progress of cultivation^ and the alteration of roads, 
will also engage the researches of the practical 
botanist. Many plants have changed their localities, 
or have become entirely lost to us, even within our 
own recollection, by the circumstances adverted to. 
This will appear obvious on reference to the edition 
of Withering's Botanical Arrangement of British 
Plants, edited by Dr. Stokes,^ who formerly resided 
in Worcester, and who supplied Dr. Withering with 
the habitats of many Worcestershire plants. But 
many of these no longer occur in the places indicated 
by Dr. Stokes. We may instance the Sium latifo- 
Hum, no longer found "in the moors, near Pitch- 
croft the Apium graveolens, not now found in 
" Sansome fields," though abundant on the banks 
of the salt-water Droitwich canal ; and the Scandix 
Cerefolium, which till 1830 grew, as recorded by 
Dr. Stokes, " in considerable plenty in the hedge on 
the south-east side of the Bristol road, just beyond 
the turnpike," but the road-surveyors in altering the 
course of the Bristol road, having cut the bank away 
where the Scandix grew, not even a stray plant is 
now to be met with there. 
In Dr. Nash's History of Worcestershire, a cata- 
logue of Worcestershire plants is given, the only one 
of any account that had up to that time appeared ; 
but one plant is introduced there without sufficient 
authority, which should be expunged, as it has really 
no place in the Worcestershire Flora. This is the 
^ We have this edition in our Library. It is interesting, as many of Dr. Stokes's 
remarks are not embodied in succeeding editions.
