FLOWERING PLANTS. 53 
Diplotaxis tenuifolia, DC. Wall Rocket. 
Denizen. First record: Babington, 1839. 
Frequent on the coast of the lowlands from Lerée to Belgrave 
Bay, but rather local, though usually abundant where it occurs, as on 
Vazon Green, about Pulias Barracks, and in parts of the Vale. In 
Alderney it is an abundant and troublesome weed. The flowers are 
sweet-smelling, but the foliage emits a disagreeable odour when 
rubbed. 
Diplotaxis muralis, DC. Sand Rocket. 
Colonist. First found: Gosselin, 1788. 
A rather common weed in cornfields and sandy cultivated ground 
in the low districts ; less frequent in the interior; rare in the south. 
Var. Babingtonii, Syme. Roadside near Fort George. Albecq. 
Near St. Sampson’s Bridge. This species is not mentioned in 
Gosselin’s list, but there is a specimen in his herbarium labelled 
Brassica oleracea. In the third edition of Lzglish Botany and in 
Hooker’s Student's Flora the sub-species, D. viminea, DC., is noted 
as occurring at St. Peter-Port, Guernsey, and plants gathered in the 
island within the last few years have, I believe, been referred to that 
form. It was first found here by the Rev. W. W. Newbould. 
Alyssum incanum, L. 
Casual. First record: Marquand, 1891. 
Very rare. In July. 1889, I found a single plant near Bordeaux 
Harbour: and a second specimen was gathered by Mr. C. Andrews 
In 1899 in an old quarry at L’Islet. 
Alyssum maritimum, L. Sweet Alyssum. 
Alien. First record: Marquand, 189r. 
A garden plant now established on walls in several places, and in 
dry rocky spots. On walls at Well Road, Doyle Road, Vauvert, and 
Fort George, above Clarence Battery; also at Le Préel (vi1.) and 
near the Hermitage, Lancresse. Cliffs above Fort Bay. Near 
Bordeaux. Waste places at side of lane at Les Villets (I1v.) in 1894. 
Mr. Andrews reports it as abundant in sandy places near Grandes 
Rocques in 1897 and 1898. 
Draba verna, L. Whitlow Grass. 
Native. First record: Gosselin, 1815. 
Not uncommon on dry banks and sand-hills all round the north 
‘coast from Vazon to Lancresse and St. Sampson’s ; apparently rare 
elsewhere. Mr. Derrick has seen it on the roadside wall at Swiss- 
ville, Rohais; and Mr. I. H. Burkill has shown me specimens 
collected by him at Icart Point. 
The leaves were used by the old practitioners in the form of a 
poultice for the cure of whitlows, hence its English name. Gerarde
