Among the more interesting of the manuscript records,
whether from the botanical or from the local topographical point
of view, are the following, those which were additions to Warner's
list being marked with an A :—
Geranium pyrenaicum "One plant in Shernal street near Tinkers
brook bridge."
A. Valeriana rubra [now Kentranthus ruber]12 "on Mr. Shepherds wall
Upton."
Acorus calamus "in a pond in a lane between Chigwell Row and the
road & in Mr. Lockwood's Deuxhall park, Lamborn."
Asplenium Adiantum-nigrum "on a wall in Capworth street, at Wans-
stead B.M.F.,13 on the wall of a Haha in front of House near Bush-
gate Wanstead."
Allium vineale "in the marshes near the Path leading from Waltham
stow Marshstreet to Lea bridge & in the lane leading from Hoe
street to Marks house common field & elsewhere, in Higham hill
field, on a bank in Angel lane Leyton."
A. Alsine marina [now Alsine marginata]. "In Plaistow Levels, and
near Rainham Creek."
Sagina erecta [now Moenchia erecta]. "on the Forest near Woodford."
11. i.e. of T. F. Forster's Additions of 1784, where this plant is duly recorded. Edward
Forster there notes, "This was found by Warner in the lane & Churchyard at Chingford & is in
his MS. Additions" ; and he adds the additional stations "near Chingford Church, and in the
marshes near Barking Creek in the way to Wall End."
12. The modern nomenclature given in square brackets is that followed by the British
Museum authorities.
13. The initials B.M.F. occur several times against records, and denote that the particular
record rests on the authority of his brother Benjamin Meggot Forster. It is pleasing to see
how the brothers gave due credit to each other for their discoveries. Cf. Benjamin's own record,
Essex Naturalist, xix., p. 85.
