THE MOUNTAIN BLADDER FERN. 275 
This species grows on mica schist in moist alpine situations. 
Tt was first found in Great Britain, on Ben Lawers, in Perthshire, 
by Mr. W. Wilson, in 1836. It has been subsequently met with by 
the late Mr. W. Gourlie, Dr. Arnott, Mr. W. Borrer, Rev. W. 
Little, Mr. T. Westeombe, and other botanists, on the mountains 
dividing Glen Lochy and Glen Dochart, in the same county. The 
locality is variously described. Mr. Gourlie calls it Corrach 
Uachdar. Mr. Borrer observes that *the station is recorded under 
the name of Corrach Uachdar, but a native of the neighbourhood 
calls the mountains Meal Qufillach, and the ravine Corrach Dh’ 
Oufillach, as nearly as I could express his pronunciation :"' this 
station is some miles up the glen, and is described as being on. the 
left hand over against Mael Ghyrdy. Mr. Westeombe could find 
no one in the district who recognised the foregoing names, but after 
a diligent search he met with another locality some six or eight 
miles from where Mr. Borrer had found it. Hooker and Arnott 
give Meal Cuachlar as a habitat. More recently it has been 
gathered in the same districts, by Dr. Balfour, and Mr. G. Maw ; 
and also in Canlochen at the head of Glen Isla, Clova, Forfarshire, 
by Mr. J. Backhouse, to whom we are indebted for specimens. 
In the Canlochen station, Mr. Backhouse met with it in consider- 
able quantity, and in fine fructification. It is further recorded 
in the Naturalist as having been found, in 1855, on Ben-rinnes 
(P Belrinnes, a mountain of Banffshire). There is moreover, a 
statement that this plant has been found in Wales, but the figure 
of Plukenet referred to in support of this habitat, certainly does not 
represent the present species, and Mr. Newman appears to have 
satisfactorily shown thatit belongs to some mountain form of Buckler 
Fern, and probably to Lastrea emula. 
This Fern is found in the extreme northern parts of Europe, in 
Lapland, in the north of Sweden, Norway, and Denmark, thence 
scattered here and there southwards on the mountain ranges of 
central and southern Europe, namely in France, Switzerland, 
Germany, Spain, Italy, and Hungary. Aecording to Ledebour, 
it is met with in Kamtschatka. It is also found among the 
Rocky Mountains in North-West Ameriea. Another triangular
