BRITTEN ON SPONTANEOUS EXOTICS. '205 



Bridge of Spey, near Fochabers," Elginshire. Rev. G. Gordon, in New 

 Botanist's Guide, p. 499. A native of the Levant. 



Eapistrum rugosum, All. " One of the very commonest of the exotic 

 Crucifers in the Wandsworth steamboat station," H.B.P. 718. Here it 

 occurred for some years, but has now disappeared. 



R. perenne, All. At Wandsworth steamboat pier. See H.B.P. 798. 

 ** West Hartlepool ballast heaps, retaining its ground for many years," 

 Rev. A. M. Norman, M.S. This is, like the last, a native of Europe. 



Enarthrocarpus lyratus, D.C. " Has abounded in this [Wandsworth 

 steamboat pier] locality for some years." H.B.P. 710. I obtained a sin- 

 gle specimen from this station in 1862. See Phyt. vL, 412. N.S. " Has 

 been met with on rubbish heaps at Pendleton, near Manchester, by Mr. 

 Richard Buxton." Phyt. iv., 57. N.S. A native of Egypt. 



Raphanus sativiis, L. " Scarcely naturalized, though not unfrequent 

 in cornfields near towns and villages." H.B.P. 718. I have met with it 

 this year on Wandsworth Common, at Battersea, in one or two places, 

 and in other localities. A native of China. 



R. Landra, Mor. " Grows about Wandsworth and Battersea." H. 

 jB.P. 719. I collected two or three specimens from the Wandsworth 

 steamboat pier locality in 1863. 



Cardamine bellidifoUa, L. This is another of the species formerly 

 enumerated as genuine natives, but which subsequent investigation has 

 failed to establish as such. " On the Rock near the Quarry, by Bath, in 

 various places near the monastery at Rippon, and in Denbighshire." 

 Merrett's Pinax, p. 20. In the two last-named localities, Arabis hirsuta 

 appears to have been mistaken for it ; (See B.G. i. 173, and ii. 702.) and 

 this was probably also the case at Bath. In R. Syn. UL, 300, it is said to 

 have been " found by Mr. Newton on S. Vincent's Rock, by Bristol;" and 

 Hooker (British Flora, ed. 2, p. 301.) records it from the " County of Clare, 

 Ireland ;" a very dubious native. But no examples from these localities 

 appear to have been preserved, and it seems probable that a mistake, simi- 

 lar to that above-mentioned, must have again occurred. The locality upon 

 which most reliance can be placed is the remarkably indefinite one of 

 " Scotland," where it was '' gathered wild, and sent to Dr. Withering," by 

 Mr. Milne," {With. Arr. ed. 4, Hi., 565.) ; and from the 3rd edition of 

 English Botany it appears that " in Withering's herbarium two examples 

 of it are preserved, said to be from Scotland," (i. 224). No botanist has 

 since found it in the kingdom.
