character. Indeed the well-known student of the genus, Dr. Roniger, 

 who has specialised on this group, considers it to be identical with the 

 plant he has recently described as a sub -species M. paradoxxim. Mr. 

 Lumb has recently directed my attention to a note by Dawson Turner, 

 who, writing of some woods near Crummock Water in Cumberland, says 

 *' When I was in this county in 1796 I remarked two very remarkable 

 and apparently distinct varieties of M. pratense, one with deep yellow, 

 the other with very pale flowers ; but I have unfortunately omitted to 

 note down the differences, and I have since lost my specimens, so I can 

 only request the attention of other botanists to this matter." There 

 is no doubt that the yellow-flowered plants were my var. hians, which 

 I have seen in the vicinity.
