We have then for Iceland, of plants not British, 62 species and 

 30 varieties ; or, rigidly excluding all doubtful forms, the numbers 

 will be 52 species and 30 varieties. 



For the Faroes we have of plants not British 20 species and 39 

 varieties ; or, again rigidly excluding doubtful plants, 13 species 

 and 39 varieties. 



For Iceland these numbers may be compared with Professor 

 Babington's " Revision," where he gives 62 species as not British ; 

 but he includes among these Sedum villosum L., and Draba 

 muralis D. C, both of which are British. Taking his figures it 

 would seem that I was not justified in my remark respecting the large 

 proportion of doubtful plants ; but it must be remembered that I 

 have excluded from my list many species reported by one or other 

 of the writers on Icelandic botany, from Kcenig and Rottbcell to 

 the present time, else it would have been much larger. 



NOTES ON BEITISH CLADONIJE. 



By Dr. JAMES STIRTON, F.L.S. 



TO Mr. James M 'Andrew of New Galloway, I am almost en- 

 tirely indebted for the materials whereby I have been 

 enabled to make the following observations on the Scottish 

 Cladonise. 



Within the last two years he has sent me upwards of 250 

 specimens, many of which are in fine condition, inasmuch as he 

 has followed out his researches at all seasons, and has thus been 

 enabled to select specimens in perfect condition. The interests 

 of botany would be largely enhanced if there were a few such in- 

 defatigable botanists as Mr M'Andrew scattered over Scotland. 



The district of which New Galloway may be said to be the 

 centre is peculiarly rich in Cladoniae. The country is open, and 

 diversified by hill and dale and loch, while the woods properly so 

 called are detached, as well as in various stages of growth. Much
