384 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Folygo 9 ium avicnlare, L,, var. Marcham, Berks, August, 1892. 
Gathered in the company of Mr. J. Gilbert Baker, who thinks it var, 
littorale (Link.) — G. C. Druce. “ It is var. agresthmm, I believe.” — 
Arthur Bennett. “ I am afraid it will not do to call it var. litorale, 
which has seeds protruding much more, and rather larger. Without 
further examination, I should venture to call it rurivagum^ which has 
nut a little longer than perianth. In fact, I think it is that. A similar 
plant used to come up as a weed in my garden at Sprowston, and at 
first I thought it was inland var. litorale.” — E. E. Linton. Mr. 
Marshall says “ certainly not littorale 
F. mite y. Fersicaria. Osney, Oxon, September," 1892. — G. C. 
Druce. “ Looks probable, but I don’t know them critically.” 
E. S. Marshall. It grew with both parents, and I have little doubt of 
the correctness of the determination. It is not quite identical with 
the plants No. 1832 of the ‘Flora Exs. Aust. Hung.’ named F. 
axillare Rigo = mite x Fersicaria, which has rather broader leaves. — 
G. C. Druce. Dr. Lange considers it to be correctly named. 
F. sagittifolium, L. I sent this plant to the Club in 1889 under 
the name F. arifolium ; it was then ^ound growing abundantly on 
the stony bed of a small stream, just above tidal influence, at 
Castle Cove, Kenmare Bay. On re-visiting this locality with a friend 
last summer, a careful search could only discover one or two small 
plants still surviving on this flood-swept spot, while perhaps half a 
dozen more were found along the stream nearer the sea. Later in 
the day, when following an old deserted road across the mountains to 
Darrynane, we came across a small boggy hollow, quite filled with 
this prickly Folygonum. This new locality is about a mile north of 
Castle Cove and about 200 feet above sea-level. Jiincus tenuis^ 
another common American plant, occurs in great abundance near 
this locality. 22nd July, 1892. — R. W. Scully. 
Riimex dentatus, Camp. Waste ground, Foss Island, York, 
Aug., 1889. — J. A. Wheldon. Yes; an Eastern plant referred to 
in the ‘Flora of British India’ as R. dentatus, Linn., ‘Mantissa,’ 
p. 226, and in Boissier’s ‘Flora Orientalis,’ iv., 1013. In the 
‘ Prodromus,’ xiv., p. 56, it is cited as R. dentatus, Campdera 
‘Monograph des Rumex’ (1819), p. 64 et 81, on account of the 
uncertainty attaching to the plant of the ‘ Mantissa ’ and of Murray 
in ‘Comm. Gott,’ 1774, p. 46 t. 10 etc. — G. C. Druce. 
R. sanguineus, L., var. trigranulatus. Meadow, Wilton, 
tierefordshire, loth August, 1S92. — Augustin Ley. “Originally 
called a trigranulate form of R. nentorosus by Mr. Archer Briggs (‘Bot. 
Ex. Club Report,’ 1876, p. 30, ‘FI. Plymouth,’ p. 294). I have not 
seen Mr. Briggs’ specimens, but I possess what I believe to be the 
same plant from Harley, Surrey, gathered many years ago.” — Arthur 
Bennett. Rev. W. R. Linton thought his specimen was R. 
conglomeratus, Murray. 
R. acutus, L. Sneyd Park, Clifton, West Gloucester, 13th 
July, 1892. This plant is frequently met with about Bristol, both in 
N. Somerset and West Gloucester. — Jas. W. White. “Yes.” — 
Arthur Bennett.
