BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 379 
August 18, 1910, in pine woods near Miacomet Pond, where a large 
number of plants were found. 
PERSICARIA HARTWRIGHTII (Gray) Greene. 
Polygonum Hartwrightu Gray. 
Muddy shore of Squam Pond, June 20, 1910, not yet showing 
any signs of flowering. Leaves oblong-lanceolate becoming strig- 
illose, many of them marked medially with a dark chevron; 
ocreae developing a foliaceous and spreading fringed margin. 
Growing sparingly in the water near the shore was a weaker gla- 
brate form with floating upper leaves and unmargined ocreae. 
*CHENOPODIUM GLAUCUM L. 
A specimen sent to me by Mrs. Flynn was collected near the 
railroad in the town August 7, 1911, in full flower. 
*SALSOLA PESTIFER A. Nelson. 
 Salsola Tragus L. 
Not observed before 1912 when two plants were found by 
street sides in the town, and a small colonyin an abandoned chicken 
paddock at Surfside. Just in flower July 9. 
*TETRAGONIA EXPANSA Murr. 
Prospect Hill rubbish dump, September 15, 1913, in flower. 
Specimen communicated by Miss Gardner. 
*SILENE CONICA L. 
Well established and in full flower and fruit in the corner of a 
field north of the town June 16, 1911; a single plant on a bank by 
the railroad beyond Orange Street, July 18, 1910. 
*SILENE NOCTIFLORA L. 
One plant in full flower in a weedy yard on Union Street, 
June 20, 1910. Collected by Mrs. Flynn June 28, 1895. 
*SILENE ANGLICA L. 
Specimens of this catchfly from Nantucket and reports of its 
occurrence there have reached me from several sources. It does 
not appear, however, that it has been found outside of a small 
garden and yard on Main Street where, quite probably, it had 
once been cultivated. I saw it there, evidently spontaneous, and 
scattered here and there like a garden weed.
