The =Oriental= or =Common London Plane= (_Platanus orientalis acerifolia_).—This variety of the oriental plane stands first in the category of select town trees. Not only does it grow vigorously in towns, but it is peculiarly well adapted for withstanding smoke and other impurities of the atmosphere. Repeated experiments have clearly proved that in London this tree flourishes better than any other, and a visit to the Thames Embankment and several of the urban districts will substantiate the statement; while the fine old tree which still exists in Cheapside, and the equally beautiful specimen which has hardly room for perfect development in the Court of Stationers’ Hall, Ludgate Hill, afford other examples of how well suited this handsome tree is for doing battle with the adverse conditions peculiar to the great metropolis. As a diversity of opinion has existed about which variety of plane it is that grows with such vigour in and around London, it may be stated that, on a careful examination of a large number of specimens, the variety _P.O. acerifolia_ was found not only more commonly distributed, but, likewise, better suited for town planting than the typical _P. orientalis_. This valuable variety is readily distinguished from the normal plant by the less deeply divided leaves, and from the American plane (_P. occidentalis_), with which it is sometimes confounded, by the many fruit “balls” which are attached to each peduncle, the fertile catkins of _P. occidentalis_ being, for the greater part, produced singly. But not only for its value as a town tree is the oriental plane much sought after, but the giant proportions to which it attains, coupled with the handsome, finely-cut leaves and easy habit of growth, render it one of our most desirable ornamental trees. Further, it is of the easiest culture, succeeding extremely well in soils of very opposite qualities. Taking everything into consideration, we question whether any other of our forest trees is equal in value to the plane for purposes of town planting. The =Maidenhair Tree= (_Ginkgo biloba_).—The maidenhair or ginkgo tree is one of the most valuable that can be planted in the impure atmosphere of a town garden. Few trees can compare with the one in question for withstanding the deleterious effects produced on vegetation generally by coming in too close contact with the impurities of our great centres of industry. The ample delicate-green foliage betrays—even late in the season, and when about to be cast off—little evidence of the fierce struggle that must almost constantly go on between vegetation and the smoke and filth of our towns and cities. That the thick, leathery leaves and strong constitution of the tree play an important part in keeping it free from disease is clearly evident, while the annual renewal of the leaves enables it to cast off the sooty nodules which work such havoc on the tender foliage of most evergreen trees.
