Verivation. From platys, ample; in allusion to its spreading branches and shady foliage. The 

 name of plane tree is applied, in Scotland, to the WVer PseCldo-/'latanus (seep. 414.); probably 

 because the French, according to Parkinson, first called that the plane tree, from the mistake of 

 Tragus, who fancied, from the broadness of its leaves, that it was the plane tree of the ancients. 



Description, cfc. Lofty deciduous trees, with widely spreading branches 

 dense foliage, and bark scaling off in hard irregular patches. Natives of the 

 east of Europe, west of Asia, and north of Africa, and of North America. 

 In Britain, they are chiefly planted for ornament, and they succeed in any free 

 moist soil, in a sheltered situation. They are readily propagated by lavers 

 or even by cuttings, and sometimes by seeds. The cause of the falling off of 

 the bark. Dr. Lindley states to be the rigidity of its tissue; on account of 

 which it is incapable of stretching as the wood beneath it increases in dia- 

 meter. i^Nat. Syst., ed. 

 2., p. 187.) There are 

 only two species intro- 

 duced into Europe ; one 

 of which, P. orientalis, 

 is found to be hardier 

 than P. occidentalis, 

 though the latter grows 

 more rapidly, attains a 

 larger size, and may be 

 propagated much more 

 readily by cuttings. Both 

 species ripen seeds in 

 Britain, in fine seasons. P. occidentalis is readily known from P. orientalis, 

 in the winter season, by its bark scaling off much less freely, or, in young or 

 middle-sized trees, scarcely at all ; and, in the summer season, by its leaves 

 being but slightly lobed (see Jig. 1932. a), instead of being palmate like those 

 of P. occidentalis, as shown m fg. 1952. b ; and by its globular catkins, or 

 balls, as they are commonly called, being nearly smooth, while those of P. 

 orientalis are rough. The appearance of these catkins, or balls, hanging from 

 the tree by long threads, in winter, when it is without leaves, is peculiarly 

 graceful ; whether they hang from the perpendicular or from the horizontal 

 branches (see Jigs. 1953. and 1954.); reminding us of the divi ladner of 

 Ceylon, the Tabernaemontana alternifolia of botanists (fg. 1954.); which, it 

 is fabled, was the forbidden fruit of Paradise. (See Mag. Nat. Hist., vol. v. 

 p. 449.) It is a singular fact, that many of the large trees of P. occidentalis 

 in Britain, more especially in England, were so far injured by a frost in May, 

 1809, that they have since died.
