NOTE. Two more species and as many varieties of IJsoetes should 
be found within our limits. Marsilia quadrifolia, L., with four- 
parted leaves like an Ovzalis should also be found in some of the 
ponds and streams as it has been distributed many times from the 
Cambridge Botanic Garden. It grew abundantly with Trapa natans,

-Drvytsion I. MUSCI. MOSSES. 
(By Edward L. Rand.) 
The list of mosses here given is based mainly on the valuable 
collections of Messrs. Edwin and Charles E. Faxon. As these 
collections, however, were made mostly in the Blue Hills and 
Stony Brook Reservations, the moss flora of the other Reserva- 
tions is most imperfectly represented in the list,— in fact only 
two species have been reported from the Beaver Brook 
Reservation. 
The list of Sphagnacez is arranged in accordance with the 
articles of Dr. Carl Warnstorf in Vol. XV of Coulter’s Botan- 
ical Gazette. Synonyms, however, have been given when pos- 
sible to facilitate reference to Lesquereux and James’ ** Mosses 
of North America.” The lists of Andreseaceze and Bryaceze 
are arranged in accordance with the Manual of Lesquereux and 
James just mentioned, in the absence of a standard work of 
ready reference of a more recent date. 
Orpen I. SPHAGNACEZE. Pear Mosszs. 
SPHAGNUM, L. Prat Moss. 
S. Girgensohnii, Russ. 8S. strictwm, Lindb. 
B, rare. 
+ The Hepatic have been omitted, owing to the illness of Miss 
Cora H. Clark who was to have prepared the list.
