V. NOTES AND CORRECTIONS. 
This volume has been printed in three separated Parts, dated 
in 1868, 1869, 1870; the several Parts having been written 
chiefly in the years preceding those dates. Some additional 
information has been obtained during the years named. The 
Clydesdale Flora, by Roger Hennedy, a well written and 
apparently a very reliable work, remained entirely unknown to 
me, while writing the First and Second Parts. And as my 
information about the botany of the western provinces of Scotland 
was incomplete, mostly old, and not quite reliable in many cases, 
the Clydesdale Flora has been since found a most useful 
acquisition. The Second Edition, dated in 1869, the one quoted 
from in the following pages, enables me to add provinces 13 or 16 
to the areas of various plants, which before had not been ascer- 
tained to occur in the West Lowland or West Highland 
provinces; two of those in regard to which our floral lists might 
be deemed least completed. And I have been usefully aided in 
like manner for the same provinces by manuscript notes kindly 
sent by Mr. Galt of Glasgow. 
Mr. Archer Briggs, a resident of Plymouth, has kindly com- 
municated various acceptable facts about the plants of the 
Peninsula, and the extension into Cornwall of some species not 
before ascertained for that most westerly county of England. And 
Mr. A. G. More has also most obligingly gone over the two Parts, 
in order to test the accuracy of the usual citation of “ Wight” 
in the series of southern counties; pointing out some needed 
corrections, which his own more thorough knowledge of the island 
botany enabled him to make.
