REPORT FOR 1892

strap-shaped segments, and its larger flowers rather suggest ,S. 
orientale, L. This can be distinguished from .S'. Si?iapistrum, Crantz, 
as Boissier in the ‘FI. Orient.’, vol. i., p. 216 points out, by the 
calyx being closed calyce clauso^') in S. Columnce^ Jacq. = 
S. Ortentale, I., whWe S. pannonicum,]^c(\. = S. Sinapistrum, Crantz,

Sisymbrium repandiim^ L. Ballast, Birkenhead, Cheshire, 7th July, 
1892. — J. A. Wheldon. This was thought by a critical botanist to 
be A. Columnce, but the hairs on the leaves and stems of this plant 
are adpressed, and the leaves are only faintly toothed, not runcinately 
cut as in that plant. Its proper name is ErysUnum repanditm, Linn., 
being described by Linnaeus in the ‘ Amoen. Acad.’ iii., 415, and 
figured in ‘ Reichb. Ic. Helv. et Germ.’ 4384, but from rather an 
unhealthy specimen. It is a casual of increasingly frequent occurrence. 
It occurred rather plentifully near Didcot, Berks, this last season. — 
G. C. Druce. 
Erysimum perfoliaium^ Crantz. Weed in an oat field, Walton, 
Lancashire, July, 1892. — J. A. Wheldon. Bentham and Hooker, 
in the ‘ Genera Plantarum ’ keep the genus Conringia distinct from 
Erysimum, as does Durand in his ‘ Index.’ This plant belongs to 
Conringia, and its oldest name that I know under that genus is C. 
perfoliata. Link, ‘En. Hort. Berok’ ii. 172, 1822. Those botanists 
who are in favour of retaining the original specific name will probably 
prefer C. orienialis, Andr. in DC. byst. ii. 508, and Dumort. ‘ FI. 
Belg.’ 123 (1827) since it was the Brassica orienialis of the ‘ Species 
Plantarum.’ — G. C. Druce. 
Camelina sativa, Crantz. Rail side, Didcot, Berks, August, 1892. 
G. C. Druce. “ Seems to be this rather than C. foetidaP — Arthur 
Bennett. 
Thlaspi perfoliatum, L. Stony ground near Charlbury, Oxon, 
April, 1885. — G. C. Druce. 
Bunias orienialis, L. Woolwich Arsenal, Kent, June, 1892. — 
A. H. Wolley-Dod. 
Helianihemmn Breweri, Planch. Holyhead, Anglesey, June, 
1890. I think the plant which I gathered with the above, and 
referred by Mr. J. G. Baker to true H. guiialum, is ebracteate H. 
Breiveri, in which the shape and texture of the leaf differ somewhat 
from the Jersey plant. In that case, if H. Breweri be kept distinct, 
it may be distinguished as var. ebracieaia. Willkomm and Lange 
place our H. guiiaium in the genus Eiberaria as Tuberaria variabilis, 
Willk. var vulgaris, sub-var. Milleri. — G. C. Druce. 
Viola odorata, L. var. imberbis, Leighton. Wood above Mickleham, 
Surrey, ist May, 1892. — A. H. Wolley-Dod. This was first described 
as Viola imberbis by Leighton, in ‘Loudon’s Mag. Nat. Hist.,’ vol. viii., 
277, but in the ‘Flora of Salop,’ p. 116, Mr. Leighton, following 
Henslow (in 2nd Ed. of ‘ Lond. Cat.’) reduced it to a variety of V. 
odorala. It is a white flowered form in which the lateral petals are 
destitute of the hairy line, a character not influenced, Mr. Leighton 
found, by cultivation. I have the same plant from Oxon and Berks. 
The purple flowered form has also been found. — G. C. Druce.
