The only botanist who appears to have well understood the 

 three preceding species of Andrcea was the late Dr. Mohr, who 

 first described A. Roihii as distinct from rupestris, and gave 

 fifTures of them all in his excellent JVar« Germafiica. A. Rothii is 

 far from uncommon in the mountainous parts of the British 

 isles, and is immediately distinguished by its very black colour 

 and small size. It is unquestionably the plant intended by the 

 name of A. rupestris in the Muscologia Hibernica, which caused 

 Hedwig's figure of the true ^. rupestris to be there referred to 

 J. aZprwfl, thougli its most striking character, the midrib of the 

 leaves, is not noticed by Mr. Turner. In the neighbourhood of 

 Bantry it is so abundant, that, according to Miss Hutchins, the 

 mountains are black with it.
