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

 male flower gemmifonn, axillary. Rocks, Lake Superior, Agassis: Jefferson 

 County, New York. (Eu.) 



2. E. rhabdocarpa, Schwxgr. Differs from the last by its longer- 

 pointed or piiiferous 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. cominutata, Noes & Hornsch. Stems more slender than in No. 

 1 ; leaves subsquaiTo.se, ovate-lanceolate, gradually long-acuminate, concave, 

 undulate on the margin ; areoloe 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. StreptOcArpa, Hedw. 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 16, 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. SYR RSI 6 POD ON, Schwajgr. (Tab. 16.) 



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

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

 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 Encalypteae), with densely caespitose simple or dichotomously 

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

 base composed of large pellucid rectangular areolce, which elsewhere are minute, 

 opaquo, and gnmulose. (Name from <rvppo7ros, connivent, and oo>i>, a tooth, 

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



1. S. Florida nus, Sulliv. Stems about 1' high; leaves erect-patent 

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

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

 apex. (Syr. albovagimitus, Hook, fr Wils. in Drum. 2d coll , No. 37.) Northern

TRIBE XII. ZYGODONTE.E. 



3O. 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) Orthotriehum. Perennial 

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

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