10 Rhodora [JANUARY 
and North Stonington (G. E. N.). Reported from New Hampshire ! 
and Massachusetts?; also from Maryland and Georgia?; Alabama 
and Louisiana *; Missouri *; Ohio 5; British Columbia ?; endemic to 
North America. 
According to Cardot's classification, of the various species thus far 
recorded from Connecticut F. antipyretica and F. Novae Angliae are 
referred to the first rank; F. Sullivantii is a second rank species sub- 
ordinate to the southern F. disticha Hook. & Wils.; F. dalecarlica is a 
third rank species related to the European F. squamosa L.; F. Allenii 
is a third rank species derived presumably from F. Novae Angliae; 
while F. nitida, F. Duriaei, F. Lescurii, and F. flaccida are accorded 
first, second, third, and fourth ranks respectively, being subordi- 
nated to F. hypnoides Hartm., a species which is widely distributed 
in Europe and which also occurs in the western part of this continent. 
A revised key to the Connecticut species of Fontinalis, largely 
adapted from Cardot, is here given.
