The Sarnian, or Channel Island Flora, has been examined by Pro- 

 fessor 0. 0. Babington, and described in his Flora Sarnica. In gene- 

 ral the flora may be said to resemble more that of the coast of France 

 than that of the southern counties of England. Nearly all the species 

 appear to be natives of the north-western parts of France. Babing- 

 ton enumerates about 850 species of flowering plants and ferns as 

 occurring in the islands. Among the plants rare in England, or 

 specially characteristic of the Channel Islands, the following may be 

 mentioned : — 



Ranunculus ophioglossifolius. 

 Erucastrum incanum. 

 Sinapis Cheiranthus. 

 Matthiola sinuata. 



Helianthemuni polifolium. 

 Erodium mosohatum. 

 Hypericum linarifolium. 

 Anthrolobium ebracteatunL.
