FONTINALE^E. 



FONTINALIS CALIFORNICA, (sp. nov.) : caulibus flaccidissimis multoties divisis raraosis, ubique * 

 foliosis ; foliis concavis patentibus distantibus late ovalibus laxiuscule areolatis, cellulis utriculo 

 primordiali subsoluto instructis ; fructu non viso. Rivulets in t"he coast range of mountains 

 north of the bay 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 -j-J-j of a line, not T -J- T , as erroneously stated in the second edition of Gray's 

 Manual of Botany.

antheridiis numerosis copiose paraphysatis ; fructu ignoto. Coast range of mountains south of 

 San Francisc >. 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.) v 



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.
