NOTES ON CALIFORNIA BRYOPHYTKS. — III. 93 



Leiicolepis acanthorieura (Sclnvaegr.) Lindb. (Mniuni Meuziesii 

 Muell.) Not uncommon on shaded banks of streams and moist 

 rocks in Sonoma, Mendocino, and Humboldt Counties, Has also 

 been collected in the counties of Marin and San Mateo, but is 

 apparently rare south of Snn Francisco. It occurs in the Mt. 

 Shasta region, too, but poorly developed. 



Pogonaium alpinum (L.) Rohl, var. ardicum (S\v. )? On 

 shaded rocks in Deer Creek Caiion, Russ and Graham's Ranch, 

 Humboldt Co. Plants 6-11 cm. high and always simple. Altitude 

 (est.) 1,000 ft. 



Polytrichum comni2ine L. In moist meadows near Eureka. 

 The first record of the occurrence in California of tliis widely dis- 

 tributed moss. 



Pterygophyllum lucefis Brid. On densely shaded banks of 

 streams near the water-line. North Fork of the Little River, Mendo- 

 cino Co., and about Eureka, Humboldt Co. (c. /?■.). Also collected 

 in California by Dr. Bolander, though not so reported, so far as we 

 know, in any bryological work of American authorship. 



Camptothecium megaptilum Sulliv. On shaded northern slopes 

 of the Hay Fork Mts., Trinity Co. 



Camptothecium Atnesice Ren. & Card. On moist bank, Mitchell 

 Canon, Mt. Diablo, mixed with C pinna tifidtun ; Rubio Canon, 

 Pasadena, McCIatchie; Sonoma, Mr. F. T. Bioletti. 



Brachytheciuvi lam,prochryseum, C. Muell & Kindb. Determined 

 by Dr. A. J, Grout. On log in a stream, Sisson, Siskiyou Co. 



Brachythecium velutirium (L.) Br. Sch. On logs and soil in 

 woods, Sisson. 



Isothecium Brewerianum (Lesq.) Mac. & Kindb. Common on 

 logs and rocks in San Francisco, Marin, Sonoma, and Mendocino 

 Counties. Our remark in Erythea (iv, 51, 1896) in reference to 

 connecting forms lietween Isothecium, stoloniferum. and /. Brewer- 

 ianum, was based upon erroneous conceptions of the two species. 

 The short leaf-cells characterize all forms of Brewerianum and 

 always, we believe, distinguish it from any form of stoloniferum. 

 Isothecium Howei Kindb. is a form of /. Brewerianum. 



Eurhynchium colpophyllum Sulliv. On trees with Alsia Cali- 

 foryiica, etc., Olema, Marin Co., — rao?^t\j,\n,Y. _flagelli/or7?ie Barnes.
