 Root tomentose. Stem 1-2 inches in height, erect, or 

 frequently decumbent for the greater part of its length, 

 simple, occasionally slightly branched by innovation, 

 covered with reddish down. Leaves mostly expanding at 

 the summit of the stem, as in B. rostratmn, but there are 

 also a few of a smaller size scattered remotely on the stem. 

 In form they are oblong-obovate, attenuated considerably 

 at the base previous to insertion, more or less acute, some- 

 times even obtuse, undulated, marginated, furnished with 

 serratures, or rather cilia?, which are spreading, cylindri- 

 cal, and articulated ; nerve shortly excurrent, and so strong 

 as to give the leaves an arched form when dry. Seta near 

 two inches long, pale yellow above, shining, deep red- 

 brown below. Capsule oblong, ventricose, pendulous, 

 pale yellowish, sometimes reddish at the base, the orifice 

 surrounded by a cartilaginous orange line. Lid between 

 conical and hemispherical, pale yellow, or tinged with 

 orange, the apex minutely mammillose and fine red. 

 Peristome ; outer one composed of yellow teeth subulate at 

 their apex ; inner one of 32 segments rounded towards the 

 points, and becoming abruptly subulate, with alternating 

 cilise.

 in some points, that I at first regarded them as identical. 

 They do, however, differ in several remarkable features, and 

 upon consulting the specimen published as B. affine by 

 Funck, in his beautiful " Deutschlands Moose," I became
