As the districts stand at present, Carex ovalis is an addition to 

 District 6, but I prefer to include it in District 2. 



There are three tolerably distinct forms of Saxifraga hypnoides to 

 be met with on the Galtee range. Following the names given in 

 Syme's English Botany, these seem to be S. hirta, var. genuina and var. 

 affinis and S. eu-hypnoides, var. platypetala. All may be met with in 

 various parts of this range, and to a considerable extent, irrespectively 

 of altitude ; but S. affinis is the form usually to be found at the greatest 

 heights : S. platypetala in the wetter and mossy places by streams 

 at lower levels ; while >S'. Mrta, var. genuina, the finest- cut form with 

 bristle-pointed leaves, is especially characteristic of the bases of the 

 loftier cliffs, as at Lough Muskry. S. Mrta of the Galtees is much less 

 hairy than the Donegal plant found by me on Aranmore ; ^ but in other 

 respects they are, I believe, identical. 



My experience of these Irish Saxifrages and of the innumerable 

 arctic forms of S. ccespitosa leads me to believe that an unbroken 

 chain from the extreme forms of 8. hypnoides to those of S. ccespitosa 

 might be enumerated which would defy division. But it is unfor- 

 tunately necessary to have names for forms belonging to different 

 countries. 



In conclusion, I have to acknowledge my obligations to Mr. Back- 

 house, who kindly examined some Saxifrages and Hieracia ; and to my 

 friend Mr. A. Gr. More, who has, as usvial, afforded me every assistance 

 in his power. 



General list of the Plants observed on the Galtee mountains, ar-

 the convenience of comparison with other mountain ranges. Special
