AUTUMN BOTANY AT CLACTON.
253
Lamium amplexicaule, L.—Field, Beacon Hill, St. Osyth.
L. hybridum, Vill.—Seen with flowers much larger than usual,
in a potato field near Coppens Green. Very much like plants
that I have seen in Surrey, and I identify both1 as the var.
dissectum of Mutel. After seeing this larger-flowered form with
its corollas in shape and size recalling those of L. amplexicaule,
I can appreciate the point of view of those botanists who
regard the cut-leaved Dead Nettle as a species derived from a
hybrid between L. purpureum and L. amplexicaule. British
botanists do not appear to be acquainted with the variations
of L. hybridum. On the other hand, French botanists recognise
three varieties, commune, decipiens, and dissectum, all probably
occurring with us.
Chenopodium polyspermum, L.—Near Sacketts Grove.
C. rubrum, L.—Roadside near Blockhouse Wick.
C. glaucum. L.—This rare Goose-foot was exceedingly abund-
ant on a site where manure had formerly been deposited near
Sacketts Grove.
Atriplex littoralis, L.—var. marina (L.).—The only place 1
saw this, was on the sea-wall opposite Brightlingsea. Elsewhere
the typical plant was the usual form.
A. angustifolia, Sm.—Clacton.
A. hastata, L.—Sandy shore west of Clacton.
A. deltoidea, Bab.—Near Little Clacton. Sandy shore west
of Clacton.
A. babingtonii, Woods.—Sandy shore west of Clacton.
Salicornia.—I paid a great deal of attention to this genus,
collecting a great many plants, examples of which have since
been seen by Dr. Moss, the curator of the university herbarium
at Cambridge, who, in recent years, has been engaged in
elucidating the many puzzling forms of this difficult group,
and is still working at these plants.
The perennial Glass-worts to be found on the shore towards
Lion Point, and beyond, are Salicornia perennis Mill. var. radi-
cans (Sm.) Moss, and S. perennis, Mill. var. lignosa (Woods)
Moss. Nearer Clacton, two annual Glass-worts grow in company.
They are much-branched plants and I could see nothing but
habit to separate them. The erect growing form is S. ram-
osissima Woods, and the recumbent plant Dr. Moss names
