230 THE ESSEX NATURALIST.
A. Cynoglossum sylvaticum [now C. montanum] "in Hagger lane, Clay
street, and about Chingford in Henault forest, plentifully."
Alisma damasonium [now Damasonium alisma] "in ponds on the
Forest about Walthamstow & Wanstead."
Delphinium Consolida [now D. ajacis] "Buryfield. in the common
field near Walthamstow Church."
Dipsacus pilosus. "in a lane on the left beyond Ilford, near Waltham
Abby ; near Stansted Rivers" (sic.) (presumably a slip for Stanford
Rivers.)
A. Equisetum limosum. "In ditches, bogs, sides of ponds &c. very
common. It flowers in May June."
Equisetum palustre. "probably Warner meant Equisetum limosum
which is very common in gravelpits & moist ditches. Equisetum
palustre grows in Leyton Marsh near the roadside not far from the
brook near the Marsh gate—in the marsh below Westham."
Equisetum sylvaticum. "E. sylvaticum has been now found by B.M.F.
on the forest near Highbeech. probably this" [i.e., Warner's record
of this species] "means Equisetum fluviatile which grows on the
Forest near Snaresbrook & between the Epping road & Honey
Lane Green & in a wood near Chigwell—between the Red bridge &
Moss foot green—in a field between Sewardstone green and
Leppet hill."
A. Sisymbrium sylvestre [now Radicula sylvestris], "on the bank of the
Rhodon near Woodford bridge plentifully—very uncommon."
A. Aspidium thelypteris [now Lastrea Thelypteris], "in a woody bog in a
field near Epping probably forming part of Wintry Wood."
Polypodium aculeatum [now Polystichum angulare]. "Found in a
hedge the edge of the Forest on the Hawk & in a lane near Waltham-
stow Church, in a lane between Barking & a house called Jenkins
in great plenty."
A. Aspidium Oreopteris [now Lastrea montana]. "Found on the bank
of a ditch the S. side of Snaresbrook pond with Osmunda spicant"
[=Blechnum spicant] "wild near Highbeech B.M.F. bog opposite
Kings Oak. near Foxhatch & near Warley Common."
A. Aspidium spinulosum [now Lastrea spinulosa]. "In Longdown Wood
near Hale End, & on the Forest."
A. Aspidium lobatum [now Polystichum aculeatum]. "in moist shady
hedges, particularly in a lane leading from Hale End to Chapel
End Walthamstow."
Osmunda regalis. "one plant on the Lower Forest beyond Epping
1840, near to Turnpike Rood street, pointed out to me by Double-
day." This record is of considerable interest, not only botanically,
it being the latest record of the Royal Fern as occurring in Epping
Forest until my wife's discovery of a small plant near Monk Wood
in 1919,16 but also because it suggests that Edward Forster (in 1840
a man of 75 years of age) in his old age took friendly botanical
rambles with Doubleday. This record of Osmunda is doubt-
less the one included by Gibson in his Flora of Essex 1862, in
16. Essex Naturalist, xix., p. 174.
