BRYUM. 123 



as the same with Br. loreale. Of these plants indeed we 

 are so unfortunate as to possess no authentic specimens ; 

 but we 'think that Mohr's opinion upon them is fully con- 

 firmed by the figures above quoted, and lately published by 

 Schwaegrichen ; for they differ in no essential point from 

 our Br. turlinatum, which, as we have already observed, is 

 by Mohr united with Br. caspiticium. We have further 

 added to our list of synonyms the Bryum Schlticheri and 

 Br. longisetum ; the former indeed approaching nearer to 

 Br. ventricosum in its leaves, but agreeing with our plant 

 in its capsules ; thus being as it were exactly intermediate; 

 and the latter differing from Br. iurlnnatum in nothing but 

 the length of the fruitstalk. 



All the states of Br. turbinatum are more or less fur- 

 nished with innovations, as may be expected from plants 

 growing in wet places, and the stems vary much in their 

 length The capsule too varies somewhat in figure, but is 

 always pyrifonn ; and the whole plant is subject to great 

 difference in colour, according to its exposure, and to the 

 soil in which it grows. 



6. Br. nutans ; stems short ; leaves erect, lanceolate, acumi- 

 nated, serrated above, nerve reaching to the point ; cap- 

 sule oblongo-pyriform, pendulous. ((TAB. XXIX.)

This species is remarkable, when the capsules are ma- 

 ture, for the bright colour of its fruitstalks, and for the 

 narrow and glossy leaves, which in the barren shoots are 

 almost linear, and are always at the extremity of the stems, 

 the least broad. The capsules are subject to vary somewhat 

 in form ; but it is to be observed that they are more pyri* 

 form as they advance in age, and when in a dried state. 



7. Br. elongatum ; stems short; leaves erect, elongate- lance* 

 olate, acuminated, serrated, nerve reaching to the point \ 

 capsule elongato-clavate, inclined. (TAB. XXX.)
