FLORA OF YORKSHIRE. 21 
ginosa, Salix acutifolia, and Carex paradozxa, to which Saxifraga 
umbrosa may be added. 
Three local species are not known to grow in any of the east- 
ern counties, either to the north or the south of Yorkshire, viz. 
Actea spicata, Asarum Europeum, Lastrea rigida. 80 species 
have their boreal or northern limit in Yorkshire, and 50 species 
have their southern limit in this county. See Sup. p. 16. 
About thirty pages are occupied with an outline of the bear- 
ings of the physical geography of the county upon its vegeta- 
tion; a statement of much interest to those who study vege- 
tation in connection with geological formations, river-basins, 
ete. But we beg to refer our readers to the work itself, in 
which they will find satisfactory information on these heads. 
We wish the editors or authors of the ‘ Supplement’ had pre- 
pared a new edition of the ‘ Flora,’ rather than a supplement to 
the former. The reasons for this desire are obvious enough. 
We do not find fault with them for this: they only intended to 
publish a supplement, and they have done so, as far as we can 
judge, very carefully. It is a complete Flora of the county, and 
will, for most purposes, supersede the use of the original work. 
But the reader will desire information about the localities of the 
rarer piants of the Flora, and generally he will find in the ‘ Sup- 
plement’ only the name, etc., except where new localities have 
been discovered ; hence he finds it necessary to possess and con- 
sult the original work. We should also have wished a complete 
map of the county, viz. the East and West Ridings, as well as the 
North. There are obvious reasons also for this; though we have 
no right to blame the authors for not consulting our desires and 
necessities. We thankfully take what they have given, and hope 
it may be only an instalment of what they can and will do for the 
promotion of local botany. 
The number of Mosses named and localized in the ‘ Supple- 
ment’ is 40 genera and 323 species. In the name of the readers 
of the ‘ Phytologist,’ we thank the gentlemen who have supplied 
us with a complete Flora of the largest county in England, and 
which perhaps yields more species interesting to botanists than 
any other county in Britain. Its northern portion is nearly mid- 
way between the northern and southern extremities of the island ; 
and of the eastern counties of England, it possesses the greatest 
variety both of soil and elevation. Its Flora is intermediate be- 
tween the austral and boreal type of distribution; it is a lnk
