and doubtless others will yet be added to the list, for it cannot be 
questioned, I think, that a constant redistribution is going on locally 
and generally, so that in a number of years rare plants may become 
commoner and common ones scarcer. The watching of such redis- 
tribution is one of the pleasures of the botanist and I should say 
not the least one. | 
I may mention that the nomenclature which I have followed is 
that of Hooker’s Students’ Flora. 
[Nore—Dec., 1881.—Of the two following plants the first was 
overlooked in the preparation of my paper and the second was found 
_ after the paper had been read before the Society. 
Claytonia alsinoides, which seems to have become naturalized in 
many places, is found in a small wood between Ashton and the 
Cloch, where it has by some means been introduced. It has re- 
tained its hold here for many years, and judging by its luxuriance 
it appears to find the conditions very suitable. Very probably this 
species will, ere long, have to be included amongst British plants, 
C. perfoliata having been already admitted. 
A specimen of a new introduction, Salvia verbenaca, has been 
shown me by Dr. J. K. Robertson, of Greenock, who found it this 
summer, 1881, in a field near where the Clyde Floating Baths were 
moored. I have since gathered other specimens at the same place. 
This plant has hitherto only been found on the East Coast at Salis- 
bury Crags, and in Fifeshire from Burntisland eastwards. |
