208 GUERNSE Y. 
FERNS. 
Polypodium vulgare, L. Polypody. 
Native. First record: Gosselin, 1815. 
Common in all parts on banks, walls, rocks, and old trees. 
Often very dwarf on walls. I have occasionally found the form with 
serrated pinnae (var. sexvatum, DC.). 
Lastrea Filix-mas, Presl. Male Fern. 
Native. First record: Gosselin, 1815. 
Rather common throughout the island, but less abundant than 
in the south-west of England. 
Lastrea dilatata, Presl. Broad Shield Fern, 
Native. First record: Derrick, 1882. 
Rather rare, and always sparingly in each locality. I have 
seen this fern in a good number of stations, chiefly in the central 
districts, but I have no note of it for the north of the island. It 
occurs at Grande Mare, and on the cliffs here and there between 
Fermain and St. Martin’s Point. 
(Lastrea aemula, Brack. On p. 182 of the second edition (1865) of 
Ansted’s Channel Islands we read: ‘The delicate Hay-scented Fern 
(Lastrea aemula) has been discovered in Guernsey by Mr..James, 
an accomplished fern-botanist resident in that island.’ It has never 
been found again, and, if the plant was really this, it was probably a 
specimen or specimens originally planted. Mr. Derrick has searched 
the island for this fern for thirty years in vain: and I could find no 
trace of it during my residence in Guernsey, although perfectly 
familiar with it from residing for several years in a part of Cornwall 
where Lastrea aemula is quite common. The absence of this 
species from these islands, however, is remarkable, as although in 
Normandy it is confined to the Department of La Manche, which 
lies immediately opposite to the Channel Islands, it is widely dis- 
tributed there and sufficiently common. Corbiere describes it as 
a ‘plante spéciale 4 la Grande-Bretagne et au nord-ouest de la 
France.’) 
Polystichum angulare, Newm. Angular Shield Fern, 
Native. First record: Derrick, 1882. 
Rare. Sparingly on the cliffs above Bec du Nez and Divette 
Cove, and on the east side of Petit Port. A few roots in the lane 
‘behind Les Vauxbelets (11.). Plentiful in the hedges of a field in 
the Talbots Valley, where it was shown me by Mr. Derrick. In 
1899 Mr. Andrews found in a lane above Les Terres ‘scores of
