206 I'HE NATURALIST. 



Barbdrea intermedia, Bor. This is an agrestal weed of comparatively 

 recent introduction. It appears to have been first noticed by Mr. A. G. 

 More, in the county of Armagh, Ireland, in 1844, growing " in cultivated 

 fields, where it was an abundant weed, and I think some younger plants 

 from roadsides adjoining were the same." Phyt. iv., 88. N.S, In York- 

 shire it appears to have been twice observed by Mr. Baker : in 1863 " in 

 cultivated fields at the lower end of Bilsdale, on the slope of Easterside 

 towards Hawnby," [North Yorkshire, p. 203) ; and in 1863, " in a second 

 North Yorkshire station." {Thirsk Report for 1863, p. 6.) It has been 

 seen in cloverfields " in the neighbourhood of Manchester," by Mr. Bux- 

 ton and others, {Phyt. iv., 103. N.S.) ; and appears to have been found by 

 Mr. Hardy, at Hulme, in the same county. See Phyt. iv., 88. N.S. In 

 the 3rd edition of English Botany, it is recorded from " near Bowden, 

 Cheshire ; and Mr. J. G. Baker has seen it near Dorking, Surrey." i. 170. 

 In the latter county it was " plentiful in a field of Trifolium incarnatunif 

 near the Box Hill railway station ; May, 1863," {Flora of Surrey, p. 360.) ; 

 and here also was observed by Mr. Baker. In the Thirsk Report as above, 

 we are told that Mr. Briggs sent, in 1863, " a specimen from Devonshire, 

 from a quarry between Saltash and Plymouth ;" a locality to which it may 

 possibly be indigenous. It will probably occur in cultivated ground in 

 other parts of the kingdom ; but it has not yet appeared in Scotland. 



Erysimum virgatum, Roth. The appearance and disappearance of this 

 species in the neighbourhood of Bath is a very curious circumstance. In 

 1844 the place of E. cheiranthoides was here " supplied by this plant." 

 C. C. Babington, in Phyt. i., 310. O.S., it is stated to be no longer found 

 about Bath. It hath also occurred in Yorkshire, having been '' met with 

 by Mr. Ward, in Swaledale, between Reeth and Marrick." {North York- 

 shire, p. 204.) It is a native of Portugal. 



E. Perofskianum, Fisch. This common and ornamental garden annual 

 occasionally occurs on rubbish-heaps, and was noticed last year on the 

 waste ground at Kew Bridge. A native of Cabul. 



E. orientale, Br. Appears to have grown in Ray's time on sea-cliffs, 

 near Harwich, in Essex ; and on cliffs about Bardsey, near Orford, in 

 Suffolk, (See R. Syn. Hi., 993.) But as we have no reeord of its recent 

 occurrence here, we must suppose it to have failed in maintaining its 

 position. It has since been noticed in several other localities, though 

 usually under suspicious circumstances : in Sussex it occurred in " fields 

 near Mayfield and near Maresfield." {Coopers Botany of Sussex, 1834) ;
