Mr. Charles Bailey on 



Arenaria gothica {E. Fries) as a plant new to Britain. 

 By Charles Bailey, F.L.S. 



{Received October 15th, iSSp.) 



The specimens of Arenaria gothica, Fries, now sub- 

 mitted to the members, as representing a recent addition 

 to the flora of Great Britain, were collected at Ribblehead, 

 Yorkshire, in September last, by one of our honorary mem- 

 bers, Mr. J. G. Baker, F.R.S., F.L.S., of Kew, the locality 

 having been first discovered by Mr. Lister Rotheray, a 

 Skipton botanist. Its occurrence in Britain is noteworthy 

 from the side of phytogeography, and it is very difficult to 

 explain why it has not been met with previously, as the 

 district round Ingleborough is classic botanical ground. 



So far as has been recorded the typical Arenaria gothica 

 is restricted to two Swedish localities, viz., to Kinnekulle 

 mountain, in the province of Skarabog to the south of Lake 

 Wener, and to the island of Gothland, chiefly in the neigh- 

 bourhood of Wisby. Sheets of specimens from my herba- 

 rium are shown for comparison ; from Kinnekulle, collected 

 by Lindgren, J. Bergmann (July, 1850), F. Ahlberg (27th 

 June, 1862, and July, 1870), A. Andre (July, 1871), C. O. 

 Schlyter (25th June, 1875), and C. J. Johanson (18th July, 

 1878); and from Wisby, collected by P. F. Lundquist (July, 

 1883), and O. Olsson (9th July, 1883). The same species, 

 or some geographical form of it, occurs at the edge of the 

 Lac de Joux, 3,310 feet above the sea, and at the feet of two 

 of the highest mountains of the Jurassic Chain, — Mont 

 Tendre, and Dent-de-Vaulion ; in C.-M. Philibert Babey's 

 "Flore Jurassienne" (1846), Vol. I., p. 255, this Lac de 

 Joux plant is considered to be Arenaria multi-flora, Koch ; 

 in Grenier and Godron's " Flore de France" (1848), Vol. I.,
