OF THE FORTY-NINTH PARALLEL OF LATITUDE, 45 
L. DELICATULA (Linn.). 
Hab. Saskatchewan, Bourgeau. 
L. cRisPIFOLIA, Hook. Musci Exot. t. 31. 
Hab. British Columbia and Pend Oreille River, Lyall; Vancouver 
Island, Wood. 
Tracuypus, Schw. 
T. NIGRESCENS, (Neckera) Sw. 
Hab. Lake Huron, in fruit, Todd ; also sent from Canada West, Emery, 
in Herb. Miles. 
The oceurrence of this species (which seems to be precisely the 
same as Swartz's, from a specimen in Herb. Hooker.) in a country 
so much further north, was at first regarded with some suspicion, 
but this is now entirely removed by the specimens recently col- 
lected by Mr. Emery. 
LEUCODONTACEE, Mitten, Musci Ind.

H. CILIATA, Ehrh. i 
Haub. Mooyie River (a branch of the Kootenay), British Columbia, Lyall. 
HEDWIGIA PILIFERA, sp. nov. Monoica, ramis ascendentibus laxe 
cæspitosis dichotome divisis ramulis superioribus abbreviatis, foliis 
subsecundis ovatis ovato-acuminatisque acumine diaphano, foliis 
ramulinis (flagelliformibus) pilo longo flexuoso terminatis marginibus 
integerrimis revolutis, cellulis parvis breviter oblongis inferioribus 
paululo longioribus basi fuscis dorso papillosis, perichætialibus erectis 
longioribus ovato-lanceolatis, theca in pedunculo gracillimo trilineari 
subglobosa ætate evacua sub ore amplo contracta circiter decempli- 
cata, calyptra elongata cucullata fusca levi. 
Hab. Vancouver Island, on rocks, Lyall. 
A little more slender than H. ciliata, Ehrh., but agreeing very 
nearly with it in general appearance. The younger portions of the 
stems are of a yellowish green, the older brown. The fruitstalk 
is very slender and pale red. The capsules, which are all old and 
empty, are contracted below the mouth, and the fruitstalk is 
affixed to their base without an attenuated neck. 
This species has been here referred to Hedwigia, although it 
belongs to that small group of species which has been named by 
M. Schimper Hedwigidium, differing from Hedwigia, as originally 
founded by Ehrhart on H. ciliata, in the more cucullate calyptra 
and the presence of flagelliform shoots; these last are represented 
in H. pilifera by short ramuli, with leayes having very long hair 
points, but in all the specimens these ramuli are not decurved,
