seeds." Phijt. HI, 387, 338. N.S. In Yorkshire it is stated by Mr. Baker 

 to be " an occasional straggler from cultivation. During each of the last 

 three or four years I have usually noticed a few plants in waste places, in 

 the vicinity of Thirsk, Rievaulx, etc." Supp. to Flora of Yorkshire (1854), 

 p. 41. In his " North Yorkshire " Mr. Baker gives the additonal locaUties 

 of Cotherstone and Ainderby Steeple (p. 199). The above evidence is 

 sufficient to show that G. phcenicium has no claim to a place among our 

 native plants. 



Ghelidonium laciniatum, D.C. " Observed plentifully among the 

 ruins of the Duke of Leeds' seat at Wimbleton by Mr. Martin." R. Syn. 

 Hi., 309. Since the period of the above notice, the plant appears to have 

 spread in the neighbourhood, for in H.B.P. 736, it is stated to grow " about 

 Wimbledon, under hedges and on old walls." " A very doubtful native." 

 Bab. Man. ed. 5, p. 17. 



Hypecoum procumbens, L. This native of the South of Europe for- 

 merly occurred on the waste ground at Wandsworth steamboat pier.

Platystemon californicum, Benth ? This, ** or some other more re- 

 cently introduced species," appears to have been found near Birkenhead. 

 See Phyt. iv., 384. N.S. It is a native of California. 



Order III.* — FuMAniACEiE. 



Dielytra formosa, D.C. '' Subspontaneous, or planted in a wood near 

 the High force of Seamerdale, plentiful in 1859, Wheldon ! A native of 

 America." Baker's North Yorkshire,]). 199. 



Order IV. — Crucifer^. 



As might be supposed, so large an Order as this furnishes a propor- 

 tionate number of introduced species, of which besides those which follow, 

 there are several as yet undetermined. 



Iberis umbellata, L. This common garden annual is a native of the 

 South of Europe, and occurs not unfrequently on waste ground near the 

 Metropolis. I collected it last year from the waste ground at Kew Bridge : 

 and have this year met with it in some abundance about Battersea Park ; 

 it has also recently occurred on waste ground near the Wimbledon rail- 

 way station. In the London Flora, p. 169, the " Old Palace, Croydon," is 

 given as a locality for it. I have seen a specimen gathered in June last 

 in a cornfield near Medmenham, Bucks, where it occurred in small quan- 

 tity ; Rud in the following month, I observed a single plant growing in the
