192 FLORA OF JERSEY. 



plants of this group have been able to attain. They have 

 travelled up the coast of France so far, but been unable to cross 

 the Channel. They are Gymnogramme leptophylla (Jersey and 

 perhaps Guernsey), Ophioglossum lusitanicum (Guernsey), Isoetes 

 Hystrix (Guernsey), Phalaris minor Eetz. (if native in Guernsey), 

 Milium scabrum Merl. (Guernsey), Lagarus ovatus (Guernsey), 

 Bromus maximus (Jersey and Normandy), Dianthus gallicus 

 (Jersey), Eanunculus ohaerophyllus L. (Jersey), Ononis reolinata 

 (Guernsey and Alderney : alien in S. Scotland), Ornithopus ebrac- 

 teatus (Guernsey, Alderney, and Scilly Islands), Statice lychnidi- 

 folia (Alderney), Armeria plantaginea (Jersey and Normandy), 

 Cicendia pusilla (Guernsey and Normandy), Echium plantagineum 

 (Jersey), Centaurea aspera (Jersey). 



IV. Relation of the Channel Islands Flora to that or the 

 Neighbouring Parts of France. 



All the Channel Islands plants occur in either Normandy or 

 Brittany with the exception of Hypochteris maculata (Jersey), the 

 newly discovered Milium scabrum (Guernsey), Echium plan- 

 tagineum (Jersey), and perhaps Centaurea aspera, which appears 

 to be possibly native in Jersey, but is introduced in both Nor- 

 mandy and Bi'ittany. With these three exceptions the whole 

 Channel Islands Flora reappears in Brittany, but there are 

 several plants, all belonging to the S. European group, which are 

 not found in Normandy. They are Gymnogramme leptophylla, 

 Adiantum Capillus- Veneris, Ophioglossunr lusitanicum, Isoetes 

 Hystrix, Dianthus gallicus, Ononis reclinata, Ornithopus ebrac- 

 teatus, and Linaria Pelisseriana. This fact seems to indicate that 

 the southern species have reached the Channel Islands by some 

 land connection existing in former times with the coast of 

 Brittany. 



V. Naturalised Aliens and Casuals. 



Thanks to the mildness of the winters and the large number of 

 hours of sunshine, there are many interesting Naturalised Aliens 

 in the Channel Islands, some of ■\\liich could not possibly be dis- 

 tinguished from the native flora apart from a knowledge of their 

 origin. I will mention some of the more remarkable.
