HEPATICiE. 



The list of Hepatics given in the Flora bears witness to the 

 well-known thoroughness of Mr. Linton's work. His general 

 remarks on distribution are fully confirmed by our observations. 

 The Millstone Grit and the grits of the Yoredale Series are by far 

 the most productive in Hepatics. 



Of the fourteen species and varieties mentioned by Mr. Linton 



>und on the Limestone alone, only one has been found else- 

 where by us — on the Coal Measures and the Grit. Of the twenty- 

 eight given in the Flora for Grit alone we have found one on the 

 Permian, two on the Coal Measures, one on the Carboniferous 

 Limestone, and four on the Yoredales. It must be remembered, 

 however, that Mr. Linton included some Yoredale districts under 

 (Lj and others under (G). 



A noticeable feature of the Hepatics during the wet summer 

 of 1912 was the green colour of the plants of many species 

 which are usually red or purple.
