HEPATICAE {Liverworts) 



The county of Devon is peculiarly adapted for the growth of these 

 moisture-loving plants, the stony streams and sheltered ravines of 

 Dartmoor affording many species that are absent in less favoured counties. 

 The number of species represented in the county amount to about half 

 of those known to occur in Great Britain and Ireland. Those which 

 are absent are chiefly of a northern character or which usually grow at 

 an elevation of over 2,000 ft. Several also that occur on sandstone rocks in 

 other counties do not occur on the less porous granite of Devon. The 

 number of Hepaticae recorded from Devon exceeds that of Cornwall by 

 twenty-five species, which are chiefly of such as occur on the higher parts 

 of Dartmoor. But on the other hand Cornwall is richer in recorded 

 species oi Riccia, the following not having yet been detected in Devon, 

 viz., Riccia bifurca, R. ciliifera, R. glaucescens, R. sorocarpa and R. tumida. 

 On Braunton Burrows however, Riccia crystallina, which is not recorded 

 for Cornwall, forms a marked feature of the dried-up ponds in the
