At Mission Dolores ami on Monte Diablo (BoJander) ; Cajon Pass and Colorado Valley 

 (Birjelow) ; Salt Lake, Utah ( IVatson) ; J5iiti.sli America {Drumvtond) ; and very connnon 

 throughout Europe and in Asia and Africa. Schimper unites the two species which have long 

 been kept apart upon the variations in the shape of the leaves and in the torsion ol the itedicel. 

 Tlie typical form (the F. Hibcvnica) has the more attenuate and more acutely serrate leaves, and 

 the pedicel twisted more or less to the left. 



* * Capsule more or less nodd'uKj ujjon an arniate pedicel ; anmdus present. 



3. F. hygrometrica, Hedw. Stems 3 to 10 lines high : upper leave.s crowded 

 and couniveut, or nuvly spreading, broadly ovate-lanceolate, concave, entire, costate 

 nearly to the apex, only the perigonial ones serrate at the apex ami base : cap.sule 

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

 pedicel i to 3 inches long, deeply sulcate when dry and the very oblicpie margin 

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

Var. calvescens, Bruch & Schimp. Tedicol straight : capsule narrower and 

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

 F. calvescens, Schwaegr. Suppl. t. G5. 



, In various localities through the State {Coulter, Bigclow, Pickxring, I]oI(nida-),:\u,\ found in 

 nearly all parts of the world. The variety, which is more confined to warm regions, ha.s been 

 collected in American Fork Canon (Brewer), and near Carson City, Watson. 



4. F. microstoma, Bruch & Schimp. Differing 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. 30G. 



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



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

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

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

 capsule ascending, at length nearly erect, obliquely jiyriform, more or less plicate ; 

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

 — Linna^a, xxx. 45-5. 



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

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

 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. Fruit as in 2>';-y?m; 

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

 Only two species, the second Peruvian. 



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

 with silky lustre, spreading, flexuose : capsule inclined or pendulous, ovate-]\vriforni 

 with Ion" collum and convex ai)ieulate opeiv.ulum, thin, yellowisli brown and slim- 

 ing : cilioke present. — Corull. Bryol. Eur., and Syn. 2 ed. 390 ; Wilson, Musr. Bnt.
