branch-leaves smaller, subfalcate ; porigonial leaves open-erect 

 or somewhat spreading, flexuous, lanceolate-acuminate from a 

 broadly oval much enlarged base; perichaetial leaves longer, 

 striate, subulate : capsule ovate or subglobose, greenish yellow, 

 cernuous, on a short thick blood-red pedicel ; lid conical, acute ; 

 segments a little shorter than the teeth ; cilia none. 



Hab. Vancouver Island (Macoun). 



A slender delicate species related to P. Mnhlenhergii, differing in the 

 longer-acnininate subulate leaves, with shorter quadrate and less papillose 

 areolation, the perigonial leaves longer and acuminate, flexuous at the 

 point, etc. The form of the capsule is the same; the pedicel shorter, 

 thick, not geniculate at base. 



3. P. fontana, Brid. In wide more or less compact yel- 

 lowish green tufts; stems long, simple or dichotomous ; branch- 

 lets verticillate, nearly equal : leaves often of tAvo forms, either 

 small, ovate, obtusely pointed and apjjressed to the stems, or 

 larger, ovate-lanceolate, acute, erect and open or secund ; costa 

 excurrent into a sliort bristly point ; pericha3tial leaves linear- 

 lanceolate, plicate at the base, all serrate, pajiillose, glaucous- 

 green and opaque : male flowers broadly discoid ; inner peri- 

 gonial leaves ovate, lanceolate, spreading above the erect con- 

 cave base, blunt or subacute, densely serrate : capsule on a long 

 solid slightly flexuous pedicel, cernuous, ovate-globose, of thick 

 texture, striate, longer oblong and ribbed when old ; lid convex- 

 conical, acute ; teeth purple, lanceolate ; cilia two, as long as 

 the segments. — Bryol. Univ. ii. 18. Mnium fontanum., Linn.

Var. alpina, Brid. Plants short, densely foliate : leaves 

 shorter, ovate-lanceolate : capsule shorter pedicelled. 



Var. falcata, Brid. Branches curved at top : leaves longer, 

 falcate ; costa thick, light brown. 



Hab. On the borders of springs and rivulets, and on moist rocks; very- 

 common. The first variety on high mountains, the second near springs 

 in valleys and on mountains; not common. 



4. P. calcarea, Schimp. Much like the last, differing in 

 its thicker wider bright green tufts and more robust stems ; 

 leaves larger, crowded, secund or falcate-secund, ovate-lanceo- 

 late, those of the male branches often smaller and imbricate, 

 all loosely areolate with a stouter costa, the perigonium large 

 and open, and the involucral leaves long-lanceolate from an en-
