Probably many more species would have been observed had it
not been high water at the time of my visit, and that only a few of
the pools were uncovered close to high-water mark.
FLOWERING PLANTS.
The following species were observed by the roadside and on the
beach between Harwich Station and the small breakwater near
Dovercourt. They are given in the order in which they were ob-
served :—
Chenopodium olidum, Hordeum maritimum, Helminthia echioides,
Anthemis cotula, Borago officinalis, Rumex pulchra.
Mentha sp. ? This plant had large coarse leaves, like those of
Mentha aquatica, but having a purplish tinge and a strong taste of
peppermint. It was not in flower, but may perhaps be Mentha
piperita, L. b sylvestris, Sole. It grew in a small grassy enclosure
between a lane leading to the beach and the first gate in the main
road to Dovercourt.
Lamium amplexicaule, Torilis nodosa, OEthusa cynapium, Malva
sylvestris.
