. aviculare, L., are sent by Mr. Briggs from Wembury, Devon. The 
plant has much the look of P. Raii, Bab., but is a greener plant, with 
a smaller nut, which is not polished as in that species. 
Rumex pratensis, M.and K. Near Boar's Hill, Berks ; W. T. Dyer. 
Additional to sub-province 9 of Cyb. Br. Supp. 
Euphorbia Lathyris, L. Said to be “completely naturalized” at 
Frodsham, Cheshire; J. T. Robinson. 
Salix undulata, Ehrh. This appears to be the commonest Willow 
upon the banks of the Thames in the neighbourhood of Richmond, 
both upon the Middlesex and Surrey banks. Mr. Baker has contri- 
buted a supply of specimens. It is also common on the Middlesex 
shore, even as far down as Chelsea, whence Dr. Trimen sends speci- 
mens. 
Salir Grahami, Borrer. Mr. Baker has called attention to a plant 
found in Sutherlandshire by the late Professor Graham, and preserved 
in Mr. Borrer's herbarium at Kew, with the above name in MS. (See 
‘Journal of Botany,’ Vol. V. p. 157, and tab. 66.) Botanists in the 
north will do well to examine apparent varieties of S. herbacea, with a 
view to the refinding of this species. 
Iris acoriformis, Bor. With a few specimens collected at Green- 
wich, Kent, and so named; Mr. Syme writes, “ This is the only one 
of Boreau’s three forms of Iris pseud-acorus that I have seen by the 
Thames, along which river it extends to my knowledge from Streatley, 
Berks, downwards. The Z. pseud-acorus, Bor., I have in my garden, 
the root was brought from Deal. Of the 7. Bastardi, I have seen 
but one British specimen, from Lord Mansfield’s fishponds near High- 
gate.” . 
Allium carinatum, L. (See * Journal of Botany,’ Vol. V. p. 314.) 
This well-marked species is recorded from Nottinghamshire, where 
it was discovered in August, last year (1867), by the Rev. W. S. 
Hampson, between Brandon and Doddington, near Newark, amongst 
coarse grass and rushes. The following description is taken from 
Grenier and Godron’s Fl. Fr. vol. iii. pp. 207-8 :—“ Bulb simple, 
ovoid, greyish. Stem 1} to 2 ft. high, straight or slightly flexuose, 
cylindrical, leafy up to the middle. Leaves. upright or ascending, 
linear, fleshy, flat upwards, slightly channelled below, almost 
smooth or a little furrowed beneath, not keeled, scabrous on the 
edges. Umbel many- or few-flowered with many or few bulblets.
