in tlie short pedicel, and the quadrate areolation of the upper 

 part of the leaves ; on the other hand, in the short pedicel of the 

 narrowly oval or subcylindrical caj)sule this species resembles 

 the last, from which it differs in the form of the leaves, the 

 color of the plants, the more regular division of the teeth of the 

 peristome, etc. A distinct very fine intermediate form. — Bot.

 Hab. rortland, Oregon {B. B. Nemos, 1873). 



Subgenus III. RACOMITRIUM, proper. 



Plants nodose by short numerous lateral fasciculate branches. 

 Male flowers lateral. Fruit acrogenous or sublateral. Teeth 

 generally divided into two long filiform segments. 



5. R. Sudeticum, Bruch & Schimp. Plants loosely cespi- 

 tose, dirty green, slender, naked below : leaves spreading, 

 divaricate, erect when dry, long-lanceolate, gradually acuminate 

 to a short pellucid denticulate apex : calyptra nearly smooth at 

 the apex : capsule on a short pedicel, very small in comparison 

 to the size of the plants, elliptical or obovate ; lid conical-ros- 

 trate, shorter than the capsule ; teeth purple ; annulus large, 

 revoluble. — Bryol. Eur. t. 204. Trichostomum Sicdeticitm^

 Falls (Watson); Alleghany Mountains {Siillivaut)] Fairmount Park, 

 Philadelphia {James); Stoney Creek, Pennsylvania (E. A. Bau); Cats- 

 kill and White Mountains, etc. ; not common. 



Easily confounded with B. patens, but distinguished by its more slen- 

 der stems, the upper leaves with diaphanous denticulate points, and the 

 capsule half as large, on a short straight or slightly inclined pedicel. 



6. R. heterostichum, Brid. Tufts more or less extensive 

 and irregular, grayish green ; plants long, dichotomous, erect or 

 prostrate ; branches somewhat fasciculate : leaves open or fal- 

 cate-secund, long-lanceolate, subulate to a pellucid remotely 

 dentate point, variable in length, more or less plicate : calyptra 

 papillose at the aj^ex only : capsule elliptical or obovate, thin, 

 slightly constricted under the orifice when empty, yellowish 

 brown ; lid ei'ect or curved, subulate, half the length of the cap- 

 sule ; teeth variable in length ; annulus large, yellow. — Muse.
