 Hab. Fissures of rocks; most abundant in the mountains. June. 



2. A. Mougeotii, Schimp. Differs from the last in its 

 larger more pulvinate tufts, the plants slightly curling, yellowish 

 green above, ferruginous below, with few radicles : the leaves 

 longer and narrower, with borders recurved toward the base, 

 the perichcetial enlarged, not tubulose, sheathing near the base 

 only, narrower ; the capsule on a pedicel twice as long and dis- 

 tinctly emergent, the beak of the lid longer acicular ; and the 

 flowers dioecious. — Syn. 248. Zygodon Mougeotii, Bruch & 

 Schimp. Bryol. Eur. t. 206 ; Sulliv. 1. c. 



Hab. Wliite Mountains; Wissaliickon, near Philadelphia (James), 

 sterile. 



3. A. CalifornicurQ. Dioecious: plants soft and loosely 

 pulvinate, yellowish green above, ferruginous and radiculose 

 below: leaves very crispate and twisted when dry, spreading 

 and flexuous when moist, narrowly lanceolate, acuminate, 

 deeply canaliculate-carinate ; costa excurrent ; borders revolute 

 below, flat and remotely sharply denticulate above ; upper areo- 

 lation minute, quadrate, not inflated ; perichaetial leaves nar- 

 rower and more acute, not sheathing, slightly subrevolute on the 

 borders : capsule small, oval, urceolate, subexserted on a short 

 somewhat arcuate pedicel : male plants stouter. — Zygodon 

 Ccdifornicus, Hampe ; Muell. Bot. Zeit. xx. 361 ; Lesq. Trans. 

 Amer. Phil. Soc. xiii. 6 ; Sulliv. Icon. Muse. Suppl. 47, t. 32. 



Hab. On shaded rocks; San Jose Valley, California {Bauer); Darda- 

 nelles Caiion, etc. (Bolander); near the British boundary [Lyall). 



The fertile plants had not been discovered by Hampe, who considered 

 the inflorescence as probably dioecious. 



4. A. Sullivantii. Plants long, slender, flexuous, in loose 

 intricate yellowish brown tufts, beset with a few bundles of 

 radicles sometimes attached to the apex of the leaves : leaves 

 remote, recurved-sp reading, lanceolate from the slightly decur- 

 rent base, concave, entire, with borders reflexed up to the 

 middle, complicate, distantly serrate upward ; costa percur- 

 rent : flowei-s and fruit unknown. — Zygodon Sidlivantii, 

 Muell. Syn. i. 679 ; Sulliv. Mosses of U. States, 32, and Icon.
