The following phanerogams are additions to tlie Flora of 

 Guernsey, raising the total number recorded for the island to 

 796 species. When the name of a ])lant is enclosed in brackets 

 it signifies that the variety only is new. 



(Ranunculus aeris) var. Steveni, Amli-z. Grande Marc. 



(R. aeris) var. Boraeauus, Jord. Grande Mare. 



Linum usitatiSSimum, X. One plant on the roadside near the Vale 



School. Mr. Druce mforms me that in Babington's Herbarium at 



Cambridge, there is a specimen of the var. crepitans gathered in Guernsey 



in 1837.

Some years have now elapsed since any systematic work 

 was done at the seaweeds ; but there are a few^ novelties to be 

 recorded. One of the most interesting is Codium Bursa, a 

 curious alga Avhich very much resembles a dark green sponge. 

 Last winter I was fortunate enough to find a fine fresh 

 specimen about five inches long, and somew^hat pear-shaped, 

 which had been waslied up on the beach at Petit Port. 

 Curiously enough, a fortnight afterwards my little son found a 

 second specimen cast up in Moulin Huet Bay. Codium 

 Bursa is an extremely rare seaw^eed in the British Isles. 



In Mr. E. A. L. Batters' Catalogue of British Marine 

 Alg(B (1902) several species are noted for Guernsey which 

 have not been included in our lists, so I take this opportunity 

 of recording them now. In some cases the type is already on 

 record, but the variety is new to the island. 



Hyella eaespitosa, Bom. Guernsey (Bat. Cat.). 

 MastigoeoleUS testaPUm, Lager. Guernsey (Bat. Cat.). 

 (EntePOmOPpha elathpata), var. gracilis, Lejol. Guernsey (Bat Cat.). 

 Codium Bupsa, Ag. One specimen washed up at Petit Port, and another 

 at Moulin Huet Bay, both in December, 1905.
