My Dear Sir

I fortunately found my Brother¹ in Town last evening.—

He tells me that there has been no case of a composite or hybrid raceme in the Laburnum grafted with Cytisus purpureus, it seems also an interesting fact that the purple blooms have not produced seed, he thinks none at all, whilst on the other hand the yellow racemes have produced seed, these the gardener has sown and some strong plants have been reared.—²

There are also some curious cases in his garden of Cratægus oxyacanthus grafted with pink double varieties, producing each year some branches which bear white blooms, this may be a sport or the effect of the stock.—³

Since I wrote about the variegation of green ivies by being pla⁠⟨⁠  ⁠⟩⁠ on a wall near the variegated variety, Hedera helix aurea robusta, I have had several more cases of other varieties of ivies being stained with yellow by propinquity with the variety above stated.—⁴

Believe me | My Dear Sir | Yours very truly | J Jenner Weir
