plants, adds much to the value of the book. Mr. Baines’s list of 
species, and of the stations of the rarer ones, is no doubt still imper- 
fect; but its publication, such as it is, will be a great help to the 
cultivators of botany within the district, and not less important to 
those in other parts who want to know where the rarer species may 
be procured, or who study the geographical distribution of plants 
over the country, and the connexion of particular species with par- 
ticular rocks, soils, or local circumstances. 
On these points the information given is no doubt accurate ; but 
conclusions drawn from the mere circumstance of species not having 
been noticed in particular districts are seldom to be relied upon until 
the statements have been some time before the public without being 
called in question. For example, Rosa rubiginosa is quoted by Pro- 
fessor Phillips in the introductory essay as confined in Yorkshire to 
the north-eastern or oolitic hills, but a supplement to the work re- 
turns it as occurring at Conisbro’ in the south-western distriet, and 
we have ourselves found it truly wild within a few miles of York, 
in the great central vale. Speaking of this latter district, Professor 
Phillips remarks, ‘‘ that receiving from numerous streams the de- 
tritus of the uplands lying east and west, the vale of York is full of 
plants which seem derived from these districts, as well as others more 
commonly found in lower ground. Its flora is consequently very 
rich, and plants supposed to characterize different soils grow here 
near together.” It is, indeed, very striking to see in low moist fields 
over this plain plants usually stated to be peculiar to limestone or 
chalk, and to see them here attaining a magnitude and luxuriance, 
which they seldom approach in their more appropriate stations ; but 
the soil will be found everywhere to abound with lime, so that the 
fact confirms the opinion (could it be supposed to need any confir- 
mation) that certain plants require the presence of this substance for 
their healthful growth. Campanula glomerata, Orchis ustulata, 
which attains to remarkable size and beauty, and Poterium Sangut- 
sorba, here growing abundantly in moist fields subject to frequent 
overflows, (though only mentioned by Mr. Baines as appearing on 
limestone rocks and the chalk wolds) are instances of proper lime- 
stone plants which abound in this district. 
When Professor Phillips speaks in his essay of Dryas octopetala 
as peculiar to Yorkshire, he, of course, means in England, which 
should have been expressed, as most floras include plants of Scot- 
land and Ireland, and the Dryas occurs in both countries. Even 
with respect to England, the statement is not strictly accurate, as 
Mr. Harriman found it in Durham. 
Arabis hispida (petrea of DeCandolle) can only be said to be pe- 
culiar to Yorkshire, speaking of England, exclusively of Wales as 
well as Scotland, and Juncus polycephalus belongs to the highlands 
of Scotland. The presence of these plants shows that Yorkshire has 
a more alpine character than any other district of England, not even 
excepting the Cumberland and Westmoreland mountains. 
Among the plants which attain their southern limit in Yorkshire 
is mentioned Sazifraga umbrosa. This plant, in fact, is hardly found 
in England, except in Yorkshire ; but it is not a northern plant, the
