216 GUERNSEY. 
MOSSES. 
In the very interesting catalogue of the wild plants of Guernsey, 
compiled by Joshua Gosselin in 1788, we find no less than thirty- 
one mosses enumerated under the following names :— 
Bryum pomiforme. Hypnum triquetrum. 
rurale. filiforme. 
murale. rutabulum. 
scoparium. proliferum. 
undulatum. parietinum. 
truncatulum. praelongum. 
purpureum. squarrosum. 
hornum. alopecurum. 
hygrometricum. purum. 
serpyllifolium. sericeum. 
curta. myosuroides. 
Fontinalis antipyretica. clavellatum. 
Hypnum denticulatum. cassubicum. 
complanatum. Polytrichum commune. 
sylvaticum. nanum. 
lucens. 
This list is well worth preserving as a relic of the days when the 
entire British moss-flora known to botanists did not number much 
over a hundred species. 
The alphabetical catalogue of Guernsey mosses given in the 
second edition of Ansted’s Channel Islands, p. 185, is unfortunately 
very inaccurate and misleading. Not only are a great many of the 
commonest species omitted altogther, but the list includes several 
alpine and sub-alpine mosses which could not possibly have been 
gathered in the island within recent times. In the Zvansactions of 
the Guernsey Society of Natural Science for 1892 I recorded 142 
mosses for the island, giving some account of their distribution ; and. 
a similar list, in a condensed form, appeared in the Journal of 
Botany for March 1893. Further study of certain species has 
necessitated an alteration of name in two or three cases, and a few 
additions have been made since. I am indebted to Dr. Braithwaite, 
the Rev. C. H. Binstead, and my lamented friend the late Mr. 
Henry Boswell, for much assistance in the determination of critical 
species. | 
In the following pages the names and arrangement accord with 
Dixon’s Student’s Handbook of British Mosses (1896), and the names 
used in Braithwaite’s great work, the Avritish Moss-Flora are, when 
different, added in brackets. Bryologists visiting the Channel Islands
