line, capsule smooth ; annulus none ; calyptra fringed at the hase : monoecious ; 

 male flower gemmiform, axillary. — Rocks, Lake Superior, Agassiz: Jefferson 

 County, New York. (Eu.) 



2. E. rlialMlocarpa, Schwaegr. Differs from the last by its longer- 

 pointed or piliferous leaves, and longitudinally ribbed capsule; annulus present; 

 calyptra not fringed at the base ; peristome and inflorescence the same. — British 

 America, Drummond. (Tab. 16 ) (Eu.) 



3. E. couiiiauf fata, Nees & Hornsch. Stems more slender than in No. 

 1 ; leaves subsquarrose, ovate-lanceolate, gradually long-acuminate, concave, 

 undulate on the margin ; areolae very small ; costa excurrent ; capsule smooth ; 

 peristome none ; annulus simple ; base of the calyptra uneven, not fringed : mo- 

 noecious. — British America, Drummond. (Eu.) 



4. E. strej»t©c;arpa, Iledw. Stems more elongated than in No. 1 ; 

 leaves not so spreading, ligulate, costate to the obtuse or cucullate apex ; cap- 

 sule spirally ribbed ; peristome double ; teeth 1 6, filiform, nodose ; annulus 

 compound ; calyptra spinulose at the apex, crenate at the base ; inflorescence 

 dioecious. — British America, Drummond. — The Alleghany specimens usually 

 referred to this species are without fruit, and hence doubtful. (Eu.) 



29. SYRRIIOPODON, Schwsegr. (Tab. 16.) 



Calyptra large, campanulate-conic, rostrate, cloven on one side. Operculum 

 conic, with a long-subulate rostrum. Capsule elliptic-cylindrical, cxannulate, 

 exsertly pedicellate. Peristome single: teeth 16, linear-lanceolate, articulated, 

 without a medial line, short, nearly horizontal, inserted below the mouth of the 

 capsule. Inflorescence dioecious or monoecious. — Perennial plants (the tropical 

 representatives of Encalypteaj), with densely ca?spitose simple or dichotomously 

 branched stems, and costate elongated-ligulate leaves, from a whitish sheathing 

 base composed of large pellucid rectangular areola?, which elsewhere are minute, 

 opaque, and granulosa. (Name from o-vpponos, connivent, and oSow, a tooth, 

 alluding to the horizontal position of the teeth of the peristome.) 



1. S. Floi'idaaus, Sulliv. Stems about 1' high; leaves erect-patent 

 from an amplexicaul base ; the margins convolute, thickened, more or less nar- 

 rowly bilainellate, undulated, serrated ; costa ceasing at or below the obtuse 

 apex. (Syr. albovaginatus, Hook. Sp Wils. in. Drum. 2d coll , No. 37.) — Northern 

 shore of the Gulf of Mexico ; also Florida : frequent. (Tab. 16.) 



Tribe XII. ZYGODONTE^. 



30. ZYGODOIV, Hook & Tayl. (Tab. 16.) 



Calyptra small, cuculliform, smooth, oblique. Operculum obliquely rostrate 

 from a conic base. Capsule pyriform, apophysate, striated, on a rather short 

 pedicel, immersed or exserted. Peristome either double, single, or absent ; when 

 present, constructed as in (the nearly related genus) Orthotrichum. — Perennial 

 species, growing on trees or on rocks, in large patches; stems with fastigiate 

 branches, fertile at the apex ; leaves linear-lanceolote, carinate, continuously
