210 GUERNSEY. 
Catel, Vale, and St. Sampson’s. In 47% Sarn. it is noted for St. 
Peter’s. Mr. Derrick states in his paper on the Ferns of Guernsey 
that he knows ‘quite two dozen stations for it, mostly in the town 
parish.’ . 
Asplenium marinum, L. Sea Spleenwort. 
Native. First record: Gosselin, 1815. 
Frequent all round the coast, but chiefly in the south, and in 
inaccessible spots, having been eradicated wherever it could be 
reached. Beautiful specimens with fronds a couple of feet long 
are occasionally to be seen high up the walls of some seawashed 
cavern: but the average size is much less. In Ansted’s Channel 
Islands it is stated respecting this fern: ‘Many very beautiful 
varieties of it have been described, two of them peculiar to the 
Channel Islands. Fronds measuring three feet in length have been 
found in Guernsey, but these are rare.’ 
Asplenium Ruta-muraria, L. Rue-leaved Spleenwort. 
Native. First record: Gosselin, 1815. 
Rather rare, but found in all parts of the island. I have seen 
this little fern growing on the churches or churchyard walls of every 
parish except Torteval. It is more frequent in the north, and on 
some old walls at the Vale it occurs in great profusion. 
Scolopendrium vulgare, Sym. Hart's Tongue. 
Native. First record: Gosselin, 1815. 
Very common. In the shady waterlanes of the south this fern 
attains an extraordinary size and luxuriance, fronds three feet long 
being by no means rare. Several varieties are said to have been 
found in the island. 
The patois name of this fern is Langue de boeuf. 
Ceterach officinarum, Willd. Scaly Spleenwort. 
Native. First record: Gosselin, 1815. 
Rare. Lane near Coutanchez, where in 1890 I counted eighteen 
roots on about ten feet of wall. Abundant on some of the old walls 
near Le Caudré (v1.). A few scattered plants in the vicinity of 
the Catel Church. One very large and fine root which I saw in 
1889 near the King’s Mills was dug out during the winter of 1890-1. 
Mr. Derrick has found this fern at the Vale, and reports that three 
roots which he watched for ten years hardly showed any increase in 
size. He also mentions its occurrence on greenhouse walls in 
various parts of the island. 
Gymnogramme leptophylla, Desv. 
Native (?). First found: Derrick, 1877. 
Very rare. Only known in the single locality (the hedgebank of 
a lane) at St. Saviour’s, where it was discovered in 1877 by Mr. G.
