CySTOPTERIS MONTANA, BeRNHARDI, IN STIRLINGSHIRE. 



By A. SoMERViLLE, B.Sc, F.L.S. 



Gystopteris montana of Bernhardi, the Mountain Bladder 

 Fern, is one of our rare Pteridophytes. With what may 

 be termed decidedly arctic sympathies, C. montana usually 

 selects for its habitat a moist situation in cloud-land, at 

 between 2300 and 3600 feet, with a northern (or, in one 

 case, a north-western) exposure, where it will receive but 

 little of the direct rays of the sun. 



When on Ben Lomond in August last (1894) in the 

 company of Mr. E. Kidston, F.G.S., Colonel J. S. Stirling, 

 of Gargunnock, and Dr. Pi. Braithwaite, F.L.S., author of 

 the " British Moss Flora," I had the pleasure to meet with 

 this interesting plant, previously unrecorded for Stirling- 

 shire, recognising its deltoid very compound fronds and 

 long stipes from having seen them on hills north of Glen 

 Lochay, Mid-Perthshire, in 1888, when in company with 

 Mr. Symington Grieve. Mr. Arthur Bennett, F.L.S., to 

 whom the plant has been submitted, remarks in connection 

 with it, — " I think the Cystoptcris must be C. montana, 

 though certainly the glandular setse are much less 

 numerous than usual." Fronds only were brought away 

 by me, and it is to be hoped that this local species may 

 spread at its newly found station, viz. the wet grassy 

 ledges of the precipitous cliffs of the northern face of the 

 hill, at about 3000 feet, and in company with its congener 

 G. fragilis, Bernhardi.
