A REPORT ON THE FLOWERING PLANTS
Erythroea pulchella, Fries. Grows on the sand at Clacton.
Cuscuta trifolii, Bab. This parasite is, I am sorry to say,
as troublesome to our farmers as it is to those in other parts of the
country,
Calamintha acinos, Clairv. Found by myself at Blackheath,
near West Donyland.
Myosotis collina, Reich. So frequent in our neighbourhood
that I am surprised at its having been overlooked by Gibson's
correspondents.
Primula. I have occasionally noticed a Primula very like
P. elatior, Jacq., in or near the High Woods, Colchester; but as I
only found one or two plants in one place, and single specimens in
the others, I almost doubt whether they may not be varieties of
P. vulgaris.
Polygonum bistorta, L. Freely in damp meadows at Dedham.
Euphorbia dulcis, L. I found this plant in 1875 at West
Bergholt apparently quite wild, and well established. The fact was
recorded at the time in the "Journal of Botany."
Euphorbia esula, L. Has been found in a disused gravel-pit
at Witham, by Mr. E. E. Turner.
Alisma lanceolatum, With. Recorded as growing in the
Stour, by Rev. J. D. Gray.
Tamus communis, L. Frequently found throughout our
neighbourhood, but was overlooked by Gibson's correspondents.
Spiranthes autumnalis, Rich. Abundant at Berechurch, and
there is reason to suppose that it is indigenous.
Ophrys apifera, Huds. Found at Marks Tey, Walton-on-the
Naze, and at Donyland.
Narcissus pseudo-narcissus, L. Occurs at Great Bentley.
Ornithogalum umbellatum, L. Found at Great Horkesley
by Rev. J. D. Gray.
Allium ursinum, L. Grows at West Bergholt very freely.
Sparganium neglectum, Beeby. This newly recognised form
has been found in Essex, near Nayland, by the Rev. J. D. Gray. I
think it will very likely, when a search is made, be found elsewhere
in this part of Essex, as it is abundant on the Stour.
Potamogeton polygonifolius, Pourr. Occurs at Abberton.
