 Hocks, Mission Dolores, &c. 



45. Aulacomnium a. ti d r o gy n u ra ScJur. 



On my Californian specimens, the male flowers are disciform as Bridel indicates it, and 

 not gemmiform as is generally the case in the European specimens. The brown antheri- 

 diae and filiform paraphyses arc very numerous. On old logs of Sequoia v i r i d i s ; 

 appears to be common in California. April. 



46. Bryum Tozzcri Grcv. 



Deep shaded ditches near San Francisco. 



47. Bryum Wahlenbergii Sahw. 

 Wet rocks, San Francisco. May. 



48. Bryum Billarderii Schw. 

 Deep Canon, Mount Diablo. May. 



49. Bryum Oaliforniou ta Sul. 



In its full development, the cilioli of the internal peristome are long, mostly two together, 

 and appendiculate. Common in the hills of Oakland on ground, in meadows near shrubs. 

 April. 



50. Bryum occidcntalc Sul. 



Like its near relative Bryum ccespiticiwm, this species is very variable. The ramification 

 is from below and around the first fruit-bearing bud. The branches more or less nume- 

 rous, nearly naked below, arc cither short, bearing at the top a thick bud of closely im- 

 bricated, short ovate, pointed, concave leaves ; or, on sandy wet soil, become elongated, 

 flagelliform, bearing distant, lanceolate, narrow, pointed leaves. The color of the capsule 

 is as variable as its size. It is more generally blood red, but in the shade, it is either 

 buff colored, or even greenish or variegated, half red, half brown. On sandy soil and 

 rocks near the Bay of San Francisco.

In woods, Oakland. Sterile. 



52. Mnium Mcnzicsii 0. MUll. 



Shaded banks of a creek, Marin County. April, 18G3. 



53. Bartramua striota Brkl. 



Differs only from the normal form by the pedicel round-oval at the top, and not square.
