A remarkable form, perhaps referable to this species, has been collected by 

 Mr. Bolander, on gravelly soil, near the Big Trees. It is subcsespitose, with a robust 

 stem branching by innovations generally in two, opposite, from one-half to one-inch 

 long. Its color is brownish yellow ; the leaves when dry are appressed or slightly tor- 

 tuous, open-erect by humidity, loosely imbricated, ovate lanceolate, very entire, revo- 

 lute on the borders, with a strong excurrent nerve-forming point ; the basilar reticula- 

 tion is equilateral, elongated, pellucid ; in the upper part of the leaves, the areolae 

 are opacpie, minute and minutely papillose. The capsule borne on a short, straight, 

 reddish pedicel of half an inch long, is large, oblong, of a reddish color, with an erect 

 pointed operculum half the length of the capsule. The teeth of the peristome are 

 red, twice twisted on a short membrane ; the annulus is double, pellucid or white ; 

 the male flowers terminal and thick. This form is more robust than any other of the 

 section of the Vineales, and is easily distinguished by its appressed. scarcely twisted 

 leaves, its thick, brown, reddish capsule on a proportionally short pedicel. The form 

 and areolation of the leaves are like those of B. vinealis; but the peristome is twisted 

 twice and dark red. The forms of this section of Barhula found in California are so 

 numerous, that it will be necessary to reduce them to a few species, or to make a 

 monograph of them, embracing more than one dozen species. I have only mentioned 

 in this catalogue the most marked forms.
