Resembling the preceding, branching stems often circinate when dry. Leaves 



smooth or papillose, the areolation minutely oval-rhombic and punctiform. Capsule 



cylindric, emergent or exserted ; operculum conic, long-beaked. Peristome double, 



the inner processes shorter than the teeth, upon a narrow basal membrane, with or 



without ciliola). — Proc. Amer. Acad. iii. 184.

1. A. Californica, Sulliv. On trees, in dark green masses; secondary stems 

 2 or 3 inches long, sub|nnnately branched, not circinate, somewhat arcuate, the 

 branches short, slender, not crowded : leaves erect-spreading, ovate- or oblong-lan- 

 ceolate, slightly serrulate at the apex, margins narrowly retlexed, costa ceasing below 

 the middle, areolation minute and sul-rhombic, sniooth ; leaves on the branches 

 smaller and narrower, the pericha'tial long and slender : capsule oblong-cylindrical, 

 straight or slightly curved, scarcely exserte<l ujion a short pedicel : inner processes a 

 third shorter than the teeth ; ciliohe none or rudimentary. — Muse. Wilkes Exped.

2. A. abietina, Sulliv. On trees, in loose rigid deep green masses ; secondary 

 stems 2 to 5 iiiclies long, simple below, exjianded above into a piunately or some-

 serrulate and slightly inllexed above, the costa ceasing below the ape.x, areolation 

 oval-rhombic, longer in the luiddle and cpiatlrate at the angles : capsule ovate-oblong, 

 emergent on a very short pedicel, ribbed when dry: peristome as in the last, but 

 ciliohe wanting. — Icon. Muse. 115, t. 72''; Sulliv. & Lesq. 1. c. 2 ed. n. 400. Neckera
