On earth in the streets of Ottawa, Ontario, Fletcher. Differs 
from P. turbinatum in the broader leaves? Macoun’s number 597 
Canadian mosses was distributed as P. pyriforme, from two locali- 
ties, Windsor and Sandwich, Ontario, May 24, 1892. It con- 
tains two species, growing together, P. turbinatum, a small slender 
form, scarcely mature, and P Drummond, a few large, ripe cap- 
Sules, with much thicker pedicels, and dark brown in color. _ 
If we turn to Renauld and Cardot Musci Americze Septentrion- 
alis, p. 31, we shall find that we have another tangle of new 
Rhames and old ones to deal with. Thanks to the generosity of 
M. Cardot, I have been favored with authentic specimens of all 
his types of this genus and have been able to make some very in- 
‘cresting comparisons and corrections. Their check-list enumer- 
ates P. pyriforme, Brid., as an American species, and after calling 
his attention to my views, M. Cardot still maintains that it is, and 
Sends me a portion of his set, S. & L. Musci bor. Am., Ed. IL, 
No. 234, as an example. I have compared his and ours with 
European specimens and am still forced to differ from him, for 
reasons already stated. 
Three varieties are listed: 
“Var. tortipes (Brid.) Sine loco.” The specimens referred to in 
the Manual under this name are Drummond’s No. 25 from Apala- 
chicola, Fla., though this is probably not the form so named by 
Bridel, whose Specimens came from Pennsylvania. 
“Var. Jloridanum, R. & C. A forma typica foliis longioribus 
longius acuminatis, magis serratis capsulaque ore valde dilatato, 
vacua Cupuliforma, diversa.” 
We presume he means by “forma typica” the European wy tae 
cies. In a letter received October 18, 1893, he sends me this 
Variety as €qual to P. turdinatum, admitting my conclusion as far 
aS these Specimens are concerned and dropping this varietal asia | 
Vat. Langlois, R. & C. Bot. Gaz. 94, 1889, N. J-, La.” 
We have examined the specimens collected by Langlois and 
authenticated specimens from Cardot. They are unlike any 2 
orthern specimens in their ldng, slender pedicels, narrow, tur-
