F. elatior, L.—Two or three plants on low ground south 
of harbour, July 1911. 
Nardus stricta, L.—On 8th June this year my son drew 
my attention to this grass on a knoll above the harbour, 
and a week later I found it in abundance to the north of 
the lighthouse. 
Lastrea dilatata, Pres|— Among grass on low rock-ledges 
in several places in the southern half of the island, Sep- 
tember 1910. A small form, such as one meets with on the 
hills. 
Polypodiwm vulgare, L.A good-sized patch on steep 
bank, south of the loch, September 1910. It had been 
sadly spoiled by excursionists in the belief that it was the 
sea spleenwort. 
The two species above recorded, and Aspleniwm marinum, 
which grows in several places on the cliffs and in the caves, 
are the only ferns I have seen on the island.
