A remarkable form, perhaps referable to this species, has been collected by 
Mr. Bolander, on gravelly soil, near the Big Trees. It is subcespitose, 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 areol 
are opaque, 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 Barbula 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.
