FONTINALFJE. 
Fontinalis Californica, (sp. nov.) : caulibus flaccidissimis multoties divisis ramosis, ubique 
foliosis ; foliis concavis patentibus distantibus late ovalihus laxiuscule areolatis, cellulis utriculo 
primordiali subsoluto instructis ; fruct-u non viso. Rivulets in the coast range of mountains 
north of the hay of San Francisco. 
Resembles F. Eatoni, Sulliv ., but is a somewhat smaller plant, with more distant and spread¬ 
ing, shorter, broader, and less acuminated leaves of a looser areolation, composed of shorter and 
wider cellules, in which the primordial utricle is more or less conspicuous ; color reddish-brown 
or copperish. 
The species of this genus have each a peculiar aspect or facies, (difficult to describe,) which is 
little liable to variation in consequence of the uniformity of their habitat. Their sporules have 
a diameter of about t F-_ 0 f a line, not t a t , as erroneously stated in the second edition of Gray’s 
Manual of Botany.

Leptodon circinatus, (sp. nov.) : dioicus ; ramis primariis e rhizomate horizontali oriundis 
inferne nudiusculis superne dense frondiformi-pinnatis (siccitate circinatis) paraphyllosis ; foliis 
quinquefariam imbricatis erecto-patentibus lanceolatis acuminatis subcarinato-concavis evanidi- 
costatis dorso papillosis margine parum recurvis superne serrulatis, retis pellucidae areolis 
m.nutis chlorophyllosis ovali-rhombeis e costa radiatim seriatis alaribus subquadratis conferti- 
oribus ; floribus masculis substipitatis axillaribus secus racliim utrinque crebre dispositis ; 
antheridiis numerosis copiose paraphysatis ; fructu ignoto. Coast range of mountains south of 
San Francisc i. Grows in dark-green cushion-like masses. The main stem or rhizoma hard, 
woody, buried in the soft bark of trees, and throwing out at right angles numerous elastic 
primary branches—1| to 2 inches long—of which the lower half is simple, the upper expanded 
into a densely pinnated ovate frond, circinate when dry. The simply pinnate ramification of the 
primary branches, and the shape of the leaf, separate this species from its cogeners. (Plate I.) 
Antitrichia curtipendula, Brid.; Bryol. Europ. Antitric. monog.p. 2, t. 1. Oakland, oppo¬ 
site San Francisco. The specimens are without fruit, and differ from the normal form (which 
has likewise been found in California) in its julaceous branches, and shorter and more crowded 
leaves, resembling the var. Hispanica, which occurs mostly in the south of Europe. 
HYPNEAL 
Hypnum Bigelovii, (sp. nov.): dioicum, subdendroideum ; surculis e caule rhizomatoidea 
arcuato-ascendentibus fasciculato-ramosis, ramis ramulisque complanatis; foliis patentissimis 
bifariis elongato-oblongis breviter acuminatis apice serratis subplanis, marginibus uno latere 
inflexis, costa sub apice evanida, areolatione densa superne rhombea inferne oblonga parenchy-
