water ; and yet its vegetation differs, since two phanerogams (Hedera 
Helix and Euphorbia amygdaloides) and four ferns, which have been 
found upon it, are not known to grow at all on the main island. It 
seems better, therefore, to treat this curious little pyramidal rock as a 
distinct area, for its flora certainly deserves to be described sepa- 
rately. By comparison, Crevichon is rich in ferns, which are all 
exceedingly rare in Jethou proper, with the sole exception of the 
common Bracken. 
The few lichens recorded by Leighton and Crombie probably do 
not represent a tenth part of the number that could easily be found, 
but the island has never been properly searched for cryptogams. 
The flora of Jethou as recorded in the following pages consists of 
179 Flowering Plants, 7 Ferns, and ro Lichens. 
Ranunculus acris, L. Recorded by Babington. 
R. repens, L.- Rare. 
R. bulbosus, L. Very rare.

localities at the top of the island. 
Papaver somniferum, L. Plentiful but small at the northern 
end, mostly in the cultivated plots. 
Fumaria confusa, Jord. In the cultivated plots, scarce. 
F. officinalis, L. Recorded by Babington. 
Cardamine hirsuta, L. Local. 
Sisymbrium officinale, Scop. Frequent.
