40 MR. W. MITTEN—BRYOLOGIA OF THE SURVEY 
S. rufescens, Dicks., in a small state, was collected in Davis’s 
Straits by Mr. Taylor; and from the same region he brought 
another species, which will certainly be found in Europe when 
carefully sought for. It may be characterized thus :— 
S. RUBELLUS, sp.nov. Dioicus, czspitosus, ramis erectis parce ramosis, 
foliis imbricatis ovatis concavis apiculo brevi flexuoso marginibus 
revolutis nervis binis brevissimis, cellulis elongatis alaribus incon- 
- spieuis, perichetialibus imbricatis ovato-lanceolatis. 
Hab. Davis’s Straits, Taylor; Rocky Mountains, Drummond, inter- 
mixed with Catoscopium nigritum, Hedw. Sassar Pass, Nubra Moun- 
tains, Tibet, alt. 16,000-17,000 feet, Thomson. 
A small moss, with all the habit, appearance, and colour of 
Orthothecium intricatum, Bryol. Europ., but differing in its almost 
exactly ovate leaves, with a short, sometimes discoloured apiculus, 
the margins revolute, and the areolation composed of cells which 
are twice as wide. In the same particulars it differs from O. rufes- 
cens and O. chryseum. 
(Pylaiesia, Schimp.) 
S. POLYANTHUS, Schrad. 
Hab. Saskatchewan and Rocky Mountains, Bourgeau. 
This moss appears to be abundant in British America. 
(Drepanium, Schimp.) 
S. REPTILIS, Mich. 
Hab. Kootenay River, British Columbia, Lyall. 
S. PLICATILIS, sp. nov. Dioicus, fastigiate ramosus, foliis faleatis 
secundis late ovatis acuminatis hamatis siccitate ruguloso-subplicatis, 
nervis brevibus, marginibus reflexis integerrimis, in ramulinis apice 
serrulatis, cellulis ad angulos pluribus abbreviatis parvis obscuriusculis, 
superioribus latitudine coo longitudine € circiter uncie metienti- 
bus parietibus tenuibus, perichztialibus erectis elongatis internis late 
oblongo-lanceolatis apice subulatis integerrimis plicatis, theca in 
pedunculo elongato cylindracea basi erecta medio curvata, operculo 
conico, peristomio interno processibus luteis perforatis ciliis binis 
zequilongis nodulosis interpositis. 
Hab. Davis's Straits, Taylor; Rocky Mountains, Bourgeau. Also the 
* Hypnum cupressiforme 8. compressum," Sweden, Sommerfeldt, in 
Herb. Hooker, appears to be the male plant, but is much less than 
any of the American specimens. 
In size and general appearance the few specimens yet seen of 
this moss resemble Hypnum callichroum, Brid., and are pale yel- 
lowish green, the older parts brown; it differs from all the states 
of H. cupressiforme in the strongly reflexed margins of its leaves 
and short cells.
