in pedicello longo rubello, inclinata, elongato-obconica, sub ore sub con- 
stricta, rufescens, operculo mamillari rubello, annulo latiori, Peristomii

Hab. on moist rocks, Yosemite Valley. 
This fine species is somewhat related to B. pseudo-triquetrum, with which it 
grows, but easily separated by the enumerated characters. The ramification is the 
same as in B. Bigelowit, Sulliv., from which it differs by the long capsule and the 
form of the leaves. The top of the branches is purplish, abruptly crimsoned, as if 
it had been plunged in carmine.

Hab. on ground, rocks, old logs, very common in California, Gol., Dig., Brew. 
This species is most intimately related to L. capillare, Linn., presenting most of 
the forms which are marked as varieties in the European species. I owe to the kind- 
ness of Prof. Hooker, specimens of a Brywm named BL. eapillare, by Mr. Mitten, col- 
lected in Vancouver Island, by Lyall, and which is evidently a large form of L. ocei- 
dentale, and at the same time undistinguishable from B. eapillare. It would be too long 
to enumerate here all the varieties of ths California moss. The most marked one is a 
small form with slender innovations emerging from under more distinct and thicker 
capsules having with generally longer pointed leaves, narrow, cylindrical proportionally 
longer, broad red capsules and a proportionally broader annulus. But even the largest 
forms, whose capsules are generally pale brown and the leaves short, pointed, bear in 
the same tufts capsules of various color, from pale buff to dark red, with leaves also 
elongated or rather contracted into a piliform point. Though, from its larger annulus 
—especially its shorter pointed leaves and peculiar ramification—this species may be 
separated with some right from B. capillare, it does not appear possible to subdivide 
its varieties into species. One of these divisions is B. Baveri, Hampe, which, accord- 
ing to the author, differs from B. capillare; statura minori, folias brevisribus immarginatis, 
nervo excedente flexipilr.
