BRYUM. 119 



4- 4- Leaves acuminate or acute. 

 Nerve of the leaf disappearing lelow the point. 



Br. crudum ; stems simple ; leaves rigid, lanceolate, the 

 upper ones the narrowest and longest, all of them plane, 

 serrulate, nerve disappearing below the summit ; capsule 

 oblongo-subpyriform, cernuous. (TAB. XXV1I1.)

Wahlenberg observes justly, that though the portions of 

 the stem above the earth appear perfectly simple, many of 

 them really arise from a common root. These stems have 

 a singular appearance; from the leaves, which become gra- 

 dually longer towards the extremity, and are of a shining 

 yellow green, not changing their direction when dry. Their 

 texture resembles that of the leaves of Br. nutans. 



9. Br. carneum ; stems simple ; leaves lanceolate, reticulated, 

 slightly serrulate at the point, nerve'disappearing below the 

 summit ; capsule obovate, pendulous. (TAB. XXIX.)

Stems short, rarely exceeding two or three lines, often 

 bearing innovations, and more frequently throwing up ste- 

 rile shoots from among the roots. The leaves want the 

 bright green colour of the congeners, and exhibit under the 

 microscope large reticulations. It is strange that Schwae- 

 grichen should refer for his Bryum erythrocarpum to Mohr, 

 who says only upon that plant " sub nomine Br. erythro~ 

 carpi, Brid. Suppl. MSS. etiam plantulam accepimus in 

 monte Hubc, prope Eibeck, a Bridelio lectam, quam a no- 

 stro (Br. earned) discernere nequimus." We on the other 

 hand have specimens perfectly agreeing with Schwaegri- 

 chen's figure of Br. erythrocarpum^ which we consider only 

 as slender varieties of Br. ccespiticium ; and that author 

 himself says, " ditfert a Br. ccespiticio caule tenero, foliorum 

 forma et nervo parum tantum emergence, colore theca3 

 nifo." 



Near to Br. carneum most authors place the Bryum an- 

 notinum (Mnium ) Linn.) of Hedvvig; a plaut, we regret
