SOME ADDITIONS TO THE RHODE ISLAND FLORA. 
M. L. FERNALD. 
No well settled area of New England, except perhaps New Hamp- 
shire (outside the White Mountain and Monadnock areas), has a 
more meagre representation in the larger herbaria than Rhode Island. 
Members of the New England Botanical Club, who have spent much 
time in preparing the Check Lists of various groups, have experienced 
great difficulty in finding satisfactory evidence of the occurrence in 
these states of many of the widely distributed species. It is therefore 
desirable that whenever opportunity offers collections from these 
states be made and placed in the Club Herbarium or in other public 
or semi-publie collections. On June 19 last the writer, while spending 
the day at Buttonwoods Beach in Warwick, Rhode Island, was im- 
pressed with the number of plants which might prove of interest to 
students of plant-distribution; but as he was not equipped to preserve 
specimens at that time delayed the gathering of most species until the 
following Saturday, June 25, when with Mrs. Fernald he made a half 
day's collecting trip from Warwick Station (electric) to Buttonwoods. 
The region is in the sandy flat coastal belt and the vegetation is very 
typical of such areas, so that no detailed account of the flora is called 
for; but in labeling the specimens collected the writer finds that 
thirteen of them are of species or varieties which have not been pre- 
viously recorded from Rhode Island, or at most have been included 
without statement of locality in general manuals or similar works. 
These plants are here noted not because of their rarity but that 
records of their occurrence in the state may be accessible to future 
workers. 
PANICUM DICHOTOMUM L. Oak woods, Buttonwoods. 
Panicum LiNDHEIMERI Nash. Sterile meadow near the border 
of a salt marsh, Warwick. 
Juncus prcHOTOMUs Ell, var. PLATYPHYLLUS Wiegand. Sandy 
thicket, Warwick. 
SISYRINCHIUM GRAMINEUM Curtis. Abundant in meadows at 
the edge of a salt marsh, Warwick, the flowers much deeper blue- 
purple than in the following.
