414 SARK. 
rare or extinct, as it has not been found of late years. Mr. Derrick 
evidently expected to meet with some of these Continental plants, as. 
he alludes to their absence in his second paper. 
Among the Sark phanerogams there are fourteen species which 
are not known to occur in Guernsey: they are as follows :— 
Ranunculus floribundus. Pyrus communis. 
Dianthus Armeria. Orobanche rubra. 
Saponaria officinalis. Mentha sativa. 
Trifolium agrarium. Lysimachia nemorum. 
Agrimonia Eupatoria. Amaranthus retroflexus. 
Rubus Balfourianus. Lemna trisulca. 
Rosa stylosa. Poa compressa. 
With the exception of a few lichens, no plants of any kind have 
been recorded from the adjacent islet of Brechou. It is not a very 
attractive botanising ground, perhaps, and is somewhat difficult of 
access: but it would be worth investigating, because, even if it 
failed to produce anything distinctive, some information would be 
gained on the subject of plant-distribution. 
The cryptogamic flora of Sark has been very imperfectly studied. 
A short list of 38 seaweeds, contributed by Miss Le Lievre, is given 
in the second edition (1865) of Ansted’s Channel Islands, p. 191. 
In a paper on the mosses collected in the Channel Islands, in 
September 1885, by the eminent French bryologist, Mons. J. Cardot, 
and published in the Revue Bryologique for 1887, seven species are 
recorded for Sark. To this meagre list I am able to add one 
species, Fontinalis antipyretica, a fine specimen of which, nearly 
eighteen inches long, was found in a well at Dosdane, by Mr. G. 
Derrick, in June 1897. Mons. Cardot records one hepatic for the 
island. The list of lichens has been compiled from the following 
sources: Leighton’s Lichen Flora, third edition (1879); Larba- 
lestier’s Lichen Herbarium (1881); Larbalestier’s Lichenes Rarissimi ; 
Crombie’s Sritish Lichens (1894). In Leighton’s book nearly all 
the species noted for Sark are recorded on the authority either of 
Mr. C. Larbalestier or of the Rev. Thomas Salwey, a well-known 
lichenologist, who spent some time in the Channel Islands about the 
year 1847. 
The following Sark cryptogams have not been recorded for 
Guernsey up to the present time :— 
Ceratodon conicus. Lecanora caesio-rufa. 
Fontinalis antipyretica. albariella. 
Leptogium humosum. pyreniospora. 
Myriangium Duriaei. diplinthia. 
Sphinctrina Kylemoriensis. Pertusaria lactea. 
Ramalina evernioides. Urceolaria actinostoma. 
intermedia. Lecidea herbarum. 
Lecanora nitens. Ptilota plumosa.
