Sycamore 1 Robinia 1 From this it would appear that notwithstanding the BRITISH OAK grows everywhere, it is at present only favoured by the companionship of the mistletoe in equal ratio with two comparatively recently introduced trees. Indeed such objection does this parasite manifest to the brave old tree, even in his teens, that, notwithstanding a newly-planted line of mixed trees will become speedily attacked by it, the oak is certain to be left in his pride alone. I have, however, seen the mistletoe on the oak in two instances during my much wandering about amid country scenes, especially of Gloucester and Worcester, two great mistletoe counties. One was pointed out to me by my friend, Mr. Lees, from whom we may expect much valuable information on this subject, in his forthcoming edition of the _Botanical Looker-out_--it was on a young tree, perhaps of fifty years, in Eastnor Park, on the Malvern chain. The other example is at Frampton-on-Severn, to which the President of the Cotteswold Naturalists' Club, T. B. L. Baker, Esq., and myself, were taken by Mr. Clifford, of Frampton. The tree is full a century old, and the branch, on which was a goodly bunch of the parasite, numbered somewhere about forty years. That the plant is propagated by seeds there can, I think, be but little doubt, as the seeds are so admirably adapted for the peculiar circumstances under which alone they can propagate; and the want of attention to the facts connected therewith, is probably the cause why the propagation of the mistletoe by artificial means is usually a failure. I should be inclined to think that the mistletoe never was abundant on the oak; so that it may be that additional sanctity was conferred on the _Viscum guerneum_ on account of its great rarity. JAMES BUCKMAN. Cirencester. _Mistletoe upon Oak_ (Vol. ii., p. 214.).--Besides the mistletoe-bearing oak mentioned by your correspondent, there is one in Lord Somers' park, near Malvern. It is a very fine plant, though it has been injured by sight-seeing marauders. H. A. B. Trinity College, Cambridge. _Mistletoe_ (Vol. ii., pp. 163., 214.).--Do I understand your correspondent to ask whether mistletoe is found now except on oaks? The answer is, as at St. Paul's, "Circumspice." Just go into the country a little. The difficulty is generally supposed to be to find it _on_ the oak. C.
