Native. Uliginal. A very local plant, and satisfactorily 

 ascertained in the East Highland province only. It oc- 

 curs on several parts of the Breadalbane mountains, near 

 Loch Tay, in Perthshire. And it has been re^jorted (with 

 more or less susj)icion of inaccuracy in several of the lo- 

 calities) from Goat Fell, in Arran ; from the Clova Moun- 

 tains, in Forfar; from Glass Mhiel, on the confines of 

 Forfar and Aberdeen ; from Cairngorum, at the junction 

 of Aberdeen, Banff, and Moray ; from Ben Nevis, in West 

 Inverness. Also, from the very improbable station of 

 " Links of St. Fergus," by Mr. Murray, in Flora Scotica, 

 the authority for Arran and Ben Nevis. Mistakes may 

 readily be made between this and J. triglumis, from the 

 similarity of the plants, and similarity of the written 

 names. Perhaps this species may occur both higher and 

 lower than is indicated above.
