220 Rhodora [NOVEMBER 
Two ADDITIONS TO THE FLORA or Ruopg IsLAND.—In October, 
1924, the writer collected in Rhode Island two plants that apparently 
have not been reported as occurring in the state. One of these, 
Tridens flavus (L.) Hitche., was found on the slope of Neutaconkanut 
Hill, Providence, under conditions strongly suggesting that the 
plant had not been introduced. Gray’s Manual (1908) gives the 
range as " Ct. to Mo. and southw." Since then this grass has been 
reported from Nantucket, Martha's Vineyard and Southboro, 
Massachusetts (see RHopora 16: 82, May, 1914), and it has been 
collected elsewhere in Massachusetts. 
The other plant is Polygonum puritanorum Fernald. This was 
collected in a sandy cart-path through a salt marsh near Point Judith, 
South Kingstown. It has been reported from various stations on 
Cape Cod, Massachusetts (Fernald in RHODORA 21: 141, August, 
1919).—J. FRANKLIN CoLLINs, Providence, Rhode Island. 
Vol. 26, no. 310, including pages 181 to 200 and plates 146 to 148, was issued 
15 December, 1924.
