348 ALDERNEY. 
During the sixty years that have since elapsed, many English 
and French botanists have visited Alderney, but I am not aware that 
any additional information has been published on the subject. 
Feeling certain that there was yet much to be learnt about the 
botany of that little island, I spent the summer there in 1899, and 
compiled a list of 426 phanerogams and ferns, one-third of them 
being unrecorded by Babington. This list was published in the 
Transactions of the Guernsey Society of Natural Science for 1899. 
Another year’s work has enabled me to fill up several gaps and add 
a good many species to the list, so that the phanerogamic flora of 
Alderney may now be considered fairly well worked up. 
Any one sufficiently acquainted with the flora of Guernsey and 
Sark will find Alderney exceedingly interesting, not only on account 
of the striking difference in the distribution of many of the species, 
but also because the number of plants which do not occur elsewhere 
in the area now dealt with is relatively large. Alderney is one-sixth 
of the size of Guernsey, and yields, in roun! numbers, two-thirds of 
the phanerogams: but no less than thirty-seven of these, or seven per 
cent. of the total, have not been found in the larger island. The 
following is a complete list so far as known at present :— 
Cochlearia officinalis. Tragopogon minor. 
Helianthemum guttatum. Picris hieracioides. 
Dianthus Armeria. Crepis taraxacifolius. 
Silene nutans. Cuscuta trifolii. 
Geranium sanguineum. Orobanche Rapum. 
Vicia varia. Calamintha Clinopodium. 
Onobrychis sativa. Statice lychnidifolia. 
Agrimonia Eupatoria. Thesium humifusum. 
Rubus Idaeus. Salix purpurea. 
Rosa involuta. stipularis. 
tomentosa. aurita 
stylosa. Orchis pyramidalis. 
Sedum Telephium. Juncus glaucus. 
Asperula cynanchica. Trisetum flavescens. 
Valerianella eriocarpa. Avena pubescens. 
Diotis maritima. Poa sudetica. 
Arctium nemorosum. Briza media. 
Centaurea Scabiosa. Equisetum maximum. 
Carduus acaulis. 
With the exception of some lichens, no cryptogamic plants have 
hitherto been recorded for Alderney, and the present lists simply 
give the result of my own researches during the year tgoo. They 
must be regarded as suggestive rather than exhaustive. 
The air is so dry here that the moss-vegetation is far less 
luxuriant than in Guernsey. The occurrence, however, of such an 
excessively rare British moss as Bartramia stricta (a species confined
