First record : Watson, 1837. This plant was not distinguished from the 

 preceding by British botanists previous to Smith ; there are no specimens 

 in the herbaria of Buddie or Petiver ; nor is it given in Kay's Synopsis. 

 It is not improbably a comparatively recent introduction First 

 noticed in England near Eamsgate, Kent, by Mr. Dillwyn in 1801 

 [Linn. Trans, vi. .389),* where it was said to have been introduced 

 with foreign oats. It quickly became a troublesome cornfield weed 

 there, and is so still throughout the I. of Thanet. The larger form, 

 3 Babingtonii (Syme) appears to be the more common about 

 London. 



Lunaria biennis, Monch. Honesty. White- Satin. (Viola Lunaria s. 

 Bolbonac. Hath been found wild in the woods about Pinner and 

 Harrow-on-the-HiU ; Ger. 378.) No doubt an error; the plant is 

 common in gardens, and single plants sometimes occur on waste 

 ground, as in (V.) a newly made road at Chiswick.

* It had previously been detected by Dr. S. F. Gray of the British Museum (where, 

 we are not told), but was considered a variety of D, tenuifolia by him and Smith. (See 

 under Sisymbrium Irio, E. B. 1631.)
