specimen of the Erysimwm orientale in my herbarium gathered on 
the sea-cliff at Sheringham, near Cromer, so far back as 1829, and 
a few other localites are given for it (chiefly in the eastern 
counties) in Smith’s English Flora, though not mentioned in 
Trimmer’s Flora of Norfolk. Here then we have nearly the 
whole breadth of England lying between the eastern and 
western stations for this plant ;* which taken in connection 
with the strife and struggle our plants have had to sustain 
over long periods of time, from one or more of the causes 
spoken of above, we cannot wonder at any anomalies that 
Occur in respect of the situations in which:we now find 
them, or say how long they may have been hid from view, yet 
with the living principle still in them, ready for development at 
any time, the surrounding conditions being favourable. 
While in the case of some species, as in that last noticed, the 
localities in which they occur are widely apart, other plants have 
been driven up into corners, and become so extremely rare as to 
be on the verge of extinction altogether. I have heard that the 
beautiful Lady’s Slipper, Cypripedinm Calceolus, is now confined to 
a single wood in Yorkshire, in which it is strictly preserved, as 
quite right it should be, by the owner of the property. I myself 
am fortunate in possessing fine specimens of two other plants 
which are extremely rare, if indeed they still exist. One of these 
is Orchis hircina, which was given to me more than half-a-century 
ago by a botanist in the neighbourhood of Dartford in Kent, 
where I was visiting, and who told me he had gathered it in a 
wood near his house, where he did not think it was any longer to 
be found. The other plant alluded to above is the Senecio 
paludosus, a fen plant almost extirpated by drainage. It was not 
drainage, however, which destroyed the locality in which I 
obtained my specimens. The circumstances were as follows. A
