binate, almost campanulate capsules, and pale yellow color. We 
have it from several other Southern localities and collectors, and 
it maintains its individuality. We also have the specimens col- 
lected at Atco, New Jersey, by H. A. Green, which have also 
been referred by the authors to this variety, and some specimens 
collected in the vicinity of New York from wet localities, were 50 
named by M. Cardot.. We regret that he should not have main- 
tained this varietal name for the lax, pale, slender, Southern form, 
from which it was originally named, and not extended it to in- 
clude all our taller Northern ones, which are not at all constant, 
and are dependent on exposure, soil and moisture. 
* We are inclined to think that var. Langloisii is almost worthy 
of specific rank, and have figured it in order to call attention to it, 
and obtain more material. 
P. Hookeri var. serratum, R. & C. “A forma typica foliis 
dimidio superiore grosse et obtuse serratis distincta.” 
We have received from both Cardot and Henderson duplicates 
of the specimens on which the above variety was based. We 
cannot find the well differentiated annulus so characteristic of 3 
FHlookeri, and have since discovered that they are identical with — 
the specimens we sent to M. Cardot under two manuscript names 
from two localities; the first collected by Langlois in Louisiana, 
was named for that state, and the second collected by Jermy 
Texas was named for that state. Further comparison and study 
have convinced me that all three are identical with the specimens 
collected by Drummond near New Orleans and distributed 1 
1848 as. P. pyriforme, var. 3, No 24, of his Southern mosses. We | 
have named it PHyscomirrium Drummonpij, after the original coke 
lector, and rejected both our own manuscript names, as the specie 
is found to have a much wider range than we at first supposed. 
We wrote to M. Cardot, giving him our views on the ‘differ- 
ences between the European P. pyriforme and the American P. ™ 
binatum, and at the same time calling his attention to the fact that 
his var. serratum could not be referred to P. Hookeri, on acco 
of its simple annulus. He admitted the correction, and pnt 
ferred it to the American species, as P. turbinatum, var. crassipe He. 
m.s. This name has not been published, though we have given - 
him abundant time to do so, as it is over six months since OF
