near the foot of San Francisco mountain, Mogollan range, which apparently belong to 
0. cupulatum. 
GRIMMIE2E. 
Schistidium apocarpum, Bryol. Europ. ScMstid. monogr., p. 7, t. 3. —On rocks at the crossing 
of the Rio Colorado. 
Grimmia Californica, (sp. nov.): dioica ; laxe caespitosa ; folds erecto-patentibns elongato- 
lanceolatis carinoto-concavis margine revolutis, costa in acumen liyalinum denticulatum 
excurrente; capsula ovali oblongave, sub-pyriformi pendula, sicca vix costata; pedicello 
breviusculo arcuato ; operculo recte longe rostrato ; calyptra dimidiato-mitriformi basi 4—5 
fissa ; annulo majusculo triplici; peristom. dentibus bifidis.—Oakland, opposite San Francisco; 
also near Sonora. Approaches near to G. trichophylla, Grev.; but that has less crowded, 
longer, more slender, and flexuous leaves, and capsules distinctly and prominently ribbed when 
dry, with subflexuous and longer pedicels. 
G. Olneyi, Sulliv ., a more closely related species, is not so robust; has leaves canaliculate- 
concave not recurved on the margin ; when flattened, linear-lanceolate from an ovate base, 
and the teeth of the peristome perforated (not bifid) at their apices. 
G. Californica differs from both species in the more or less obovate outline of its capsule, 
with an evident collum. 
In the same habitat occurs a variety differing from the typical form in the strong recurvation 
of its leaves, an unusual feature in this genus, and which is to be found in only one other 
published species, the Algerian Grimmia ancistrodes, Mont., which, according to original 
specimens from Dr. Montagne, is likewise dioecious, not monoecious, as stated in his Sylloge. 
This variety may prove to be a distinct species. (Plate IY.)

Benicia.

a Grimmia agreeing very well with G. commutata ; locality not mentioned. 
HEDWIGIEiE.

head waters of Bill Williams’ fork, near the Aztec Pass.

Downieville, on the Yuba river.

of the Sierra Nevada.- 
BRYE/E. 
Aulacomnion androgynum, Schiucegr,; Bryol. Europ. Aulacom., monogr., p. 11, t. 4.—On the 
ground, or on much-decayed logs. A common species in Oregon and California, somewhat 
larger than the European form, and, unlike it, fruits copiously.

B. Bigelovii, (sp. nov.): dioicum ; laxe crespitosum elatum multoties innovando-ramosum ex

imbricantibus erecto-patentibus oblongo-ovatis (comalibus lanceolato-acuminatis) concavis mar- 
gme subintegro vix recur vis, costa valida percurrente vel infra apice m desinente ; capsula alte
