From the above records it will be seen the head-quarters of this 
species in England is Norfolk ; no less than thirty-three stations 
being now on record. This is quite as much so as to stations, as to 
numbers of specimens. The only county at the present time in 
which it exists in any quantity outside Norfolk is Suffolk. And 
I have little doubt that these numbers in Norfolk would be 
largely increased if looked for ; wherever I have searched marshy 
ground I have found it, though sometimes in very small quantity. 
Mr. Winter (Phyt. 227, 1863) speaks of its abundance at Ranworth 
by saying “ One might gather waggon-loads of it.” I have never 
seen it in such quantities as this would imply, but it is abundant 
at Rollesby Broad. The finest specimens I have seen were at a 
dyke-side in Filby Broad, and were six feet high, with branches in 
proportion, and fine umbels. 
There is however no doubt that before the systematic drainage of 
the Fens, Marshes, Carrs, &c. began, it was plentiful in many 
counties, but until Mr. II. C. Watson began his series of works 
(1832), little trouble was taken to record localities in any systematic 
manner, hence our records are very meagre, though I believe that 
closer searching among old books and herberia might afford more 
data that at present we possess. The Caterpillar of the Swallow- 
tailed Butterfly not only feeds on this plant, but also on Angelica 
sylvestris, as I observed it doing so in 1900, at Thurne and Ranworth.
