BUCKLANDIA (named after Dr. Buckland, a former Dean of Westminster, and Professor of Geology at Oxford). ORD. Hamamelideæ. A handsome greenhouse tree, allied to Liquidambar. It thrives in rich sandy loam, peat, and leaf mould; or peat may be left out if the leaf soil is good; perfect drainage is also essential. Cuttings of ripened shoots will strike in sandy loam, under a hand glass, with moderate heat. They must be watered carefully, or they are liable to rot off.
B. populnea (Poplar-like). l. pale green, large, leathery, cordate, ovate-acute, on long stalks, pinkish when young; stipules very curious, large red, consisting of two leafy oblong plates, placed face to face in an erect position between the leafstalk and the stem. h. 100ft. Himalayas, 1875. (B. M. 6507.)

BUDDING. This process consists of taking an eye or bud attached to a portion of the bark, and transferring it to another and different plant; it is an operation almost confined to woody plants, but has been practised with more or less success upon herbaceous perennials. The stock should not be budded unless the sap is in circulation, which is assured if the bark will detach itself easily, when gently lifted, from the wood.
There are many ways of performing the different systems, in preparing and inserting the Buds, &c., and all may prove more or less successful if undertaken when the Buds and stock are both in a suitable condition. The principal methods are Shield or T-budding, including the Circular, Square, and Inverted forms; Flute or Tube-budding, and Annular or Ring-budding.
The first-named method, which is fully described below, is very extensively practised for propagating Roses and stone fruits. It is also coming more in use for the propagation of many other fruit trees, including Apples and Pears, especially new or scarce varieties, as the great advantage of making use of many more of the eyes, to form separate trees, is thereby attained. In large nurseries, where skilful propagators are employed, thousands of trees are annually budded, the majority of them with very successful results. It is, in most cases, preferable to purchase established fruit trees, as cultivators require the produce much quicker than they could get it by propagating trees themselves. The same system of Budding is, however, applicable for increasing Roses; and this may be adopted with every chance of success by even a cottager, if he takes the necessary care in performing the work.
