of the Channel Islands. 349 



taken, in Guernsey. Mr. W. Wilson Sanders informs me that he has 

 gathered it in ditches at Ham Ponds, near Sandwich, Kent. 



Carex punctata. In wet marshes, in Guernsey. This plant has 

 been submitted to the inspection of Dr. Boott, from whom a mono- 

 graph on this difficult genus is shortly expected, and he has conferred 

 the name*. It has, I believe, been noticed in several parts of En- 

 gland. 



The following additional species have been gathered in these 

 islands, but not in Britain. 



Neottia cestivalis, in Jersey. 



Sinapis incana, in Jersey. Noticed this summsr plentifully in 

 Alderney. 



Mercurialis ambigua, in Jersey. This appears to be only a variety 

 of M. annua, but is probably the plant of the younger Linnaeus. 



Atriplex rosea. Jersey and Guernsey. I believe that this will be 

 found to exist upon the south coast of England. 



Arthrolobium ebracteatum, in Guernsey. During the present year 

 I have found this plant in plenty in Alderney. 



These five were first gathered by myself ; the following had been 

 noticed by other botanists previously to my visit. 



Allium sphaerocephalon. Armeria plantaginea. 



Bromus maximus. Echium violaceum. 



Festuca sabulicola. Centaurea Isnardi. 



Brassica Cheiranthus. Lagurus ovatus. 



Scirpus pungens. Juncus capitatus. 



The total number of flowering plants and ferns which have been no- 

 ticed in the islands amounts to above 760, of which 20 have not as 

 yet been gathered in Britain. Alderney and Sark have been less care- 

 fully examined than Jersey and Guernsey, as I was not able to de- 

 vote more than a week to each of them, and very little has been 

 done by other botanists. The number of plants which I observed in 

 Alderney is about 330, and in Sark 252 ; the little island of Jethon 

 supplied me with 115 species, and an adjoining conical rock, called 

 Crevichon, is inhabited by 22 species, nearly the whole herbage con- 

 sisting of Silene maritima. 



In conclusion I may be allowed to mention that I am about to 

 publish an outline of the Flora of the islands, under the name of 

 ' Primitise Florse Sarnicse,' and shall be much obliged to any bota- 

 nist who may favour me with information on the subject. 



Since this paper was read at Newcastle I have learned that Ar- 

 throlobium ebracteatum has been discovered (in April 1838) in abun- 



* Is there not a Carex punctata, Gaud. ? (457 Reich. Flor. Excurs.) — Edit.
