184 The Scottish Naturalist. 



For some of the following particulars regarding the synonymy and 

 distribution I am indebted to Mr. Bennett 



Juncus alpiims, Villars (1787); /. fusco-ater, Schreber 

 (18 n); J. ustulatus, Hoppe ; J. noriulosus, Wahl. ; J. 

 geniculates, Schranck. ; J. alpestris, Hartm.; J. rariflorus y 

 Hartm. ; J. pelocarpus, A. Gray. 



Several varieties have also been described, from which fact, in 

 addition to the synonymy, it may be gathered that Juncus alpinus 

 has a considerable range of variation. Dr. Buchenau, to whom Mr. 

 Bennett sent a fresh specimen, confirms my determination of the 

 species and states that it belongs to his variety genuinus. 



In Europe Juncus alpinus is widely distributed, occurring from 

 Spain to Iceland, and from France and Germany to Russia. In 

 Southern Europe it is alpine and subalpine. It has also been found 

 in North-west Asia, in Greenland, and in North America. 



It is worthy of note that, as far back as 1843, Professor Babington 

 mentions it in his "Manual" as a species likely to occur in Britain. 

 From its comparatively wide distribution in Perthshire it ought to be 

 found in other parts of Scotland also. 



I should add that the Watsonian vice-counties for the species are 

 " 88 Perth Mid," and " 89 Perth East." 



New British^ Plant. I have this year gathered Carex c&spitosa 

 L. in Shetland. W. H. Beeby.
