1907]  Riddle,— Notothylas orbicularis in Massachusetts 219 
Iris setosa Pall. Very common within reach of spray from the sea, 
but never competing with I. versicolor L., inland. 
Comandra livida Richards. Very common on Johnson's Beach 
bog, with Rubus Chamaemorus L., but there were no blossoms or 
fruit visible (July 6). This is the first New England station at sea 
level, as the other reports are from five granitic mountain tops (Mans- 
field, Clinton, Saddleback, Abraham and Katahdin). It occurs at 
sea level in New Brunswick and northward. 
Suaeda Richii Fernald. Common along the edges of the salt marshes. 
Montia Jontana L. Moist open woods, Roque Island. 
Empetrum nigrum, L. var. andinum DC. Common on the top 
of the sea-cliffs, in residual gravel, the branches frequently hanging 
down. The typical form of the species seems to grow only in peat- 
moss. (RHopora, IV, 196.)

NOoTOTHYLAS ORBICULARIS IN MassacHUsETTS.— On October 9, 
1907, while collecting with a class in Cryptogamie Botany, on the 
Wellesley College campus, I found a number of plants of Notothylas 
orbicularis (Schwein.) Sulliv. The Notothylas was growing on wet 
sandy soil, in company with Anthoceros, and equally abundant. Dr. 
A. W. Evans has confirmed my identification of the material. 
As there seem to be few specimens in herbaria, it may be worth 
while to record what is known of Massachusetts stations for the plant. 
Dr. Evans states that the only Massachusetts specimens, of which he 
knows, were collected at Cambridge, and are in the Underwood Her- 
barium. ‘There is but one specimen in the Cryptogamic Herbarium 
of Harvard University, having been collected by Dr. Farlow at New- 
ton, in a locality where now probably extinct. In addition to these 
specimens, Dr. Evans has found Notothylas at Falmouth, Dr. Farlow 
at Cambridge, and Dr. Thaxter at Waverley. In none of these cases, 
however, was material preserved. ‘To these should now be added the 
Wellesley locality. Specimens of this collection have been deposited 
in the Herbarium of Wellesley College, in the Herbarium of Dr. A. W. 
Evans, at Yale University, and in the Cryptogamic Herbarium of 
Harvard University. 
The records from the localities named above suggest that Noto- 
thylas is probably well distributed through Massachusetts and perhaps.
