ALDERNEY. 



The most iDterestino- plant added to the Alderney Flora 

 by Mr. Druce is Ac/rostis rertici/lata, a. very handsonie grass 

 unknown in Britain, as I have already mentioned. Its occur- 

 rence there as well as in Guernsey supports the belief that in 

 these islands this plant is not a mere colonist, but a true native, 

 like Ophioglos.s/fm lf/..sitauicf/nt and Tsoeies hystrix, which also 

 belong to the flora of Southern Europe, although certainly 

 indigenous here. Seven other ncAv species were found by 

 Mr. Druce, and a new^ named variety, all of which have been 

 noted in Guernsey. The phanerogamic Flora of Alderney is 

 thus raised to 524 species. 



Melilotus alba, Lam. 

 Rubus leueostaehys, Schi. 

 R. eopylifolius, Sm. 

 Chenopodium opulifolium, Schrad. 

 Agpostis vertieillata, Viii. 

 Festuea ambigua, Le Gall. 

 Bpomus eommutatus, Schrad. 



B. hOPdeaeeUS, var. Thominii, Brch. 

 (Tpitieum Pepens) var. barbatum, I)av. 



SARK. 



Five Flowering Plants not hitherto recorded for Sark 

 have to be added to the list, four of them found by Mr. 

 Druce, and one by Mr. Derrick. Like several other botanists 

 who have visited Sark of late years, Mr. Druce kept a sharp 

 look-out for various species of Medicago^ but failed to discover 

 a trace of any of them. I think Ave may now safely conclude 

 that the entire genus is absent, which is indeed most remark- 

 able, considering how common M. lvq)u.Hn(i and M. rndctthtta 

 are in every one of the other Channel [slands, except Brechou
