NOTES ON THE FLORA OF THE CHANNEL ISLANDS 397 



the same species. There is more than one would at first suspect 

 that recalls the flora of South Devon and Cornwall. There is 

 also the interesting evidence of a Peninsular, and indeed of a 

 Mediterranean, element ; as Mr. Lester-Garland says : " It was to 

 be expected, a pr%ofi % that the mildness of the maritime climate of 

 Western Europe would enable some of the southern plants to 

 advance much further north than is possible in the interior of the 

 Continent, and experience has proved that this expectation has 

 been justified." He enumerated twenty-six species "whose proper 

 home is on the shores of the Mediterranean and which straggle 

 up the west coast of France, becoming rarer as they advance 

 towards the north." Of these Mediterranean species, fourteen 

 are not found in Britain. To those enumerated I am now enabled 

 to add three species, two of which are almost certainly native 

 elements of the island flora — Spergidaria atheniensis, which has a 

 wide range along the Mediterranean coast, and Orobanche Ritro 

 var. hypocharoides, the type of which is limited to a few localities 

 north of Marseilles, but here exists as an endemic variety on a 

 different host-plant. Agrostis verticillacantha, which is abundant 

 in Guernsey, may not be native, since it is said to be introduced 

 in its only known station in north-western France in the environs 

 of Cherbourg, but further research may establish its claims to a 

 higher grade of citizenship. Besides these distinct species, we 

 have a well-marked modification of Picris hieracioides in Aldernev, 

 of Leontodon nudicaulis in Guernsey and Alderney, of Vicia angus- 

 ti folia in Jersey, and of Spergula arvensis in Guernsey, Jersey, 

 and probably Alderney. Nor must the peculiar Salvia, which I 

 have named Marquandii, from Guernsey be forgotten in this 

 enumeration of the more striking features of the Channel Island 

 Flora. 



One of the joys of my visits (for since I wrote the foregoing 

 I have, in the spring of 1907, again been to the islands in order 

 to see Ophioglossum lusitanicum and Ranunculus flabellatus) was 

 to meet with the veteran Mr. Piquet, now considerably over 

 eighty, and to find him active and vigorous, and botanically as 

 keen as ever. To him, to his son, to Mr. Lester-Garland, and 

 Mr. E. D. Marquand my best thanks are due for their great 

 kindness. 



The following is a list of the more interesting forms noticed in 

 localities which are mainly additional to those given in the pub- 

 lished Floras. The sign f means an addition to the island. 



Ranunculus sceleratus L. Rare in Guernsey; I saw it at 

 Perelle Bay. — R. Flammula L. Not uncommon and variable. 

 The large form, var. serratus Pers., grew near St. Ouen's Pond, 

 Jersey, and in the Grande Mare, Guernsey. On the damp spots 

 on L'Ancresse Common R. Flammula occurred as a diminutive 

 form with the facies of R. reptans L., but it was not creeping. In 

 the damp gully near Grosnez, Jersey, it occurred as a small stout 

 form. — R. Lingua L. still occurs in the pond on Longy Common, 

 Alderney, the only locality in the Channel Isles. — \R. Steveni
