SPHAGNUM PSEUDOSQUARROSUM Warnst. “Connecticut, Oxford 
(Eaton).” Var. heterophyllum Warnst. Oxford (Eaton, 1893).! Var. 
bicolor Warnst. Oxford (Eaton, 1893).? 
SPHAGNUM BAVARICUM Warnst. In pools, altitude 27 m., North 
Stonington (G. E. N., 1912). A submersed form heretofore included 
as a variety under S. subsecundum. 
SrHAGNUM NicHoLsu Warnst. Submerged in shaded pools of a 
mountain swamp, altitude 570 m., Salisbury (G. E. N., 1912). 
Although in habit this moss resembles S. cuspidatum, it is obviously 
related to S. inundatum, from which it differs primarily in the fact 
that the hyalodermis of the stem consists of usually two (1-3) layers 
of cells instead of but one. From S. contortum and S. platyphyllum, 
the only other Connecticut species with which confusion is likely, 
S. Nicholsii may be distinguished by the shape of the chlorophyll cells 
in the branch leaves. In the two first mentioned species these are 
rectangular or barrel shaped in cross section whereas in the present 
species they are triangular or trapezoidal. 
SPHAGNUM TURGIDULUM Warnst. East Haven (Eaton, 1893). 
Distributed by Eaton & Faxon? as S. rufescens, a species to which 
it bears a marked resemblance. 
SPHAGNUM SUBBICOLOR Hampe. (S. papillosum Lindb., var. inter- 
medium Warnst.) East Haven (Evans, 1891). The status of S. 
subbicolor has been discussed somewhat at length by Andrews * who 
considers it an artificial species designed to embrace intergrading 
forms of the two closely related species, S. magellanicum Brid. (S. 
medium. Limpr.) and S. palustre L. (S. eymbifolium Ehrh.). 
SPHAGNUM MACROPHYLLUM Bernh. Floating in ponds, altitude 120- 
150 m., Voluntown (G. E. N., 1912). There are a number of reasons 
why this moss is of unusual interest. In the first place the general 
appearance of the plant is strikingly different from that of any other 
Connecticut species — in fact, at first sight, it does not look like a 
Sphagnum at all; for the leaves, instead of being imbricated, spread 
at a wide angle from the branches, and the majority of the branch 
leaves are very large, attaining a length of 12 mm. or even more with 
a width of about 2 mm.; they have a glossy, metallic lustre when dry
