AUTUMN BOTANY AT CLACTON. 
2 5 I 
St. Osyth Creek, as to almost exclude all other vegetation. 
With it occurs, here and there, Lactuca saligna and Atriplex 
littoralis. 
I have already mentioned how interested I was in observing 
that the usual hedgerow tree about Clacton is the small-leaved 
elm— Ulmus saliva, Mill. In Surrey, the usual elm is that species 
called by Dr. Moss Ulmus campestris of Linnaeus. In my own 
neighbourhood I am acquainted with but one tree of U. saliva. 
In addition to those previously mentioned, the following 
are the more interesting plants seen by me in the vicinity of 
Clacton :— 
Erysimum cheiranthoides, L.—Clacton, near Coppens Green. 
Brassica nigra, Koch.—Near Martello tower beyond Lion 
Point, Great Clacton ; about Blockhouse Wick, St. Osyth. 
Diplotaxis muralis, D.C.—Clacton, both annual and forms 
of longer duration. 
Lepidium ruderale, L.—Seen as a plant of waste places, 
between Great Clacton and Little Holland, and as a member 
of the sea-wall vegetation by Brightlingsea Creek. 
Tlilaspi arvense, L.—Remarkably abundant in cultivated 
fields about Clacton. 
Reseda lutea, L., and R. luleola, L.—Clacton. 
Arenaria leploclados, Guss.—Field near Rush Green. 
Spergula saliva, Boenn.—Cultivated field above Clacton 
Cliff.

Osyth. 
Medicago arabica, Huds. (M. maculala, Sibth.).—Sandy shore 
near Lion Point ; between Great and Little Clacton.

Rosa comosa, Rip. (Sweet Briar).—Coppens Lane. 
R. arvensis, Huds.—Between Coppens Green and Booking’s 
Elm.

in the immediate vicinity of Clacton.)

and Little Holland Common. 
Conium maculatum, L.—Between Great Clacton and Great
