Art. LXXII. — List of Jungermanniee S^c. observed in the neigh- 

 bourhood of Dumfries. By James Cruickshank, Esq. 



The neighbourhood of Dumfries appears particularly favourable to 

 the growth of Cryptogamic plants, especially mosses and Hepaticae, 

 as may at once be seen both from the number of species and the size 

 and beauty of the specimens. 



The extensive tracts of uncultivated mossy ground on the Dumfries 

 side of the Nith, and the long range of green pasture hills on the op- 

 posite side of the river in Kirkcudbrightshire, intersected as they are 

 by deep rocky glens, and in some parts covered with extensive woods, 

 are all favourable to the growth of these orders. 



T have for the last two years paid particular attention to the mosses 

 and HepaticEe, and have succeeded in collecting a good number of 

 species of each. I subjoin a list of the Hepaticae, with their locali- 

 ties, and, so far as I can judge fi-om my opportunities for observation, 

 the frequency of their occurrence throughout the district.
