 raises a flower-garden above the public road.

Alien. This has been reported from so many distant 

 localities since its recent discovery in Britain, that I was 

 by no means sm-prised to see the Rev. G. E. Smith con- 

 tending for its claims to " a place in the native Flora of this 

 island ;" although I cannot myself feel quite warranted in 

 admitting it as a ' colonist.' My notes of the reported lo- 

 calities, take in Devon, Herts, Essex, Cambridgeshire, Lei- 

 cestershire, Yorkshire, Hadding-tonshire and Forfarshire. 

 If I recollect aidght, the counties of Leicester and Had- 

 dington were those first reported for this plant; and it 

 does not appear- to have shown that persistence and in- 

 crease, in either of those localities, which would be ex- 

 pected in a native or fidly naturalized species. Of the 

 locality in Leicestershii-e, which had been reported imder 

 two names, Mr. Chm'chill Babington writes, " The two sta- 

 tions for Alyssum calycinum are identical. One plant (out 

 of ten which were pm-posely left growing) came up the 

 next year ; and the plant has since vanished, so far as I 

 can make out, having been probably introduced with Medi- 

 cago lupulina." In 1835, Dr. Graham reported the spe- 

 cies "profuse" on Diileton Common, in Haddingtonshire; 

 apparently deriving his information fi-om Mr. James Ma- 

 cauly. In 1844, Mr. W. Keddie found it "in small quan- 

 tities on the Common," while in company with Professor 

 Balfour, who doubtless knew where to look for it.
