Leafing of Oak and Ash. — I noticed Oak trees in leaf on the 11th 

 inst., and I did not see Ash trees as forward until the 24th inst., so I 

 consider, this season, the AsL hereabouts a fortnight later than the Oak. — 

 E. C, Chaddesley, Kidderminster, 27th May, 1880. 



White Varieties of Plants. — It may interest some of your readers to 

 know that a plant of Ajuga reptans, which I transplanted to the garden 

 two years ago, continues constant. This year it has thrown up numbers 

 of heads of pure white flowers. Though I left part of the root in the 

 wood where I found it, I cannot discover any trace of it there now. In 

 the adjoining field I gathered, on the 4th of this month, a pure white 

 specimen of Pedicularis sylvatica. With regard to the proliferous 

 Cardamine mentioned at page 67, (March last,) it proves to be Cardamine 

 l>ratcnsis. — A. E. J., Hattou, June 12th, 1880.
