Mr. R. Spruce on the Musci and Hepatice 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 plicz, the mouth 
ciliate.

The characters quoted above from ‘ Hepaticze Pyrenaice’ 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 Labassére, on which Jg. sphero- 
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.
