Britton. “ This seems to me identical with Mr. Wheldon’s plant 
from Simmons-Wood, Lancs., which has been named F. carpatica^ 
Borb., in a former report (1901).” — E. F. Linton. 
V. tricolor^ L ? Turnip-field on Wraxall Hill, North Somerset, 
and July 1903. One of those puzzling forms of the Melaniiim section 
which cannot be correlated with any Continental variety, and for 
which therefore no distinctive name can be found. The most 
that can be said is that it belongs rather to tricolor than to arvensts. 
— Jas. W. White. 
Silene conica, L. Minehead Warren, v.-c. 5, S. Somerset, 
abundant, 15th May 1905. Some members may like to have speci- 
mens from the only Somerset station, which is also, I believe, 
its western limit in England. Certainly native. — E. S. Marshall. 
Silene dubia, Herbich. = S. Iranssilvanica, Schur. On exposed 
limestone rocks near the entrance to Thirst House Cave, Deep 
Dale, Buxton, Nortli-west Derbyshire, 13th July 1905. This plant 
was first noted as British by Mr. C. E. Salmon in the ‘ Journal 
of Botany’ for April 1905, p. 127. This species and its ally 
Silene nutans, L., are of frequent occurrence in Derbyshire. ^ In 
my herbarium I have examples of S. dubia from the following 
English localities, viz., Lydd, Kent, v.-c. 15, July 1904 (G. Claridge 
Druce) ; Ashwood Dale, Derbyshire, co. 57, 6th July 1867 (Rev. 
Angustin Ley) ; Millersdale, Derbyshire, 6th July 1876 (Thomas 
Whitelegg) ; near Wormhill, Derbyshire, June and July 1878 
(W; West) ; near Millersdale, Derbyshire, alt. 800 feet, July 1879 
(W. West); Millersdale, Derbyshire, 24th June 1882 (Charles 
Bailey) ; exposed rocks, near Load Mill, in the neighbourhood 
of Alstonfield, Derbyshire, 25th July J884 (Charles Bailey); and 
in Jersey, from near St. Aubyn’s, Vingtaine de Noirmont, 28th July 
1871, and St. Brelade’s Bay, 29th July 1871 (Charles Bailey). 
All these examples have been picked out of my set of Silene nutans, 
Linn., by Mr. C. E. Salmon, as being Herbich’s species. — Charles 
Bailey. “ It is the S. nutans, var. dubia (Herb.) Williams, unless 
it be specifically distinct, which, if judged by the Hieracium or 
Euphrasia standard, it certainly is. It has occurred as a casual 
in Berks.” — G. C. Druce. 
Cerastiuvi pumilum, Curt. Near Woodstock on limestone, and 
on calcareous soil near Stonesfield, Oxfordshire, April 1905. An 
interesting addition to the county flora which I predicted would be 
found. — G. Claridge Druce. 
Hibiscus Trionum, L. A few examples gathered on cultivated 
ground, Meole Brace, Shrewsbury, August 1905. The plant is well
