This species is evidently the one described by Turner, and collected by Menzies in Cali- 

 fornia in 1792, as shown by original specimens preserved in Taylor's herbarium, and 

 kindly furnished to me for comparison by Mr. Win. S. Sullivant. The above-described 

 modifications of the peristome would at first lead to the belief that there are two different 

 species, the one without, the other with a simple peristome. But on the same specimen, I 

 have found some capsules with a simple peristome of sixteen irregular, brown-reddish 

 teeth ; others with the pellucid peristomatal membrane, either simple and entire, or broken 

 in short laciniae without definite shape, and more or less united together, or with the 

 same membrane divided into sixteen lacinise already taking the shape of irregular teeth, 

 but still preserving the pellucid tissue of the membrane. It is therefore evident that 

 some peculiar influence, causing a more or less perfect development of the plant, is the 

 only reason of the difference. The oval form of the capsules is more or less elongated, 

 sometimes nearly round ; except this all the characters are perfectly alike. This remarka- 

 ble variation in the peristome exemplifies the value of Schimper's assertion in the Bryo- 

 logia Europea ; that little reliance can be put on the peristome of the Bartramiae to found 

 generic divisions. We have here both the genera Glyphiocarpus BriJ. and B a r- 

 t r a m i a Auct. united in the same species. 



According to Mr. Bolander, this Bartramia is very common in California, growing 

 on rocks, Mission Dolores, Marin County, Mount Diablo, &c.
