2. A. Calif ornica, Sulliv. Xear the last : branches shorter, densely leafy : 

 leaves appressed when dry, rather shortly acuminate, entire or scarcely serrulate at 

 the apex ; areolation of shorter oval cells, nearly uniform throughout : capsule cylin- 

 dric, reddish, on a shorter straight pedicel : teeth longer, minutely punctulate, the 

 processes much shorter. Lesq. Trans. Anier. Phil. Soc. xiii. 1 1 ; Sulliv. & Lesq.

Resembling the preceding. Branching stems often civcinate when dry. Leaves 

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

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

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

 without ciliolse. Proc. Anier. Acad. iii. 184. 



An American genus of three species, nearly allied to Lcptodon, Weber (Lasia, Beauv.), and in- 

 termediate between Neckera and Thuidium. 



* Capsule very shortly pedicelled. 



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

 2 or 3 inches long, subpinnately branched, not circinate, somewhat arcuate, the 

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

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

 the middle, areolation minute and subrhombic, smooth ; leaves on the branches 

 smaller and narrower, the perichaetial long and slender : capsule oblong-cylindrical, 

 straight or slightly curved, scarcely exserted upon a short pedicel : inner processes a 

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

Very common along the coast, Pickering, Bigelow, Bolander. 



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

 stems 2 to 5 inches long, simple below, expanded above into a pinnately or some- 

 what bipinnately branched frond, strongly circinate when dry : leaves erect-spreading, 

 lanceolate, shortly papillose on the back above the middle, margins below recurved, 

 serrulate and slightly inflexed above, the costa ceasing below the apex, areolation 

 oval-rhombic, longer in the middle and quadrate at the angles : capsule ovate-oblong, 

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

 ciliolae wanting. Icon. Muse. 115, t. 72 b ; Sulliv. & Lesq. 1. c. 2 ed. n. 400. Neckera

Common in the Coast Ranges from south of San Francisco to Vancouver Island. 

 * * Capsule long-pedicelled. 



3. A. longipes, Sulliv. & Lesq. Diffusely cespitose, grayish green ; secondary 

 stems 3 to 5 inches high, pinnately and bipinnately branched from the base : leaves 

 oblong-lanceolate, acute, coarsely serrate above, margin slightly recurved, costa ceas- 

 ing above the middle and denticulate on the back at its apex, areolation minutely 

 oval, smooth ; pericheetial leaves abruptly filiform-attenuate : capsule cylindrical, 

 upon a pedicel nearly an inch long, straight : teeth and processes very narrow, the 

 latter a little shorter and dehiscent along the keel ; ciliolae (1 or 2) appendiculate.
