Mr. R. Spruce on the Musci and Hepatica of the Pyrenees. 107 



The fructification in my specimens differs somewhat from the de- 

 scription in ■ Synopsis Hepaticarum '; it is as follows : — Involucral 

 leaves with very acute segments, otherwise not differing from the 

 cauline ones, with the exception of the innermost, which is rather 

 shorter and terminated by several unequal apiculate teeth : it is ac- 

 companied by a lanceolate very acute stipule. Perianth oblongo- 

 cylindrical, compressed, with four obtuse angles or plicae, the mouth 

 ciliate.

The characters quoted above from ' Hepaticse Pyrenaicae ' correctly 

 indicate the differences of this plant from Jg. crenulata, and I am 

 now quite satisfied of their being specific.

The black crumbling schist at Labassere, on which Jg. spharo 

 carpa and hyalina occur intermixed, is precisely of the same nature 

 as the alum-shale in Eskdale near Whitby, Yorkshire, and it is re 

 markable that there also the same two species grow together in con 

 siderable quantity.
