THREE ADDITIONAL PLANTS FROM NANTUCKET.— The following 
plants may be of interest as not being previously recorded from Nan- 
tucket. Specimens of Polypodium vulgare L. were found by Miss Grace 
Gardner of Nantucket last summer. Corallorhiza maculata Rat. 
was found by Mr. Nelson, a Cornell student, who spent the summer on 
the island. In 1909 I found some patches of Glaux maritima L. on 
Tuckernuck Island and in 1910 found an abundance of it in the marshy 
area about the south inlet of the Island. It spreads over a large area 
along the shore and is of the small-leaved typical form. Specimens 
of these three species are in the herbarium of the Nantucket Maria 
Mitchell Association at Nantucket.— JosepH A. CusHMAN, Boston 
Society of Natural History.
