B52 ALDERNE Y. 
CRUCIFERAE. 
Nasturtium officinale, R.Br. Common on streamsides and 
in wet places generally. 
Barbarea praecox, R. Br. Half a dozen fine plants in an old 
quarry at Rochers. 
Arabis hirsuta, R. Br. Common on the moorlands and in 
‘dry, sandy places: often on tops of walls. 
Cardamine flexuosa, With. Slopes of Essex Castle Hill. 
Marshy place towards Corbelets. Rose Farm Valley. 
C. hirsuta, L. Common. 
Sisymbrium officinale, Scop. Very common. 
Alliaria officinalis, Andrz. Rare. Reuters Valley, plenti- 
fully. In 2 Sarn. it is noted for Platte Saline, but it does not 
‘grow there now. 
Brassica campestris, L. The var. napus, L., is frequent 
on the Blaye; occasional elsewhere in cultivated ground and on 
roadsides. 
B. Cheiranthus, Vill. Recorded for Braye Bay in 47. Sarn. 
I have searched for this plant all over the island, but in vain: per- 
haps it is now extinct. 
Sinapis arvensis, L. Abundant in cultivated ground, 
especially on the Blaye, where it sometimes grows so thickly as to 
form the principal crop of the field. On the shore at Longy Bay I 
have noticed the var. wéd/osa, Mérat, growing with the type. 
S. alba, L. Rare. One large clump at Platte Saline, on the 
sea bank below Fort Tourgis. 
S. incana, L. Abundant in the neighbourhood of Braye Bay: 
and more or less frequent all over the eastern half of the island. 
Both the forms mentioned in #7. Saru. grow here. 
Diplotaxis tenuifolia, DC. An abundant and pestilent 
weed in dry pastures and on hillsides, especially on the east side of 
the island. I have been assured that this plant was introduced into 
Alderney at the time of the Government works: but it certainly 
existed here before the year 1838, as it is mentioned in FZ. Sarn. as 
occurring at Platte Saline and Braye Sands.
