cutting of the leaflets in these two plants are so exceeding variable as 
to afford no safe characters. 
Alyssum calycinum , L. In a field of Dutch clover, Halse, near 
Taunton, Somerset (County 5), June, 1891. Coll.: R. C. A. Prior; 
Comm. : Prof. I. Bayley Balfour. 
Erysimum repandum , L. On rubbish in St. Philip’s Marsh, Bristol, 
June, 1891 ; casual.— J ames W. White. 
E. repandum , L. Var. a, normale , O. Kuntze, ‘Rev. Gen. PL’ ii, 
932. £< Ramosissimum diffusum foliis denticulatis.” This occurred on 
rubbish heaps between Botley and Ferry Hinksey, and by the railside 
near Portmeadow, Oxford, July, 1891. — G. Claridge Druce. 
Brassica Briggsii , Watson. Waste ground at St. Philip’s, Bristol, 
West Gloucestershire, June, 1891 . — James W. White. 
Brassica elongata , Ehrh. On old colliery waste near Kingswood, 
West Gloucestershire; known some years; 7th July, 1891 .— James 
W. White. 
Viola Riviniana , Rchb. x sylvestris, Rchb. Cult, ex Hollington, 
near Shirley, S. Derbyshire, 2nd June, 1891. Permanently sterile ; 
originally growing with the two parents. — W. R. Linton. “ I think that 
Mr. Linton is probably right in his determination.” — W. H. Beeby. 
V. stagnina , Kit. Gort Racecourse, Co. Clare, Ireland, 22nd May, 
1891. — S. A. Stewart. 
V. Curtisii , Foster. Lytham Sandhills, Lancashire, 16th August, 
1891.— J. Cosmo Melvill. Mr. Melvill’s specimens have wholly 
yellow flowers, and others partly purple. See ‘Report’ 1887, p. 169. 
Cerastium tetrandrum , Curtis, f. conde?isata. Anglesey, July, 
1891. — J. E. Griffith. Is not this form mainly dependent on the 
amount of moisture ? ; on the East Coast of England the difference in 
tetrandrum in a wet or very dry season is very marked, and quite in the 
direction of this form. 
C. arcticum , Lange. Snowdon, Carnarvon, 30th July, 1891. 
Named thus for Mr. Arthur Bennett and myself by Dr. Lange himself. 
See ‘Journal of Botany,’ 1887, p. 373, 374 . — Augustin Ley. 
Arenaria ci'liata , L. Ben Bulben range, Co. Sligo, Ireland, 12th 
July, 1891. — F. J. Hanbury. Good specimens of this rare British 
species. 
A. gothica , Fries. Rocky ground, three miles from Ribble- 
head, Yorkshire, Vice County 64, 22nd August, 1890. — R. F. 
Thompson. In cultivation I quite fail to see the close approach 
(said to be) of this plant to A. ciliata , L. ; doubtless, it is only at most 
a sub-species, but the habit of the two plants is totally different. 
Acer campestre, L., var. collinum , Wallroth. Near Radley, Berks., 
October, 1891. This form with glabrous samaras stands as the type 
in the ‘ Lond. Cat.,’ but the plant of Herb. Linn, has pubescent 
samaras = var. hebecarpum , DC. See ‘Journ. Bot.,’ Dec., 1891, 
p. 377. — G. Claridge Druce. Wallroth describes this in De 
Candolle’s ‘Prod.’ i,p. 594, 1824; but in his ‘Sched. crit.’p. 188, 1822, 
he names it / 3 . leiocarpon . Why he changed the name I do not 
know; but Tausch in 1829 (Flora p. 547) took up the ‘ Sched.’ name 
var. hebecarpum , DC. =a. enocarpon , Wallrth. l.c.
