have the shape of minute balls. A. palustre (L.) Schw. also pro- 
duces pseudopodia which bear at their apices gemmiform “Brut- 
blätter,” but the latter are obviously merely small metamorphosed 
leaves and are not at all like the gemmae of A. androgynum. 
PrirtoNoris marcHica (Willd.) Brid. (= P. Muhlenbergii Schw.) 
Although P. fontana (L.) Brid. is the only species of the genus credited 
to Connecticut in the 1908 list, P. marchica should also have been 
included. ‘This had been reported from the state (as P. Muhlenbergii) 
by Renauld and Cardot,' but the reference was overlooked. The 
specimens upon which this report was based were collected in Corn- 
Wall (1887) by Prof. H. A. Green and were determined by Cardot. 
The writer has recently collected it in Salisbury also. In the opinion of 
both Cardot * and Dismier * P. Muhlenbergii is not distinct as a species 
from P. marchica. P. marchica ranges throughout the northern 
United States and Canada and has been reported from all the New 
England states except New Hampshire. 
PuiLoNorIS cAESPITOSA Wils. In connection with a revision of 
the North American species of Philonotis which he has just completed, 
Dismier has kindly examined all the available Connecticut material 
of this genus and finds that a number of specimens which have passed as 
P. fontana should be referred to P. caespitosa. Previous to Dismier's 
critical study of the genus this species had not been recognized as 
occurring at all on the North American continent, although it was 
known to be not uncommon in Europe and had been reported from 
Greenland. Apparently, however, it is widely distributed, at least 
through the eastern half of the continent. Dismier reports it from all 
the New England states but Vermont, and in the herbarium of the 
New York Botanical Garden are specimens from New York, New 
Jersey, Pennsylvania, Ohio, and Wisconsin, as well as from Newfound- 
land and New Brunswick. The Connecticut stations are: Salisbury 
and Stafford (G. E. N.), Canterbury (Mrs. Hadley), Easton (Eames), 
Huntington and Hamden (G. E. N.), New Haven (Eaton, 1856), 
and Ledyard (G. E. N.). 
The characteristics by which the Connecticut species of Philonotis 
may be distinguished are indicated in the following key: 
1. Marginal teeth of stem leaves always wre isha and — papillae situated 
at the upper angles of the leaf cells . . . T . P. marchica.
