 male flower gemmiform, axUlary. — Kocks, Lake Superior, Agassiz: Jefferson 

 County, New York. (Eu.) 



2. E. rhabdocdrpa, Schwsegr. 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. 11.) (Eu.) 



3. E. COllllllllta.ta, Nees & Homsch. Stems more slender than in No. 

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

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

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

 noecious. — British America, Z)rM»imoKc?. (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 Axuenca., Drummond. — The Alleghany specimens usually 

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



29. SYRRHOPODON, Schweegr. (Tab. H.) 



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

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

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

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

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

 representatives of Encalyptese), with densely csespitose simple or dichotomously 

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

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

 opaque, and granulose. (Name from (rvpponos, connivent, and oScoz/, a tooth, 

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



1. S. Floridanus, Sulliv. Stems about V high; leaves erect-patent 

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

 rowly bUamellate, undulated, seixated ; costa ceasing at or below the obtuse

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