THE FLORA OF WENSLEYDALE, 

 NORTH-WEST YORKSHIRE. 



JOHN PERCIVAL, B.A., 

 S^. Johns College, Cambridge. 



Wensleydale is situated in the north-west division of Yorkshire. 

 The district over which my observations have extended includes the 

 main valley of the Yore, between Hawes and Leyburn, together 

 with the smaller valleys which join it between those limits. The 

 chief rocks met with in the district are limestones belonging to the 

 Yoredale series. Small bands of grit occur in the series, but mill- 

 stone grit only occurs in isolated patches on the highest points, as 

 Penhill, 'Grits' above Carperby, and Stags Fell near the head of the 

 dale. 



The altitudinal range of the district is between about 350 ft. and 

 2,000 ft. — the river-bed at Leyburn being about 350-400 ft., and 

 the summit of Penhill about 2,000 ft. above sea-level. The fruticose 

 Rubi are, of course, poorly represented. 



I have to thank Mr. F. Arnold Lees for kindly supplying a good 

 many stations referring to the upper part of the dale, and also 

 Mr. J. G. Baker, F.R.S., for kindly examining the Ros^.
