462 JETHOU. 
enumerated in my paper on the Flora of Jethou, published in the 
Transactions of the Society for 1890. A second excursion was 
made by the Society on the 26th of June, 1894, when several 
additional species were discovered, and particular attention was 
directed to the distribution of species, and their comparative fre- 
quency. By a curious coincidence, however, these three visits to 
Jethou were made at exactly the same time of the year, viz., mid- 
summer. <A further investigation in the autumn and early spring 
might be repaid by the finding of a few novelties, though probably 
not very much remains to be added in the way of wild flowers and 
ferns. 
The only indigenous plants deserving special mention are (tr) 
the very rare Myosotis Balbistana, which I discovered in 1890 
growing under the trees: and (2) a variety of Anagallis arvensis, 
with pure white flowers, of which many specimens were found in 
1894 at the upper part of the island. The former was at the time 
new to the Channel Islands, but has since been detected in Guernsey : 
the latter is an excessively rare plant, apparently unknown in Nor- 
mandy: in our own country it has occurred in the Isle of Wight. 
‘The blue-flowered Pimpernel (4. caerulea) was also found plentifully 
in 1894, besides, of course, the common red form. 
Although this little island possesses a fairly good phanerogamic 
flora, the most interesting feature about it consists rather in what it 
has not than in what it has. Comparing it with that portion of 
Herm which lies almost within earshot, and which closely resembles 
Jethou in general character, the absence, or at any rate the apparent 
absence, of many common plants in the latter island is sufficiently 
remarkable. It is unnecessary to specify instances, as a comparison 
of the two lists will make the point clear. And then there are 
plants like Geranium molle, Bellis perennis, Achillea Millefolium, 
Flantago lanceolata, and several others ranking among the very 
commonest in the neighbouring islands, which in Jethou are ex- 
tremely rare, indeed so scantily represented as to convey the impres- 
sion that they are dying out. ‘ Hence it would seem,’ as I remarked 
in my paper above mentioned, ‘that in the grim struggle for life 
many plants which still occur in profusion on the cliff-sides of Guernsey 
are being slowly but surely crowded out of existence in Jethou by 
their stronger and more numerous neighbours. In this little island 
we can perceive the gradual change which is taking place in the 
vegetation of all countries, great and small, and the slow extinction 
of species by purely natural means, apart altogether from human 
agency. It is quite likely that in a couple of centuries many of the 
wild plants now rare in Jethou will have vanished altogether, and 
their place will be taken, not by new colonists, but by the old- 
established and firmly rooted denizens of the soil.’ 
Strictly speaking, the little islet of Crevichon forms an outlying 
part of Jethou, as the passage between them is uncovered at low 
ee
