212 GUERMNSE Y. 
myself knew it to grow wild in three spots in different parishes, one 
of them being Grande Mare, where there were two fine roots, but 
they disappeared shortly afterwards. At St. Peter’s the exact locality 
was kept secret, but the plants were each year dug up and offered for 
sale until all were gone: and Mr. Andrews informed me in 1900 
that not a vestige of the Royal Fern could now be seen in a 
St. Saviour’s valley where I saw four or five large roots ten years ago. 
Specimens are still preserved in Gosselin’s herbarium, and he notes 
that in his day the Osmunda grew ‘in a meadow at the Vauquiédor ; 
in the Baissieres: in the Cléture: and in the Grande Mare.’ The 
‘Cléture would be somewhere at the north end of the Vale Road, 
now probably built over or cultivated. 
*Botrychium Lunaria, Sw. Moonwort. 
Extinct. 
In his paper on the Ferns of Guernsey, Mr. Derrick remarked in 
1882, with reference to Botrychium: ‘I have heard that it used to 
be found here, but I suggest that unless guaranteed specimens are 
produced it should be omitted from the lists.’ In June, 1900, Mr. 
L. V. Lester, Principal of Victoria College, Jersey, showed me, in a 
collection of plants belonging to the College, a specimen of 
Botrychium Lunaria collected in Guernsey in 1864 by G. Wolsey, 
and marked ‘rare.’ It seems almost certain that the plant is now 
extinct, as no trace of it has been detected in the island during the 
last thirty years. 
Ophioglossum vulgatum, L. Common Adder’s Tongue. 
Native. First record: Derrick, 1882. 
Local. Occurs plentifully here and there in moist meadows in 
the low-lying districts of the Vale, Catel, and St. Saviour’s: likewise 
on Lihou Island. I have also seen it in grass fields in several 
places towards the cliffs between the Corbiere and Creux Mahié. 
Var. ambiguum, C. & G. Very rare. Grows in small scattered 
patches in several parts of Lancresse Common. The Guernsey plant 
seems to be identical with the one from the Scilly Isles, judging 
from a comparison of specimens gathered in those islands in 1890 
with some which I found near Fort Doyle in the same year. Plants 
collected on Lancresse Common in July, 1881, and sent to the Bot. 
Exch. Club, were passed by Dr. Boswell as ‘a luxuriant state of 
ambiguum.’ This variety was first described as British by Mr. F. 
Townsend in a paper entitled, ‘Contributions to a Flora of the 
Scilly Isles,’ in Journ. Bot., 1864. 
Ophioglossum ‘lusitanicum, L. Small Adder’s Tongue. 
Native. First found: Wolsey, 1854. 
The headquarters of this curious little fern are the cliffs between 
Petit Bot Bay and Jaonnet, where patches of it occur in at least
