NOTES ON CALIFORNIA BRYOPHYTES. III. 91 



Hedwigia albicans (Web.) Lindb. (H. ciliata Ehrh.). 

 Ascribed somewhiit doubtfully to California in the Geological 

 Survey Botany, but occurs on rocks about Berkeley, Mt. Tamalpais, 

 and in various other localities. 



Hedwigia albicans (Web.) Lindb., var. detonsa, n. var. 

 Pericluetial leaves entire or slightly denticulate ; stem leaves diaph- 

 anous at apex for \-\^ the inner perichsetial sometimes for one-half 

 their length ; margins plane or very slightly reflexed at base ; 

 calyptra usually glabrous. On rocks. Shasta County: Oak Run and 

 Morley's Station, M. S. Baker and F. P. Nutting. Also collected 

 later by the writer at Pieta, Mendocino County, and on Mt. Diablo. 

 We now have this plant from four different stations and it differs 

 constantly from Hedwigia albicans in the entire absence of cilia on 

 the mai-gins of the pericha3tial leaves. It is quite possible that it 

 deserves si^ecific rank, but, as we find no other constant character 

 to distinguish it and as the ciliation in H. albicans is somewhat 

 variable, we prefer, for the present, at least, to regard it as a variety. 

 Kindberg's sub-species submcda appears to be not very closely akin, 

 for in this, at least as represented in Can. Muse. No. 615, the 

 perichsetial leaves are quite well provided with cilia. Our variety 

 is possibly identical with Hedwigia ciliata epilosa, referred to by 

 Schimper in a note on p. 285, Syn. Muse. Europ., vol. ii ed. 2, but, 

 that, so far as we have been able to discover, is a nome?i nudum. 



Braunia Californica Lesq. Mt, Tamalpais; Sims and Oak Run^ 

 Shasta Co.; the var. pilifera (Mitt.) L. & J. at Oak Run and also 

 near Hay Fork. 



Ancectangium Calif ornicum (BLampe) McClatchie. (Zygodon 

 Californicus Hampe.) On shaded perpendicular rocks at Ukiah, 

 abundantly fruiting; also in the San Gabriel Mts., A. J. McClatchie 

 (sterile). 



Leersia rhabdocarjm (Schwaegr.) Lindb., var. Upper leaves 

 with a smooth hyaline hair point, sometimes 1 mm. long, yellow 

 only at base; capsule rather longer and narrower than in European 

 specimens. On lava rocks near Egg Lake, Modoc Co., June 8, 

 1894, M. S. Baker and F. P. Nutting, New to California. 



Physcomitriuvi Californicum E. G, Britton. Beside rivulet 

 near Hyampum, Trinity Co. Determined by Mrs. E. G. Britton.
