366 ALDERNEY. 
G. Mollugo, L. Very rare. Sparingly in the valley east of 
Val du Sud. The extreme rarity of this plant is remarkable. 
G. verum, L. Plentiful everywhere, but especially abundant 
in the sandy ground of the low-lying districts. 
G. saxatile, L. Frequent on the heaths and cliffs of the 
south-west. 
G. palustre, L. Plentiful at Longy Pond, and in two valleys. 
descending to Clanque. 
Rubia peregrina, L. Very rare. At Corbelets Bay this. © 
plant covers about twenty yards of the seacliff, but is now in danger 
of being lost owing to the deposit of quarry rubbish. Sixty years. 
ago Babington found it in the ‘eastern part of Alderney,’ which 
would probably be the same locality. The plant is now extinct in 
Guernsey, and this is the only known locality for it in these islands. 
VALERIANACEAE. 
Centranthus ruber, DC. On walls in various places on the 
outskirts of St. Anne’s. 
Valerianella olitoria, Moench. Very rare. After much 
searching I discovered a few plants growing intermixed with V. 
carinata on the roadside near Watermill Farm, but I have not. seen 
it again. This species is so common in Guernsey that its rarity in 
Alderney is rather remarkable. 
V. carinata, Loisel. Very common everywhere. 
V. dentata, Deitr. In a cultivated field at Rochers, fairly 
plentiful in 1g00. 
V. eriocarpa, Desv. Generally distributed and frequent in 
the eastern half of the island, and plentiful in the spots where it 
occurs. Closely resembles V. cavinaza, but the flowers are brighter 
coloured, and the fruit at once distinguishes it from all others of the 
genus. I consider this plant undoubtedly native in Alderney, 
judging from its distribution and the various kinds of localities in 
which it grows. It has not been found in any of the other islands. 
DIPSACACEAE. 
Knautia arvensis, Coult. Rare. Scattered plants in many 
places on Rochers Hill.
