nearest portion of the continental mainland, and at least half a dozen 
occur in the neighbouring island of Jersey :— 
Anemone nemorosa. Lactuca muralis. 
Caltha palustris. Campanula rotundifolia. 
Stellaria Holostea. Vaccinium Myrtillus. 
Oxalis Acetosella. Erica tetralix. 
Orobus tuberosus. Melampyrum pratense. 
Angelica sylvestris. Lamium album. 
Valeriana officinalis. Lysimachia vulgaris. 
Solidago Virga-aurea. Mercurialis perennis. 
And the list might easily be extended Some of these are woodland 
species, it is true, but it must be remembered that Guernsey was 
once well wooded, even within historic times. 
In all descriptive works dealing with the flora of Britain, as well 
as in the various editions of the London Catalogue of British Plants, 
it has been customary to distinguish in some way those particular 
species which are confined to the Channel Islands; that is to say, 
continental plants indigenous to the group, but unknown on the 
north side of the English Channel. This is a convenient arrange- 
ment. since it recognises their existence within the limits of the 
United Kingdom, without including them in the flora of Britain 
proper. About twenty of these Channel Island plants are enumerated 
in the last (1895) edition of the London Catalogue: some of them 
are peculiar to Jersey, some to Guernsey, one or two to Alderney, 
and some occur in two or in all three of these islands. Out of the 
seventeen non-British species found in Guernsey, six are confined to 
that island exclusively. Various attempts have been made from 
time to time by foolish persons to introduce into the other islands 
some of these local plants, but happily such attempts have for the 
most part proved abortive. The non-British Guernsey plants 
(omitting Casuals which are not permanent in their stations) are the 
following :— 
Brassica Cheiranthus. Phalaris minor. 
Sinapis incana. Milium scabrum. 
Viola nana. Lagurus ovatus. 
Silene quinquevulnera. Cynosurus echinatus. 
Gnaphalium luteo-album. Bromus maximus. 
Centaurea aspera. Gymnogramme leptophylla. 
Cicendia pusilla Ophioglossum lusitanicum. 
Orchis laxiflora. Isoetes Hystrix. 
Allium Ampeloprasum. 
Now it is well to notice that these seventeen plants are by no 
means common on the adjacent French coast. On the contrary, a 
reference to Corbiere’s Vouvelle Flore de Normandie (1894) will 
show that not a single one occurs there plentifully ; several are very
