Note by Mr. Aethur Bennett, F.L.S., on the Specimens of Plants 

 gathered in Iceland in 1889, exhibited by the Rev. Dr. 

 "Walker, 21st November, 1889. 



The collection made by Dr. Walker consisted of about 82 

 species, gathered in various parts of the south-west, west, north, 

 and north-east of the island. The species of interest were : — 

 Silene inflata : this was recorded by four of the authors who have 

 written on the flora, but not accepted by Groenlund in his ' Flora ' 

 (1881) ; there is only a scrap, but sufficient to determine tlie 

 species. Alchemilla fissa, Schum., Yva\faroensis, Lange ; this has 

 been recorded by Stromfelt (Stockholm Trans.) as A. conjuncta, 

 Bab., which it certainly is not. Clilora perfoliata, L., and Erytlircea 

 Centaurimn, L. : these can hardly be anything but introductions, 

 their geographical limit is entirely against their being indigenous 

 species. Plantago Coronopus, L. : this lias only been recorded by 

 Carrol ( Jouru. of Botany, 1870, p. 356) ; a single scrap is all I find 

 among Dr. Walker's specimens. Polygonum avicidare, Liun.,var. 

 littorale: clearly this form, but only a single specimen. Orchis 

 Jatifolia, L., var. : a second station for the island, the first specimen 

 having been gathered by Miss Thora Fridriksson. A small form of 

 Daucus CV/ro^ff, Linn., was gathered at Eskifjordr ; this has not 

 been recorded for the island, and is a considerable extension of 

 its known northern limit in Europe.
