Mr. R. Spruce on the Mttsci and Hepatica; of the Pijrenees. 287 



The scabrous seta:, the tristriate leaves, and the whole habit of this 

 species bring it so near /. sericeum, that in a natural distribution I 

 apprehend they must be placed in the same genus. Besides, if we 

 compare the fructification, w^e shall not find very great differences. 

 The capsule of /. bitesce?is (as above intimated) is sometimes elon- 

 gated and iwry nearly erect, although never quite symmetrical. The 

 inner peristome, as in /. sericeum and Philippianum, has the cilia either 

 ivholly or in part absorbed at the period of maturity, although capsules 

 not quite ripe show slender 2-3-nate cilia. (1 have observed similar 

 circumstances in /. polyanthum.) The chief difference from /. seri- 

 ceum is in the lacunose processes and their very slight granulation. 

 The annulus is double. The inner membrane of the capsule projects 

 beyond its mouth the breadth of the annulus before it is divided. 

 The teeth are strongly trabeculate within and enveloped in a delicate 

 membrane.
