At Mission Doloips and on Jlonte Diablo {Bolandcr) ; Cnjon Pass and Colorado Valley 

 (Bigcloiv) ; Salt Lake, Utali (Jfafson) ; Britisli America {Drummond) ; and very common 

 tiuougiiout Eurojic and in Asia and Africa. Schimper unites the two species which have long 

 heen kejit apart upon tlie variations in tlie shape of the leaves and in the torsion of the pedicel. 

 Tlie ty|iical form (flie /'. Ilibcniiai) lias the more attenuate and more acutely serrate leaves, and 

 the pedicel twisted more or less to tlie h'ft. 



* * Capsule more or less nodding vpon an arcuate jyed led ; annulus present. 



3. F. hygrometrica, Iledw. Stems 3 to 10 lines liigh : upper leaves crowded 

 and connivent, or rarely spreading, broadly ovate-lanceolate, concave, entire, co.state 

 nearly to the apex, only the perigonial ones serrate at the apex and base : capsule 

 turgid-pyriform, deep yellow to red, horizontal or pendent upon a ilexuous arcuate 

 pedicel ^ to 3 inches long, deeply sulcate when dry and the very oblique margin 

 corrugated ; operculum broadly convex ; annulus large, at length unrolHng. — Bruch

Var. calvescens, Bruch k Schimp. Pedicel straight : capsule narrower and 

 nearly erect : loaves spreading, rather longer and narrowed, twisted when dry. — 

 /'. calvescens, Sclnvaegr. Suppl. t. G5. 



In various localities through tlie State {Covltrr, Bigclnw, rklrring, Bolandcr), and found in 

 nearly all parts of tlie world. Tlie varietj', wliich is more confined to warm regions, has been 

 collected in American P'ork Canon (Brciccr), and near Carson City, Watson. 



4. F. microstoma, Bruch k, Schimp. Diirering from the last in the stouter 

 pedicel, the firmer somewhat shining deep chestnut-colored capsule, only obscurely 

 sulcate when dry, the margin of the much smaller orifice not corrugated, the inner 

 peristome rudimentary, and the spores a half larger. — Bryol. Eur. t. 306. 



At Soda Springs, on the Upper Tuolumne {Bolandcr) ; Illinois ; European. 



5. F. convoluta, Ilampe. Loosely cespitose, the stem with the pedicel an inch 

 high : outer leaves spreading with involute margins, the upper convolute and em- 

 bracing tho pedicel, oblong-ovate, acute, nearly entire, the costa reaching the apex : 

 capsulo ascending, at length nearly erect, obliquely pyriform, more or less plicate ; 

 operculum umbonato, acute : teeth broadly lanceolate, yellowish, the tips incurved. 

 — Linnjca, xxx. 455. 



In the Sierra Nevada, at 3,000 to 5,000 feet altitude, J. Bauer. Hampe compares this species 

 with var. calvescens of F. hygrometica, from which he differentiates it by the shorter leaves, the 

 smaller and thinner-walled cells, the acute umbonate operculum and the yellowish teeth. It is 

 to be inferred that the capsule is annulate. 



32. LEPTOBRYUM, Schimp. 



Stems low, cespitose, on the ground, simple or innovating from the base, rooting 

 only at base. Leaves numerous, linear-setaceous (the lower much smaller and 

 remote), with broad excurrent serrate costa, areolation linear-rhombic above, smooth 

 and shining. Flowers bisexual; paraphyses filiform, acute. Yimi ns in Bryum ; 

 but the stipitate sporangium much smaller than the cavity of the capsule. 



Only two species, the second Peruvian. 



1. L. pyriforme, Schimp. Stems | to 1 inch high : loaves soft and green, 

 with silky lustre, spreading, flexuose : capsule inclined or pendulous, ovate-pyriform 

 with long collum and convex apiculate operculum, thin, yellowish brown and .shin- 

 ing : ciliolcE present. — Coroll. Bryol. Eur., and Syn. 2 ed. 390 ; Wilson, Muse. Brit.
