex
