MOSSES AND HEPATICS OF ASKRIGQ AND DISTRICT. 



WM. INGHAM, B.A., 



York. ■ , 



This district is particularly rich in these plants. Some years 

 ago Mr. R. Barnes, of Harrogate, carefully worked this part of 

 the botanical Vice-county 65 and discovered a good number of 

 our rarest British mosses. On the occasion of the recent visit 

 of the Yorkshire Naturalists' Union it was interesting to con- 

 firm some of Mr. Barnes' discoveries and add other rare and 

 interesting mosses and hepatics. 



It will be convenient to arrange the plants according to the 

 routes traversed and to indicate Mr. Barnes' original discoveries 

 by the letters R. B.
